AWWA Standard

This document i s an American Water Works Association (AWWA) standard. I t i s not a specifcation. AWWA standards

describe min imum requirements and do not conta in a l l of the engineering and administrative information normal l y

conta ined in specifcations. The AWWA standards usual l y conta in options that must be eva luated by the user of the

standard . Unti l each optiona l feature is specifed by the user, the product or service i s not ful l y defned. AWWA pub -

l i cation of a standard does not consti tute endorsement of any product or product type, nor does AWWA test, certi fy,

or approve any product. The use of AWWA standards is entirely voluntary. Th is standard does not supersede or take

precedence over or d isplace any appl icable law, regu lation , or code of any governmenta l authori ty. AWWA standards

are intended to represent a consensus of the water industry that the product described wi l l provide satis factory ser-

vice. When AWWA revises or wi thdraws th is standard , an ofcia l notice of action wi l l be placed on the frst page of the

Ofcia l Notice section of J ournal – American Water Works Association . The action becomes efective on the frst day of

the month fol lowing the month of J ourna l – American Water Works Association publ ication of the ofcia l notice.

American National Standard

An American National Standard impl ies a consensus of those substantia l l y concerned wi th i ts scope and provisions.

An American National Standard is intended as a gu ide to a id the manu facturer, the consumer, and the genera l publ ic.

The existence of an American National Standard does not in any respect preclude anyone, whether that person has

approved the standard or not, from manu facturing, marketing, purchasing, or using products, processes, or proce -

dures not con forming to the standard. American National Standards are subject to period ic review, and users are cau -

tioned to obta in the la test ed i tions. Producers of goods made in con formity wi th an American National Standard are

encouraged to state on their own responsibi l i ty in advertising and promotional materia ls or on tags or labels that the

goods are produced in con formity wi th particu lar American National Standards.

Caution notiCe : The American National Standards I nsti tute (ANSI ) approval date on the front cover of th is standard

ind icates completion of the ANSI approval process. Th is American National Standard may be revised or wi thdrawn at

any time. ANSI procedures require that action be taken to reafrm, revise, or wi thdraw th is standard no la ter than fve

years from the date of publ ication . Purchasers of American National Standards may receive current information on

Foreword

Tis foreword is for information only and is not a part of ANSI*/AWWA C200.

I. Introduction.

I.A. Background. Tis standard covers butt-joint welded straight-seam or

spiral-seam steel pipe, 6 in. (150 mm) and larger, for transmission and distribution of

water, including fabrication of pipe, requirements of welding operations, permissible

variations of thickness and dimensions, preparation of ends, fabrication of special

sections, inspection, and test procedures.

I.B. History. Te frst AWWA steel pipe standards issued were 7A.3 and

7A.4, published in 1940. Standard 7A.4 pertained to steel pipe smaller than 30 in.

(750 mm) in diameter, and 7A.3 pertained to steel pipe 30 in. (750 mm) in diameter

and larger. Subsequently, in recognition that some pipe used in water utility service

was manufactured in steel mills rather than in a fabricator’s shop, two new AWWA

standards were issued in 1960. AWWA C201 replaced 7A.3 and pertained to all pipe,

regardless of diameter, manufactured in a fabricator’s shop from steel sheet or plate.

Te physical and chemical properties are properties of the sheet or plate from which the

pipe is made. Te properties are a function of the steel mill practice and are not afected

signifcantly by fabricating procedures. AWWA C202 replaced 7A.4 and pertained

to mill pipe, which is normally produced in a production pipe mill. Te specifed

physical and chemical properties are those of the completed pipe. Physical testing is

performed on the pipe rather than on the steel from which it originates. In many cases,

the physical properties are signifcantly afected by the pipe-manufacturing procedure.

AWWA C201 was revised in 1966, and AWWA C202 was revised in 1964. Both

AWWA C201 and AWWA C202 were superseded by AWWA C200-75, approved by

the AWWA Board of Directors on Jan. 26, 1975.

AWWA C200 includes all types and classes of steel pipe, 6 in. (150 mm) in diam-

eter and larger, used in water utility service, regardless of the pipe-manufacturing

source. With adequate quality assurance, pipe manufactured in a fabricator’s shop or

in a steel pipe mill is suitable for water utility service.

By reference, AWWA C202 (which pertained to mill-type steel water pipe) included

API† 5L and API 5LX pipe grades manufactured to API standards for high-pressure

applications. With the inclusion of ASTM A570/A570M and ASTM A572/A572M

high-strength steels in AWWA C200-75, API high-pressure pipe was omitted from

AWWA C200-75 as being redundant. API 5L and API 5LX pipe grades fully met all

requirements of AWWA C200 and could be used for water utility applications if dic-

tated by availability or other economic considerations.

AWWA C200-75 introduced design criteria for determination of wall thickness

to meet internal pressure conditions. Tese criteria facilitated the selection of the opti-

mum combination of thickness and material for steel pipe.

Revisions in AWWA C200-86 included clarifcation of forming for lap-joint

ends and gasketed ends and testing of O-ring gaskets. Subsequent editions of this

standard were approved by the AWWA Board of Directors on June 23, 1991; Feb. 2,

1997; June 12, 2005, and June 10, 2012. Tis edition was approved on Jan. 14, 2017.

I.C. Acceptance. In May 1985, the US Environmental Protection Agency

(USEPA) entered into a cooperative agreement with a consortium led by NSF

International (NSF) to develop voluntary third-party consensus standards and a

certifcation program for direct and indirect drinking wat er additives. Other members of

the original consortium included the Water Research Foundation (formerly AwwaRF)

and the Conference of State Health and Environmental Managers (COSHEM). Te

American Water Works Association (AWWA) and the Association of State Drinking

Water Administrators (ASDWA) joined later.

In the United States, authority to regulate products for use in, or in contact with,

drinking water rests with individual states.* Local agencies may choose to impose

requirements more stringent than those required by the state. To evaluate the health

efects of products and drinking water additives from such products, state and local

agencies may use various references, including

1. Specifc policies of the state or local agency.

2. Two standards developed under the direction of NSF:† NSF/ANSI 60,

Drinking Water Treatment Chemicals—Health Efects, and NSF/ANSI 61, Drinking

Water System Components—Health Efects.

3. Other references, including AWWA standards, Food Chemicals Codex,

Water Chemicals Codex,‡ and other standards considered appropriate by the state or

local agency.

* Persons outside the United States should contact the appropriate authority having jurisdiction.

Various certifcation organizations may be involved in certifying products in accor-

dance with NSF/ANSI 61. Individual states or local agencies have authority to accept

or accredit certifcation organizations within their jurisdictions. Accreditation of certi-

fcation organizations may vary from jurisdiction to jurisdiction.

Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does

not stipulate a maximum allowable level (MAL) of a contaminant for substances not

regulated by a USEPA fnal maximum contaminant level (MCL). Te MALs of an

unspecifed list of “unregulated contaminants” are based on toxicity testing guidelines

(noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A

procedures may not always be identical, depending on the certifer.

ANSI/AWWA C200 does not address additives requirements. Tus, users of this

standard should consult the appropriate state or local agency having jurisdiction in

order to

1. Determine additives requirements, including applicable standards.

2. Determine the status of certifcations by parties ofering to certify products

for contact with, or treatment of, drinking water.

3. Determine current information on product certifcation.

II. Special Issues.

II.A. Advisory Information on Product Application.

1. Basis of design. ANSI/AWWA C200 pertains to the manufacture and testing

of the steel-pipe cylinder. Coatings that protect against corrosion are referenced in Sec.

4.12. ANSI/AWWA C604, Installation of Buried Steel Water Pipe, 4 In. (100 mm) and

Larger, provides feld installation guidelines. Overall design of steel pipelines is described

in AWWA Manual M11, Steel Water Pipe—A Guide for Design and Installation .

Design of the wall thickness of steel pipe is primarily afected by internal pressure,

including working, transient, and test pressures. Other factors that may infuence the

designed wall thickness are external loads, including trench loading and earth fll;

special physical loading, such as continuous-beam loading with saddle supports or

ring girders; vacuum conditions; type of joint used; and practical considerations for

handling, shipping, lining, and coating or similar operations.

Te design techniques described in AWWA Manual M11 are used to determine

required wall thicknesses of steel pipe. Te purchaser may establish and specify a wall

thickness determined to be satisfactory for all conditions, including internal pressure,

trench loadings, special physical loadings, and handling. Selection of design stresses and

defection limits should be made with regard to the properties of the lining and coating

materials used. Te purchaser may alternatively specify the performance criteria for the

pipeline, in which case the manufacturer, using AWWA standards, provides the wall-

thickness calculations for purchaser acceptance. Performance criteria provided should

include internal design pressures, external loading, and any other special conditions. Te

manufacturer is allowed to select materials and manufacturing processes within the limi-

tations of this standard to produce pipe to the wall thickness required to additionally

satisfy the specifed performance criteria. Tis thickness should govern if it is greater than

the wall thickness specifed by the purchaser. Tickness tolerances for pipe are governed

by the requirements of this standard.

2. Application. Tis standard describes the requirements for steel water pipe

for use in water transmission and distribution under normal circumstances. It is the

responsibility of the purchaser for each project to determine if any unusual circum-

stances related to the project require additional provisions that are not included in the

standard. Such special conditions might afect design, manufacture, quality control,

corrosion protection, or handling requirements.

3. Brittle fracture precautions. Sec. 4.5.2 provides test requirements for steel

to ensure notch toughness. Under certain conditions where a restrained pipeline with

welded lap joints will be used, notch toughness verifcation may be necessary, see also

ANSI/AWWA C206, Field Welding of Steel Water Pipe.

4. Testing of special sections. Sec. 5.2.2 provides for nondestructive testing of

the weld seams of special sections. Tis testing should be adequate for normal condi-

tions previously discussed under Item 2, Application (above).

5. Roundness of pipe. Te roundness of pipe during handling, shipping, joint

makeup, and backflling should be covered in the purchaser’s documents. When

requested, the pipe is delivered with internal bracing for shipping and handling pur-

poses. Although not generally designed for such, this bracing can assist in limiting the

maximum vertical defection of the pipe during installation and backflling operations.

Bracing design for this purpose is the responsibility of the constructor.

II.B. Chlorine and Chloramine Degradation of Elastomers. Te selection of

materials is critical for water service and distribution piping in locations where there is a

possibility that elastomers will be in contact with chlorine or chloramines. Documented

research has shown that elastomers such as gaskets, seals, valve seats, and encapsulations

may be degraded when exposed to chlorine or chloramines. Te impact of degradation

is a function of the type of elastomeric material, chemical concentration, contact surface

area, elastomer cross section, and environmental conditions as well as temperature.

Careful selection of and specifcations for elastomeric materials and the specifcs of their

application for each water system component should be considered to provide long-term

usefulness and minimum degradation (swelling, loss of elasticity, or softening) of the

elastomer specifed.

II.B.1 Gasket Degradation Study. A pipe gasket, having the hardness of a

compressed elastomer with a large mass relative to the small exposed surface area, thus

experiences minimal degradation. Tis was validated in a research paper reported in

the Journal - AWWA ,* where the pipe gasket degradation in a 110 mg/L chloramine

solution was found to degrade just the exposed surface.

SECTION 4: REQUIREMENTS

Sec. 4.1 Permeation

Te selection of materials is critical for water service and distribution piping

in locations where there is likelihood the pipe will be exposed to signifcant con-

centrations of pollutants composed of low-molecular-weight petroleum products

or organic solvents or their vapors. Documented research has shown that pipe

materials (such as polyethylene and polyvinyl chloride) and elastomers, such as

those used in jointing gaskets and packing glands, are subject to permeation by

low-molecular-weight organic solvents or petroleum products. If a water pipe must

pass through such a contaminated area or an area subject to contamination, con-

sult with the manufacturer regarding permeation of pipe walls, jointing materials,

and so forth before selecting materials for use in that area.

Sec. 4.2 Materials

Materials shall comply with the requirements of the Safe Drinking Water Act

and other federal regulations for water systems as applicable.

Sec. 4.3 Drawings

When pipe detail drawings are required to illustrate compliance with the pur-

chaser’s requirements, they shall be subject to acceptance by the purchaser.

Sec. 4.4 Calculations

If the manufacturer is required to determine the wall thickness, the manu-

facturer’s calculations of wall thickness shall be submitted to and accepted by the

purchaser before the start of manufacturing.

Sec. 4.5 Selection of Materials

4.5.1 General. If the purchaser’s documents do not specify the type of

pipe or steel, the manufacturer shall select the type of pipe and steel from this stan-

dard to meet the design requirements of the purchaser’s documents. Pipe shall be

fabricated from plate, sheet, or coil from Table 1 . Te steel shall be fully killed and

shall conform to fne-grain practice.

4.5.2 Charpy impact testing. Charpy impact testing shall be utilized to eval-

uate steel used to fabricate pipe that will be restrained in its application. Restrained

pipe with a minimum service temperature below 30°F (–1°C) should be evaluated

by other methods, such as ASME Boiler and Pressure Vessel Code (BPVC) Section

VIII, Division 1, UG-20(f). Steel for pipe in excess of 2.0-in. (50-mm) thick shall be

Charpy tested. Steel for pipe 0.500 in. (13 mm) or thinner does not require Charpy

testing. Other pipe thicknesses shall be evaluated using Figure 1. Plot the minimum

service temperature and the steel thickness. When a minimum service temperature is

not provided by the purchaser, 32°F (–0°C) shall be used for the evaluation. Materi-

als that comply with Sec. 4.5.1 are Group 1. Group 1 materials that plot below the

Group 1 line require Charpy testing. All other materials are Group 2. Group 2 mate-

rials that plot below the Group 2 line require Charpy testing. Materials that plot on

or above the applicable line do not require Charpy testing.

When Charpy testing is required, Charpy V-notch (CVN) specimens shall

be prepared and test results interpreted in accordance with ASTM A370. CVN

shall be heat-lot tested; specimens shall be taken in the transverse direction at

30°F (–1°C) with a minimum average full size criteria of 25 ft·lbf (33.9 N·m).

Heat-lot testing for plate is defned in ASTM A673. Heat-lot testing for coils is

defned as two coils per heat, with test coupons being taken from the outer wrap

Sec. 4.11 Preparation of Ends

Pipe ends shall be smooth and free of notches, weld spatter, and burrs.

4.11.1 Ends for mechanically coupled feld joints. Ends for mechanically

coupled feld joints shall be plain, grooved, or banded. Te outside surfaces of ends

of plain-end pipe shall be free from surface discontinuities and shall have the lon-

gitudinal or spiral welds ground fush with the plate surface for a sufcient distance

from the ends to permit the coupling gaskets to form a watertight seal against the

pipe wall. Grooved or banded ends shall be prepared to ft the type of mechanical

coupling to be used.

4.11.2 Ends for lap joints for feld welding. Te bell ends shall be formed

by expanding with segmental dies on a hydraulic expander, pressing on a plug die,

or by rolling. After forming, the minimum radius of the curvature of the bell end

at any point shall not be less than 15 times the nominal thickness of the pipe wall.

Bell ends formed by rolling shall be completed in a manner to avoid impairment

of the mechanical properties of the steel shell. Joints shall permit a lap, when the

joint is assembled, of at least 1 in. (25 mm). Te longitudinal or spiral welds on

the inside of the bell end and the outside of the spigot end on each section of pipe

shall be ground fush with the plate surface. Te inside edge of the bell and the

outside edge of the spigot shall be scarfed or lightly ground to remove sharp edges

and burrs.

4.11.3 Plain-end pipe. Pipe shall be provided with a plain right-angle cut.

Burrs at the ends of the pipe shall be removed.

4.11.4 Beveled ends for feld butt joint welding. For feld butt welding of

circumferential joints, the ends shall be beveled to an angle of 30 degrees, mea-

sured from a line drawn at right angles to the axis of the pipe, with a tolerance

of +5 degrees, –0 degrees, and with a width of root face (or fat at the end of the

pipe) of 1 /16 in. ±1 /16 in. (1 .6 mm ±1.6 mm). Other bevel angles may be used if prior

approval between purchaser and constructor is obtained. Bevel angles shall be in

accordance with approved WPS.

lap over the pipe ends a minimum of 1 in. (25 mm). Butt straps may be made in

halves or as complete cylinders. Tey may be welded to the pipe by the manufac-

turer or shipped separately. Welds at faying surfaces of the pipe ends and inside the

butt strap shall be ground fush with the plate surfaces for a distance sufcient to

facilitate installing the butt strap.

4.11.6 Bell-and-spigot ends with rubber gasket. Bell-and-spigot ends shall

be designed so that when the joint is assembled, it will be self-centering and the

gasket will be restrained or confned to an annular space so that the gasket cannot

be displaced by movement of the pipe or hydrostatic pressure. When the joint is

completed, compression of the gasket shall not be dependent on water pressure in

the pipe or external pressure and shall maintain a watertight seal when subjected

to the specifed conditions.

Note: AWWA Manual M11 shows several types of bell-and-spigot joints

with rubber gaskets. Other types are available from various pipe manufacturers.

4.11.6.1 Fabrication. Bell-and-spigot ends may be formed integrally with

the steel cylinder or may be fabricated from separate plates, sheets, or special sec-

tions for attachment to pipe ends. Bell ends formed integrally with the cylinder

shall be shaped either by pressing over a machined swage or die or by sizing with

an internal expander. Spigot ends may be formed integrally with the steel cylinder

by rolling with suitable equipment or by welding a preformed shape or fat bars to

the spigot end of the pipe to form a groove of the proper confguration. Welds on

the inside of the bell and outside of the spigot shall be ground fush with the plate

surface for a distance not less than the depth of insertion.

4.11.6.2 Rubber gaskets. Terms relating to rubber or elastomer shall be

defned in accordance with ASTM D1566, Standard Terminology Relating to

Rubber. Te manufacturer shall supply a continuous rubber gasket with smooth

surfaces for each bell-and-spigot joint. All gasket material shall be extruded or

molded in such a manner that any cross section will be dense, homogeneous, and

free of porosity, blisters, pitting, or other imperfections that may interfere with

the proper functioning of the sealing system. Te size and shape of the gasket

cross section shall be designed for continuous deformed contact with both the bell

and the spigot and shall be of sufcient volume to fll the recess provided for the

gasket when the pipe joint is assembled. Gaskets shall be stored in a location that

will minimize gasket exposure to moisture, high temperature, or extremely low

temperatures. Gaskets shall be protected from the direct rays of the sun. When

4.11.6.4 Testing and certifcation. Rubber gaskets shall be tested to

ensure that the material is fully cured and homogeneous, and that the gasket cross

section contains no voids or physical defects that will impair its ability to maintain

compressive strength and provide the necessary volume, as designed. If a splice is

used in the manufacture of the gasket, the part of each gasket that includes a splice

shall be subjected to 100 percent elongation. While stretched, the full splice shall

be inspected. Splices shall be subjected to a bend test. Te bend test for circular

gaskets is defned as wrapping the portion of the unstretched gasket containing the

splice a minimum of 180 degrees around a rod of a diameter equal to, or less than,

the cross-section diameter of the gasket. Any visible separation of the splices during

either the elongation test or the bend test shall result in the rejection of the gasket.

4.11.6.5 Gasket dimensions and tolerances. Gasket diameter and volume

shall conform to the dimensions specifed by the pipe manufacturer. Gasket diam-

eter tolerance shall be ±1.5 percent but not less than ±1 /64 in. (0.40 mm) on all dia-

metrical dimensions. For molded gaskets or gasket material, the permissible fash

shall be maximum of +0.032 in. (0.80 mm). Maximum mold mismatch shall not

exceed 0.010 in. (0.25 mm).

4.11.6.6 Gasket markings: Gaskets shall be molded or permanently

marked with identifcation that will provide traceability to the manufacturer, pipe

size, cord size, or part number, reel or lot number, country where extruded or

molded, and year of manufacture. Molded markings shall not be on the sealing

surfaces.

have the longitudinal or spiral welds on the pipe ground fush with the plate or

sheet surface for a sufcient distance from the ends to allow proper installation of

the fange.

4.11.8 Manufacturing tolerances at ends. Te length of pipe subject to the

stated tolerance shall be that distance that comes in direct contact with the mating

pipe or external appurtenances.

4.11.8.1 Out-of-roundness. Te out-of-roundness of pipe ends shall be

consistent with the diameter and wall thickness of the pipe supplied and the type

of joint. Any out-of-roundness shall be limited to a smooth oval that may be jacked
