PIPE FITTINGS

INTRODUCTIONPIPE FITTINGSOneSteel is Australias largest distributor of Pipes, Pipe Fittings, Valves and associated accessories. The OneSteel distribution network offers more than 100 outlets throughout Australia, comprising: OneSteel Piping Systems Capital cities and selected regional centres OneSteel Fire Systems OneSteel Metaland Capital cities, specialising in fire and associated plumbing services Regional cities and towns in all states

The "Pipe Fittings" catalogue is part of a comprehensive series of catalogues, brochures and data sheets which are provided to our customers and associated industry groups. This catalogue describes our range of pipe fittings which are principally manufactured in carbon steel, cast ductile iron and malleable iron. A separate catalogue describes our range of stainless steel pipes and fittings.

In Australia we have two broad groups of standards which govern the design and manufacture of our products, viz: British / Australian Standards Generally covering cast iron and mild steel fittings for low-to-moderate pressures, for commercial and light industrial applications. In this group we also offer selected products to DIN standards. Generally covering carbon steel and alloy steel fittings for higher pressures and temperatures and typically used in the oil, gas, chemical and heavy processing industries.

American Standards

Our customers tend to work predominantly with one standard or the other. For your convenience we have grouped most of the products accordingly. The detailed contents are shown on the opposite page. For further information please contact your local OneSteel sales office. Details of our locations may be found on our website at www.onesteel.com.au. Our catalogues are provided for your assistance. However we are obliged to draw your attention to the following: OneSteel provides the information contained in this brochure as a guide only for your information.

GALVANISED MALLEABLE FITTINGSMATERIALSBlackheart Malleable Iron castings.

WORKING PRESSURES (except flanges)Recommended maximum working pressures are 1379 kPa for water and 1034 kPa for steam, air, gas and oil. NOTE: Working pressures may also be limited by relevant Pressure Piping Codes or Industry regulations.

DIMENSIONS generally to ASME B16.3 or JISB2301, depending on manufacturing source. JIS B2301 dimensions are generally considered to be corresponding values to BS143 and BS1256, although some sizes are not exact equivalents.

THREADING

is BSP pipe thread, to BS.21 (AS 1722, Part 1). The specification for BS 143 fittings is: Taper External (Series R) Taper Internal (Series RC) The specification for BS 1256 fittings is Taper External (Series R) Parallel Internal (Series RP) Our stock fittings are usually BS 143 taper/taper, as this is believed to offer superior sealing characteristics due to greater thread contact (refer illustration below). Taper/taper threads are also being specified by increasing numbers of Gas Authorities, for the same reason.

UNEQUAL SIZESWhen ordering Reducing Sockets, Nipples, Bushes and Elbows, always state largest size first e.g. 80 x 40 bush. When ordering 3- or 4- way fittings, the sizing sequence illustrated below should be adopted.

BLACK AND GALVANISED STEEL UNIONSBLACK STEEL UNIONS are used in a wide range of make-and-break joints requiring periodic disconnection. Available in Steel-Steel, Steel-Bronze and Bronze-Bronze seats in Female-Female and Male-Female types. Black Steel Unions are all-purpose unions coated in black oxide to give protection to the fitting until assembled to piping. ZINC-COATED UNIONS are Electro Zinc Plated. This process gives a complete coating both externally and internally which protects the Union at thread and vital seat areas.

DENSO CORROSION PROTECTION SYSTEMSDENSO PETROLATUM SYSTEMThe Denso Multi-purpose long life corrosion protection system is a multi-component system which remains permanently plastic and flexible and offers excellent conformability and shelf life. Based upon blended Petrolatum and selected inhibitors the system provides unrivalled corrosion protection in terms of surface preparation requirements and ease of application. It is ideal for in-situ and shop application alike.

COLOURTAPE SYSTEMDenso Steelcoat 300 System comprises a selected coloured petrolatum tape (Denso Colour Tape) and compatible neutral coloured mastic (Denso Superlight Mastic) which is ideally suited for small to medium diameter pipes. No primer is necessary and application by hand or wrapping machine is quick and easy. The choice of tape colours gives an attractive finished appearance and is also ideal for colour coding when necessary. A clear adhesive tape (Denso Clear Tape) can be utilised as an additional outerwrap to provide plastic sealing properties and extra mechanical protection.

ULTRAFLEX 1500 SYSTEMDenso Ultraflex pipeline tapes are the first pipeline tapes ever with an Ultraflex polymer backing film which combines the mechanical properties of PE and the conformability of PVC. This combined with a uniquely blended Superbond polymer mastic adhesive results in a product which offers the pipeline owner the assurance needed in selecting a pipeline coating with confidence to combat the threat of pipeline corrosion. Ultraflex offers the user ease of application by hand or machine, the choice is yours. Denso Ultraflex is a durable, high conforming tape with controlled elasticity that assures an aggressive bond to self, pipe and shop coating.

BUTTWELD FITTINGSMATERIAL SPECIFICATIONSSEAMLESS CARBON STEEL: Buttweld fittings are made to the material specifications of ASTM A234, grades WPA, WPB or WPC; which correspond exactly to the material specifications of seamless carbon steel pipes to ASTM A106 grades A, B, or C. LOW TEMPERATURE FITTINGS: For low temperature applications, a wide range of fittings in materials to ASTM A420 can be offered. HIGH YIELD FITTINGS: On an indent basis, we offer a range of fittings having a high yield strength suitable for use with the various grades of API 5LX linepipe. FERRITIC ALLOY STEEL FITTINGS: For high temperatures, OneSteel offers a range of alloy fittings to ASTM specification A335, in the following grades: P1 - 1/2%Mo P5 - 5%CR1/2%Mo P7 - 7%Cr 1/2%Mo P9 - 9%Cr1%Mo AUSTENITIC STAINLESS STEEL FITTINGS: OneSteel stocks stainless steel fittings in ASTM grades 304L and 316L. Other grades available to order. P11 - 11/4%Cr1/2%Mo P12 - 1%Cr1/2%Mo P22 - 21/4%Cr1%Mo

WORKING PRESSURESButtweld fittings are designed and manufactured to standards which demand a bursting strength equal to or greater than that of Seamless Pipe of the same material specification, nominal diameter and wall thickness, and their allowable working pressures are equal to those shown for pipe in the OneSteel pipe catalogue. Maximum allowable working pressures for: CARBON STEEL FITTINGS: Equal to seamless pipes to ASTM A106, (Grade B unless otherwise specified). HIGH TEMPERATURE (Ferritic Alloy): Fittings (Grades WP5, WP11 etc), are equal to seamless pipes to ASTM A335 of similar grade (P5, P11, etc). LOW TEMPERATURE: Fittings (Grade WPL6-ASTM A420) are equal to seamless pipes to Grade 6 - ASTM A333. STAINLESS STEEL: Fittings (Grades 304 and 316, also 304L and 316L) are equal to stainless steel pipes to ASTM A312 of equal grade and schedule. NB: Stainless Steel Fittings in Schedule 10S and 5S are not designed for applications where pressure is a prime consideration, and the relevant standard, MSS SP43 establishes the working pressures substantially lower than those yielded by the application of the basic formula.

QUALITY CONTROLButtweld fittings from OneSteel are subject to strict quality control. Manufacturers plants are visited regularly, and the source of mother tube is verified. Test certificates are available as required. OneSteel liaises with major customers to ensure that all fittings are obtained from sources approved by the customer or by specific industry groups.

OLET FITTINGSWELDOLETSUsed to make full size and reducing branch connections from 6 to 750mm from run pipes 10 to 900mm in order to: Facilitate header construction. Construct the joint to full pipe strength. Meet code design requirements for reinforced branch joints. Improve flow. Assure economical, clean and strong connections.Thredolet Weldolet

Sockolet

THREDOLETS AND SOCKOLETSUsed for making relatively small branch outlet connections. Threadolets and Sockolets are half couplings that are bevelled for convenience, tapered for strength, flared for fluid flow and drop forged for the ultimate in strength and ruggedness.Elbolet

ELBOLETS AND LATROLETSUsed for making threaded, socket-weld or buttweld outlets tangentially to elbows or as 45 branch connections on straight pipe. The design provides for a full penetration weld. These fittings provide greatly improved flow conditions compared with 90 connections and are advantageous for many instrument connection applications.

HOW IT WORKSEach outlet size indicated on chart is designed to fit a number of run pipe sizes, E.G. The 15mm fitting marked 900-100x15 will fit all run pipe sizes from 100mm to 900mm. When placed on a 900mm run pipe, there will be a maximum gap of 1.6mm between the top of the run pipe and the base of the fitting at the crotch as shown on sketch. This gap is negligible when welding.1.6mm MAX GAP 900mm RUN PIPE

SOCKET-WELD REDUCER INSERTS ASTM A105 FORGINGSThe purpose of socket-weld reducer inserts is to avoid the delays and extra costs that naturally occur in producing regular socket-weld fittings with reduced outlets. Designed for use with straight size fittings, reducer inserts serve the same purpose as threaded bushings used with screwed fittings. The drawing at right illustrates the simplicity of their application.

FLANGES TO AMERICAN STANDARDSSPECIFICATIONSForged Carbon, Alloy and Stainless Steel Flanges to American Standards are designed for use with pipes and fittings to American Standards, but can also be attached, in certain sizes to pipes made to British and Australian Standards.

ANSI FLANGES

SIZES 15 - 600mmCLASS 150, 300, 400, 600, 900, 1500 & 2500 Dimensions shown are for Flanges made to the dimensional requirements of ASME B16.5 which is the accepted American Standard for all Flanges in sizes to 600mm bore.

SIZES ABOVE 600mmSteel Flanges above 600mm bore are made to various standards, as follows: CLASS 150, 300, 400, 600, 900 Dimensions to *MSS-SP44 or BS 2393. OneSteel stocks slip-on and weld-neck flanges to BS 3293 and blinds to MSS SP44. *MSS-SP44 A Standard developed by the Manufacturers Standardisation Society (of the Valves and Fittings Industry) to provide uniform dimensions of flanges for use with high pressure pipelines larger than 600mm diameter. These designs were predicated on flanges being used with API 5LX line-pipe of 52,000 lbs. minimum yield strength, and were proportioned accordingly. This Standard can be taken as being the extension of ASME B16.5 in sizes above 600mm bore.

API 605 gives dimensions for flanges above 600mm, which are different to MSS, BS and ASME.

FLANGES TO AMERICAN STANDARDSLARGE DIAMETER FLANGE STANDARDSASME B16.1b This Standard establishes dimensions for Class 250 Cast Iron Flanges above 600mm, (as ASME B16.1 gives dimensions for large diameter Class 125 Cast Iron Flanges). API 605 American Petroleum Institute Standard intended primarily for use in Oil and Gas production. API 605 dimensions DO NOT match ASME, MSS or BS dimensions of similar pressure class. AWWA C207-54T This is a Standard published by the American Waterworks Association for steel Flanges to be used on waterworks and sewerage pipes. These flanges match Class 125 Cast Iron Flanges (ASME B16.1) in most dimensions. CLASSES 125LW, 175 & 350 These are Standards developed over the years by a number of manufacturers, not all using exactly the same dimensions. TEMA FLANGES The Tubular Exchangers Manufacturers Association (TEMA) lays down standards for dimensions and material specifications for Shell Flanges, Cover Flanges, Long Welding Necks for Nozzles and other heat exchanger components. BS.3293 This British Standard established dimensions for flanges for petroleum industry use, in Class 150, 300, 400 and 600, in sizes above 600mm, which correspond exactly to those of MSS SP-44 in Class 300, 400 and 600. Class 900 is not included in the British Standard, but dimensions are given for Class 150, 600-700mm which are similar to those of ASME B16.1, Class 125. BS.1560 This British Standard is based on ASME B16.5, and lists Steel Pipe Flanges to the same dimensions, pressure classes and in the same sizes as the American Standard up to 600mm. GUIDE TO MATERIAL SPECIFICATIONS

ANSI FLANGESMATERIAL SPECIFICATIONS American Standard Pipe Flanges are manufactured in a variety of Carbon, Alloy and Stainless Steels and selection of a particular grade is determined by the usual criteria of pressure/temperature requirements and corrosion resistance. Since these factors determine pipe and fittings to be used in a piping system, it is then necessary only to select flanges of a similar material.The classifications are used to group materials for Flanges Class 150 through Class 2500. * 150 lb and 300 lb classes only.

FLANGES TO AMERICAN STANDARDSMETHODS OF ATTACHMENT

WELDING NECK FLANGESThis type of flange is attached by buttwelding to the adjoining pipe or shell. The weld may be made either manually or automatically with or without a backing strip. Sound welds are readily obtained with any recognised welding procedure.

SLIP - ON FLANGESAlthough recommended practice in attaching Slip-On type flanges is to weld both at the flange hub and the pipe end, for mild service conditions only one is sometimes employed. In this case the weld is normally made at the pipe end.

THREADED FLANGESThreaded flanges are, of course, attached by screwing to threaded pipe ends.

LAP JOINT FLANGESLap joint flanges are most frequently used with lap joint stub ends, (Type A), although in some cases the lap is formed on the pipe end. Since they are free to rotate or swivel, there is no problem of bolt hole alignment. Such joints may be readily broken for inspection, cleaning, etc. The radius at the ID of the flange face accommodates that at the back of the lap, thus permitting more uniform application of loading. Lap Joint flanges find their most common application when used with stainless steel stub ends.

SOCKET-WELD FLANGESOneSteel stocks Type B stub ends which are used with normal slip-on weld flanges ie Lap joint backing flanges are not required. In attaching socket-weld flanges, the pipe end is inserted into the socket and then welded at the flange hub. An inside weld at the pipe end is frequently made for greater strength or, with grinding, to provide a smooth bore without pockets or recesses.

FLANGES TO AMERICAN STANDARDSGASKET SURFACEFlanges, and other products designed for bolted connection, when furnished with raised face (or flat face) may have any type of gasket surface finish that is required. The more common finishes are described in the following paragraphs.

1 STOCK FINISH: This is a continuous spiral groove. For nominal sizes 300mm and smaller it is generated by a 1.58mm radius roundnosed tool at a feed of 0.79mm per revolution. For sizes above 300mm the tool nose is radiused to 3.17mm and the feed is 1.19mm per revolution. NB OneSteel stocks flanges with surface finish in the range 3.2-6.3 microns, ideal for use with both spiral-wound and ring gaskets. 4 SMOOTH FINISH: This finish, which can be produced by several shapes of tools, shows no definite tool markings apparent to the naked eye. In the past this finish was sometimes known as Smooth Plane. This term however, should be avoided because of a tendency to confuse it with flat faced which, of course, applies to the flange facing and not to the gasket surface finish.

2 SPIRAL SERRATED:

1

2

This too, is a continuous spiral groove, but it differs from the stock finish in that the groove is generated with a 90 included angle V tool. The groove is .39mm deep and the feed is .79mm for all sizes.

4

55 COLD WATER FINISH: Produced by using a wide tool at high speeds, this finish is equivalent to that of a ground surface. It is mirror-like in appearance and surfaces finished in this manner are usually expected to be used without gaskets.

3 CONCENTRIC SERRATED: (Not illustrated) As the name suggests this surface finish is made up of concentric grooves. A 90 included angle V tool is used and the grooves are .39mm deep and .79mm apart.

FLANGES TO AMERICAN STANDARDSORIFICE FLANGESOrifice Flanges are used to locate an orifice plate in a pipeline and to provide a tapped opening upstream and downstream of the plate. The tapped openings are connected to pressure recording instruments and the pressure differential between the upstream and downstream readings is translated into a measurement of flow in the line. Orifice Flanges are always supplied in pairs or sets and are available with slip-on, weldneck or threaded connections. To facilitate the insertion and removal of orifice plates, the flanges are provided with a set of jacking screws. By backing off the flange bolts and tightening the jacking screws, the flanges are forced apart, allowing access to the orifice plate. Orifice flanges are available from all OneSteel branches. Orifice plates can also be supplied to customer requirements. Please contact your OneSteel Sales Office for further details.

SPIRAL WOUND GASKETS Constructed from a spirally wound V section austenitic stainless steel strip, with a non-asbestos filler between each turn. Offering high pressure and temperature resistance and ease of replacement. There are two popular styles in the Klinger range of spiral gaskets: SELF CENTERING, MEDIUM PRESSURE TYPE CR Type CR gaskets have an outer ring which facilitates accurate centering of the gasket in the joint, provides additional radial strength, helps prevent blow-out and serves as a reference point to determine the amount of compression during bolt pullup. Recommended up to Class 600 flanges or equivalent, general service. Maximum temperature 350 with graphite filler check range suitability. SELF CENTERING, HIGH PRESSURE TYPE CRIR Type CRIR gaskets are the same construction as Type CR but have an additional inner ring. The inner ring provides additional radial strength, acts as a barrier to vacuum and corrosive/abrasive media. Recommended for Class 150 to 2500 flanges or equivalent, and any application requiring advantages of an inner ring. Maximum temperatures 540C with graphite filler check flange suitability. Higher temperature rated materials available on request.Spiral Gasket Type CRIR
