2.4 Order of precedence. Unless otherwise noted herein or in the contract, in the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained.

3. DEFINITIONS

This section is not applicable to this standard.

4. GENERAL REQUIREMENTS

4.1 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs.

4.2 Nuclear plant piping. For piping directly associated with a nuclear plant, the requirements of sections 210 and 9890-1 of the applicable ship specifications apply in lieu of the requirements specified herein.


MIL-STD-777F(SH)

12

4.3 Gauge piping. Pressure gauge piping requirements are specified in 803-1385850, except the root valve may be eliminated when the gauge is located on a gauge board that is mounted on a component and is not more than 3 feet from the root connection of the gauge. The use of siphons and flexible connections as a means for providing flexibility is not mandatory, provided the configuration of gauge piping is such that the flexibility requirements of 803-1385850 are met and objectionable vibrations are not transmitted to the gauges on the gauge board. When the gauge/isolation test valve is not mounted on the gauge board, the jam nut and washer shall be removed. Gauge/isolation valves to 803-6397304 may be used as alternatives to the MIL-V-24578 valves required by 803-1385850.

4.3.1 Root valves. Root connections for instrumentation piping shall be in accordance with the following:

a. Where possible, root connections shall be made into the side of pipe or pressure vessels to minimize problems due to air binding or accumulation of foreign materials in the gauge lines.

b. Root connections between the outlet and root valve shall be at least ¼ inch nominal pipe size (NPS). c. Root valves shall be of the same design, material, and rating as valves in the system to which they are

connected, except stellite-faced seats are not required for root valves in steam and drain lines. However, the hardness for these seats shall be Brinell (BHN) 225 minimum.

d. The overall size and weight of the root valves shall be kept to a minimum.

4.4 Thermometer wells. Thermometer wells shall conform to the requirements of 803-1385917 and MIL-T-24270 using materials selected which are compatible with the materials specified for the intended service. Materials other than those specified are acceptable, provided that they are entirely satisfactory in all respects and are approved by NAVSEA.

4.5 Maximum material temperature. The pressure listed for the service categories contained in this schedule, in general (although not in all cases), are system operating pressures. Temperatures indicated, with the exception of Category A – steam systems, are the maximum expected operating temperature. In the case of most cold systems, ambient temperatures of 150 °F have been used. For maximum allowable stresses for piping materials at various temperatures, see section 505 of ship specs or GSO.

4.6 Fire protection. The piping systems, including support structures in high fire hazard spaces, shall be designed to remain operational for a specified temperature, time, and heat flux. The design specification shall specify the time, temperature, and heat flux for which various piping systems are to remain operational for each particular region within the ship. High fire hazard spaces are those compartments protected by high-pressure water mist, heptafluoropropane (HFP), Halon 1301, or CO2 flooding systems.

4.7 Seawater valves. Valves intended for seawater service shall have nickel-copper alloy stems, seats, discs, disc nuts, hinge pins, and side plugs, as applicable. For valves in sizes 2½ inches and above, discs with a nickel-copper alloy facing of ⅛-inch minimum thickness are acceptable in lieu of solid nickel-copper alloy. Nickel-copper-aluminum or nickel-copper-silicon alloy may be used as an alternative to nickel-copper. Bronze valves for other than seawater service may have bronze stems, seats, discs, disc nuts, hinge pins, and side plugs, as applicable.

4.8 Valve approvals. For valves (except valves on many mechanical standard drawings), fittings, and flanges, contractor’s designs previously approved for comparable installations may be substituted for those specified, subject to justification to and approval by NAVSEA. Extensions of the applicability of previously granted waivers or approvals for reasons of shipbuilding expediency are not valid.

4.9 Pressure temperature ratings. For ferrous and special alloy components, selection of the pressure series shall be made in accordance with the pressure temperature ratings of ASME B16.5 or ASME B16.34, as applicable, unless the series is specifically designated in the applicable category. Butt-welded or socket-welded fittings shall be of a schedule or thickness compatible with the service conditions.


MIL-STD-777F(SH)

13

4.10 Butt-weld requirements. Butt-welded ends for valves, fittings, and flanges shall not be used for sizes smaller than 1¼ inches, except where previously approved by NAVSEA, or where inert gas consumable insert type butt-welds are used in sizes down to and including ½ inch, subject to qualification of the procedure by the activity doing the welding. Socket-welded end valves, fittings, and flanges for P-1 piping may only be used in sizes up to and including 2 inches. For welded-end steel valves, fittings, and flanges, the carbon content shall not exceed 0.35 percent.

4.11 Long-radius elbows. The use of long-radius elbows are required to minimize flow turbulence. The use of short-radius elbows is acceptable where space conditions do not permit long-radius elbows.

4.12 Steel valve seat and disc materials. Steel valves, not covered by military specifications or standard drawings in steam and feed systems normally operating at gauge pressures of 150 psi and above, shall have seat and disc seating surfaces hard faced using material in accordance with type MIL-RCoCr-A of MIL-R-17131, or the equivalent. Steel valves in steam and feed systems below 150 psi at saturation temperatures shall have either hard-faced operating seat and disc seating surfaces as specified above, or seats and discs hardened by heat treatment. Special normally open valves not used for throttling, such as solenoid trips, shall have seating surfaces suitable for the service application.

4.13 Threaded joints. Straight threaded connections with seals are permitted in all systems where unions or union-ended components are listed, subject to any notes pertaining to unions. Open-ended piping with threaded or union connections shall be secured to prevent accidental rotation of the threaded joints. Tapered pipe threads may be used only in the following areas:

a. Connections to commercial equipment, such as washing machines and drinking water coolers, which are not essential to the ship under combat conditions and where failure would not create a hazard to personnel or the surrounding area, or affect the operation of other vital equipment.

b. Pipe plugs of a material compatible with the parent equipment material in sizes ¾ inch and below used for applications where gauge pressures do not exceed 50 psi.

c. Instrumentation, controls, vents and filling, and drain connections for applications where gauge pressures are 50 psi and below where fluids handled are neither toxic or dangerous nor could cause atmospheric contamination and which would not cause, in the event of failure, a major breakdown of the equipment, create a hazard to the surrounding area, nor affect the operation of other vital equipment.

d. For equipment where taper pipe threads are specified in RR-C-901, A-A-59860, MIL-V-17360, ASTM F1347, MIL-H-17902, and MIL-DTL-24788.

e. In unpressurized connections. f. Quick disconnect couplings for air hose connections and spray heads for washdown countermeasure

systems, magazine sprinkling, and wet sprinkling systems. g. Male NPT to 37-degree flare adapter fittings in accordance with SAE-J514 (3-piece assembly including nut,

sleeve, and tube) used for pneumatic (air) connection of control components to signal lines (125 psi maximum), where materials and fittings are specifically approved.

4.14 Fire-hardened fittings. Fire-hardened fittings are defined as fittings which are welded, or which comply with ASTM F1387, including satisfactory accomplishments of fire testing, and are approved by NAVSEA for the intended application. Where categories and groups have been combined from previous revisions of this standard as reflected in 5.3, only one designation from those combined categories/groups will be identified in table I and table II.

4.14.1 Fire-hardened fitting requirements. Fire-hardened fittings are required in the systems listed in table I below, where piping is located within compartments which are served by CO2 fixed flooding or Halon 1301 fire extinguishing systems.

Belled-end fittings in accordance with Manufacturer’s Standardization Society (MSS) SP-119, with the exception of couplings, are approved for systems defined by S9074-AR-GIB-010/278 as P-2 piping. Requirements and limitations for the fabrication, installation, welding, and system analysis are defined in S9AA0-AB-GOS-010, Section 505. Use of couplings to MSS SP-119 is approved based on mandatory supplemental and installation requirements defined in S9AA0-AB-GOS-010, Section 505.

4.48 Commercial item requirements. Use of special or commercial items not covered by this schedule and for items where the material or applicable document contains the word “commercial”, or has not been designated, shall be subject to approval by the cognizant SUPSHIP or NAVSEA.


MIL-STD-777F(SH)

24

4.48.1 Commercial plumbing material. For piping designed and routed in accordance with applicable ship specifications, commercial plumbing fittings, excluding PVC, are permitted downstream of a piping cutout valve in washrooms and in plumbing applications in spaces serviced by deck drains. Fittings shall be in accordance with ASME A112.18, or as approved.

4.49 Relief valves.

4.49.1 MIL-V-20065 relief valves. MIL-V-20065 relief valves shall be modified as follows:

a. In table I for discs and seat rings in columns for compositions A, B, and D, change “ASTM A276” to read “ASTM A276 or ASTM A479/A479M.”

4.49.2 MIL-V-24332 relief valves. MIL-V-24332 relief valves shall be modified as follows:

a. In table I for discs, seat rings, and stems in columns for Grades A and B, change “ASTM A276” to read “ASTM A276 or ASTM A479/A479M.”

b. Gaskets to be in accordance with system categories specified herein.

4.50 Stainless steel piping. Where ASTM A312/A312M is identified as an alternative to MIL-P-24691, the intergranular corrosion and flattening tests of MIL-P-24691/3 are invoked. Where stainless piping is specified, minimum thickness shall be Sch 10S.

4.51 Valve actuators. Valve electric actuators shall be in accordance with DOD-V-24657.

5. DETAILED REQUIREMENTS

5.1 Service categories and groups. Detailed requirements for piping systems are provided herein in tables arranged by service category and piping system groups. In general, service categories refer to the types of fluids handled, while system groups are designated according to piping pressure and temperature requirements. For example, the table for Category Group G-1 provides detailed requirements for all piping in the first system group (3000 psig, 180 °F, hydraulic service) of Category G (hydraulics).

5.2 Using the tables. For each service category and group, the reference to maximum systems for pressure and temperature is not meant to infer that only systems with these conditions are applicable to the category and group; only that the components and materials identified are suitable up to these maximum conditions, unless notes within a category and group identify other limitations. The contractor or installing activity shall be responsible for matching system requirements as closely as possible with the applicable category and group.

5.3 Category and group listing. The list below identifies the category and group combinations whose requirements are tabulated in this standard. The “date” column shows the date of the most recent update or change for each table. Category and groups have been combined from previous revisions of this standard as shown below. Where requirements are specified for a single category and group, they shall apply to all of the category/groups within that combined group.

INDEX

Since operating conditions may vary among different designs of ships, this index often refers to a category of materials only for each system. Within each category, selection should be made of that group which can accommodate the specific operating conditions of pressure and temperature for the system under consideration. (Example: Where the category only is specified such as “A”, the proper group, that is A-1, A-2, and so forth, shall be selected according to the operating conditions.)
