24590-WTP-PER-PL-02-001, Rev 6Piping Material Class Description1IntroductionThis document describes the minimum requirements for the piping material classes for the RiverProtection Project - Waste Treatment Plant. It summarizes the piping material requirements for pipe,fittings, flanges, valves, and all other piping components for each specific pipe class as applicable tospecific fluid service. The piping classes apply to bulk piping components and do not cover specialtyitems identified on engineering data sheets.2Applicable Documents2459O-WTP-3PS-GOOO-TPOO2,“Positive Material Identification (PMI)3DescriptionAppendix A summarizes the requirements in the piping material classes. Piping regulated under theDangerous Waste Permit is identified on permit drawings. All piping classes are shown in this documentfor completeness. The following general guidelineshequirements are considered in the development ofthe piping material classes.3.1CodesThe applicable design code(s) is as noted on the piping material class summary (Appendix A). Anyconflicts between this document and the applicable design codes shall be brought to the attention of theRPP-WTP piping engineering group of the plant design discipline.3.2Pipe Wall Thickness and Branch ReinforcementsThe specific pipe thickness or schedule number is supported by a wall thickness calculation and ifnecessary, by a branch reinforcement calculation. Any increases in the design conditions used as thebasis of these piping class sheets must be supported by a revision to the wall thickness calculation or byadditional calculation.The commercially available pipe wall thickness specified in the piping class sheets meet or exceed theminimum calculated wall thickness.Integrally reinforced branch connections do not require a separate calculation. The branch reinforcementfor all non-integrally reinforced shall be supported by a branch reinforcement calculation.3.3Design ConditionsThe service limits and the corrosioderosion allowance referred to in the piping material class summaryare enveloping conditions. Pressures and temperatures listed shall not be exceeded except as permitted bythe applicable code.Page 324590-PADC-FOOO41 Rev 5 (6/28/2004)

24590-WP-PER-PL-02-001, Rev 6Piping Material Class Description3.4PipeNominal pipe sizes (NPS) !A, 1/, %, 1!A, 2%, 3 %, 5 and 22, and any other nominal pipe size not shown inASME B36.10 / B36.19, should not be used except to match manufacturer’s equipment connections or asspecified on the P&IDs. Where necessary to match a manufacturer’s equipment connection, a transitionpiece must be employed immediately adjacent to the equipment for the transition to the next acceptablepipe size.In general, all N P S 2 and larger pipe with a schedule of standard weight and heavier has been specified asdouble random length and NPS 1!h and smaller as single random length. The majority of pipe included inthese classes is multiple stamped.Example:(Seamless API-SL Gr. B, ASTM A106 Gr. B and A53 Gr. B, or ASTM A312 TP 304/304L or ASTMA312 TP 316/316L).For carbon steel material by ASME B31.3, Para./ Fig. 323.2.2, impact testing may be required.Schedule 160 threaded pipe nipples for carbon steel and schedule 80s threaded pipe nipples for stainlesssteel have been used to provide enhanced mechanical strength.3.5FlangesNPS 24 and smaller steel flange dimensions and ratings are to ASME B 16.5.NPS 26 through NPS 60 steel flange dimensions and ratings are to ASME B 16.47 Series A. However,ASME B16.47 Series B may be used when needed to mate with existing equipment.Flat faced flanges shall be used to match flat face equipment and other flat faced flanged components(e.g., copper alloy, cast iron flanges, GRP flanges and for NPS 30 and larger flanges in large diameterwater lines).Orifice flanges shall be in accordance with ASME B16.36 and shall be supplied in pairs, complete withjackscrews, but without bolts, gaskets, or orifice plates. Quantities on bill of material, materialrequisitions, etc., shall indicate sets, not individual flanges.Blanks, either permanent of temporary are required to have sufficient thickness per the ASME B3 1.3Code. Spectacle blinds in accordance with ASME B16.48 shall not be used as permanent blanks andshall be used only where required to isolate line for pressure testing, start up or maintenance. Gasketcontact surface finishes shall be the same as the mating flanges.3.6FittingsButtweld fittings shall conform to the material requirements and wall thickness of the pipe with whichthey are used.The wall thickness of reducing tees, concentric and eccentric reducers shall correspond on each end to thewall thickness of the mating pipe.Half couplings shall not be used for branch connections in ASME B3 1.3 Piping Material Classes.Elbolets shall be used only where specifically allowed per the piping assembly details.Page 424590-PAW-WOO41 Rev 5 (6/28/2004)

24590-WP-PER-PL-02-001, Rev 6Piping Material Class Description3.7Bolting and GasketsMachine bolts shall not be used except as jackscrews and when bolting Cast Iron, Bronze, Ductile Iron,PVC, or Fiberglass flanges. Jackscrews shall be threaded full length. The length shall be measured fromthe bearing surface of the head and shall include the end point.Stud bolts shall be threaded full length. Length of stud bolts shall be in accordance with ASME B16.5 orB 16.47 as applicable, and referenced in piping material class as a bolt table. Bolt tables do not includeincreased lengths required for use with bolt tensioning and other non-standard components / equipment.Cap screws are used where the valve or component design does not allow through bolts to be used forevery bolthole. Cap screws shall be threaded full length. The length shall be measured from the bearingsurface of the head and shall include the end point.3.8ValvesValves specified to be drilled and tapped for drain connections, body cavity vents, etc., shall be suppliedwith the tapped holes fitted with solid, square head pipe plugs of the same basic material as the valvebody, in accordance with ASME B 16.14.If ball valves are required to be “Fire Safe” they shall be in accordance with API 607 and shall have antistatic devices fitted in accordance with API 608.Butterfly valves are used for positive shutoff in sizes 10 inch and larger. Wafer type butterfly valves havebeen specified for in-line service based on lower total installed and operation cost (TIC).Tapped lugged wafer type (e.g., butterfly, check, etc.) valves have been specified for dead endapplication, and when fitted between cast iron or non-metallic flanges.Unlined soft seated butterfly valves and plug valves, if required to be “Fire Safe” shall be in accordancewith API 607.Typical gear operated valve sizes:Gate ValvesClasses 150 and 300Classes 600 and 900Classes 1500 and 2500NPSNPSNPS14 & Larger8 & Larger8 & LargerGlobe and Angle ValvesClasses 150 and 300Classes 600 and 900Classes 1500 and 2500NPSNPSNPS12 & Larger6 & Larger4 and LargerNPS10 & Larger6 & Larger6 & LargerButterfly ValvesClasses 150 and 300Classes 600 and 900Classes 1500 and 2500NPSNPSBall and Plug ValvesPage 524590-PADC-F00041 Rev 5 (6/28/2004)

For pipe class W62F, 0.01 6" corrosion/erosion allowance is used to match the interface piping.3.12Positive Material Identification (PMI)Document 2459O-WTP-3PS-GOOO-TP002 defines the requirements for Positive Material Identification(PW.Page 624590-PADC-FOOD41 Rev 5 (6/28/2004)
