24590 PAW WOO41 Rev 5 6 28 2004, 24590 WTP PER PL 02 001 Rev 6. Piping Material Class Description, 1 Introduction, This document describes the minimum requirements for the piping material classes for the River. Protection 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 to. specific fluid service The piping classes apply to bulk piping components and do not cover specialty. items identified on engineering data sheets, 2 Applicable Documents. 2459O WTP 3PS GOOO TPOO2, Positive Material Identification PMI. 3 Description, Appendix A summarizes the requirements in the piping material classes Piping regulated under the.
Dangerous Waste Permit is identified on permit drawings All piping classes are shown in this document. for completeness The following general guidelineshequirements are considered in the development of. the piping material classes, The applicable design code s is as noted on the piping material class summary Appendix A Any. conflicts between this document and the applicable design codes shall be brought to the attention of the. RPP WTP piping engineering group of the plant design discipline. 3 2 Pipe Wall Thickness and Branch Reinforcements, The specific pipe thickness or schedule number is supported by a wall thickness calculation and if. necessary by a branch reinforcement calculation Any increases in the design conditions used as the. basis of these piping class sheets must be supported by a revision to the wall thickness calculation or by. additional calculation, The commercially available pipe wall thickness specified in the piping class sheets meet or exceed the. minimum calculated wall thickness, Integrally reinforced branch connections do not require a separate calculation The branch reinforcement. for all non integrally reinforced shall be supported by a branch reinforcement calculation. 3 3 Design Conditions, The service limits and the corrosioderosion allowance referred to in the piping material class summary.
are enveloping conditions Pressures and temperatures listed shall not be exceeded except as permitted by. the applicable code, 24590 PADC FOOO41 Rev 5 6 28 2004. 24590 WP PER PL 02 001 Rev 6, Piping Material Class Description. Nominal pipe sizes NPS A 1 1 A 2 3 5 and 22 and any other nominal pipe size not shown in. ASME B36 10 B36 19 should not be used except to match manufacturer s equipment connections or as. specified on the P IDs Where necessary to match a manufacturer s equipment connection a transition. piece must be employed immediately adjacent to the equipment for the transition to the next acceptable. In general all N P S 2 and larger pipe with a schedule of standard weight and heavier has been specified as. double random length and NPS 1 h and smaller as single random length The majority of pipe included in. these classes is multiple stamped, Seamless API SL Gr B ASTM A106 Gr B and A53 Gr B or ASTM A312 TP 304 304L or ASTM. A312 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 stainless. steel have been used to provide enhanced mechanical strength. 3 5 Flanges, NPS 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 diameter. water lines, Orifice flanges shall be in accordance with ASME B16 36 and shall be supplied in pairs complete with. jackscrews but without bolts gaskets or orifice plates Quantities on bill of material material. requisitions etc shall indicate sets not individual flanges. Blanks either permanent of temporary are required to have sufficient thickness per the ASME B3 1 3. Code Spectacle blinds in accordance with ASME B16 48 shall not be used as permanent blanks and. shall be used only where required to isolate line for pressure testing start up or maintenance Gasket. contact surface finishes shall be the same as the mating flanges. 3 6 Fittings, Buttweld fittings shall conform to the material requirements and wall thickness of the pipe with which. they are used, The wall thickness of reducing tees concentric and eccentric reducers shall correspond on each end to the. wall 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. 24590 PAW WOO41 Rev 5 6 28 2004, 24590 WP PER PL 02 001 Rev 6.
Piping Material Class Description, 3 7 Bolting and Gaskets. Machine 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 from. the 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 or. B 16 47 as applicable and referenced in piping material class as a bolt table Bolt tables do not include. increased 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 for. every bolthole Cap screws shall be threaded full length The length shall be measured from the bearing. surface of the head and shall include the end point. 3 8 Valves, Valves specified to be drilled and tapped for drain connections body cavity vents etc shall be supplied. with the tapped holes fitted with solid square head pipe plugs of the same basic material as the valve. body 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 anti. static devices fitted in accordance with API 608, Butterfly valves are used for positive shutoff in sizes 10 inch and larger Wafer type butterfly valves have. been 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 end. application 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 accordance. with API 607, Typical gear operated valve sizes, Gate Valves.

Classes 1500 and 2500 NPS 4 and Larger, Butterfly Valves. Classes 150 and 300 NPS 10 Larger, Classes 600 and 900 NPS 6 Larger.
Classes 1500 and 2500 NPS 6 Larger, Ball and Plug Valves. 24590 PADC F00041 Rev 5 6 28 2004, 24590 WP PER PL 02 001 Rev 6. Piping Material Class Description, Classes 150 and 300 NPS 8 Larger. Classes 600 and 900 NPS 6 Larger, Classes 1500 and 2500 NPS 4 Larger. Additionally gear operators may be required on specific valves to satisfy process operational and or. other requirements, 3 9 Method of Construction, Basically the method of construction is as follows.
Shop fabricated carbon steel NPS 1 4and smaller pipe are socket welded while NPS 2 and larger. are butt welded construction, Shop fabricated stainless steel NPS 1 pipe and smaller are socket welded while NPS 1 4 and. larger are butt welded, The small bore valves are socket welded up to size N P S 2 for both cases. Field fabrication for carbon and stainless steel piping NPS 2 and smaller should be socket weld. Certain piping material classes in this document are required to be all butt weld construction based on the. service requirements, 3 10 Branch Connection, The branch connection fittings are specified in the piping material class branch tables. 3 1 1 Corrosion Allowance, Corrosion allowance as used in pipe classes includes erosion For pipe class W62F 0 01 6 corrosion. erosion allowance is used to match the interface piping. 3 12 Positive Material Identification PMI, Document 2459O WTP 3PS GOOO TP002 defines the requirements for Positive Material Identification.
Piping Material Class Description 3 4 Pipe Nominal pipe sizes NPS A 1 1 A 2 3 5 and 22 and any other nominal pipe size not shown in ASME B36 10 B36 19 should not be used except to match manufacturer s equipment connections or as specified on the P amp IDs Where necessary to match a manufacturer s equipment connection a
