43、PF-Pl-0001.6.2FITTINGS REQUIREMENTSFitting material selection and identification shall be accomplished with the selection of a piping specification.6.3TEMPERATURE AND PRESSURE RANGESThe rated conditions for a piping specification are generally based on the pressure ratings of the included flanges (p

44、ressure Class and material) for a desired temperature range. The rated conditions will equal or exceed the design conditions for any piping service which utilizes the specification. Specification condition ranges are selected to utilize a material group without significantly increasing the cost of t

45、he components for any application. Flange pressure ratings are extracted from ASME B16.5 /A SME B16.47 for 150, 300, 600, 900, 1500 and 2500 class systems. For the pressure rating of 3000 and 5000 Psi, API 6A should be followed.For service design conditions, Maximum temperatures for any specificatio

46、n will be selected to at least equal the highest design temperature expected for a service utilizing the material group.6.4BOLTINGBolting materials specified for all piping specifications are according to applicable standards and design temperature ranges. Bolting material ratings are based on un-in

47、sulated Connections.Bolt dimensions are not included in this specification. Bolts dimension shall be in accordance with ASME B16.5 / ASME B16.47 / MSS SP - 44 and API 6A for all standard flanges.SPECIFICATION FOR PIPING MATERIALPage 10 of 38NPS1/2 TO 34 AND LARGERMin.
