1. Scope*

These dimensions are also applicable to heavily cold workedpipe. Pipe having other dimensions is permitted to be orderedand furnished provided such pipe plies with all other requirements of this specification.

1.1 This specification² covers seamless straight-seamsteel pipe intended for high-temperature and general corrosive welded and heavily cold worked welded austenitic stainless service.

For example Grades TP304 TP304L and TP347 are accepted by the ASME Pressure VesselCode Section VII Division 1 and by the Chemical Plant and Refinery Piping Code ANSI B31.3 for service at temperatures as low as 425 °Fgrades are usually accepled fer service temperatures as low as 325 °F [200 °C] without impact testing. Impuct testing may under certain [250 °C] without qualification by impact tests. Other AISI stainless steelcircumstances be required. For example materials with chromium or nickel content outside the AISI ranges and for material with carbonof ASME Section VII Division’1 when service temperatures are lower content exceeding 0.10 % are required to be impact tested under the ruls[. s] 0s um
