Product Name : Hastelloy B2 N10665 90 Elbow, 45 Elbow (SPP/SGP, 7.9T, STD, X-S) Wrought Carbon Steel Butt Weld Pipe Fittings

ANSI, MSS, ASME and CSA Standards

ASME/ANSI and MSS standards govern fitting dimensions and tolerances, ASME/ANSI B16.9 “Wrought Steel Buttwelding Fittings”, is the basic standard.

It covers steel butt-welding fittings sizes NPS 1/2 through NPS 48 (DN 15 through DN 1200).

Other ASME/ANSI and MSS standards, written to supplement B16.9, are as follows:

ASME/ANSI B16.25: Butt-welding Ends
ASME/ANSI B16.28: Butt-welding short radius elbows and returns
MSS SP-43: Light-wall stainless steel fittings, NPS 3/4 through NPS 24 (DN 20 through DN 600)
MSS SP-75: High Test Wrought Welding Fittings
The following codes and standards influence the manufacture of welding fittings, where applicable.
ASME/ANSI B31.1: Power piping
ASME/ANSI B31.3: Petroleum refinery piping
ASME/ANSI B31.4: Liquid petroleum transportation piping system
ASME/ANSI B31.5: Refrigeration piping
ASME/ANSI B31.8: Gas transmission and distribution piping systems
ANSI/ASME B36.10M: Welded and seamless wrought steel pipe
ANSI/ASME B36.19M: Stainless steel pipe
CSA Z183: Oil pipe line transportation systems
CSA Z184: Gas pipe line systems
CAN3-Z245.11-M91: Requirements for wrought steel butt welding fittings
ASME: Boiler and pressure vessel code
