MATERIALS
01.
PIPES
Dimensions from carbon steel pipes are defined in the ASME B36.10 standard, dimensions for stainless steel pipe are defined in the ASME B36.19 standard. The material qualities for these pipes are defined in the ASTM standards.
ASTM Materials
- A106 = This specification covers carbon steel pipe for high-temperature service.
- A335 = This specification covers seamless ferritic alloy-steel pipe for high-temperature service.
- A333 = This specification covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures.
- A312 = Standard specification for seamless, straight-seam welded, and cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.
02.
FITTINGS
Dimensions, from wrought carbon and alloy steel fittings are defined in several ASME standards. The material qualities for these fittings are defined in the ASTM standards.
ASTM Materials
- A234 = This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction.
- A420 = Standard specification for piping fittings of wrought carbon steel and alloy steel for low-temperature service.
- A403 = Standard specification for wrought austenitic stainless steel piping fittings.
03.
VALVES
ASTM Materials
- A216 = This specification covers carbon steel castings for Valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding.
- A217 = This specification covers steel castings, martensitic stainless steel and alloys steel castings for Valves, flanges, fittings, and other pressure-containing parts intended primarily for high-temperature and corrosive service.
- A352 = This specification covers steel castings for Valves, flanges, fittings, and other pressure-containing parts intended primarily for low-temperature service.
- = This specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and Valves and parts for high-temperature service.
04.
BOLTS & NUTS
ASTM Materials
- A193 = This specification covers alloy and stainless steel bolting material for pressure vessels, Valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications.
- A320 = Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for Low-Temperature Service.
- A194 = Standard specification for nuts in many different material types.
