pipe fitting
ASTM A234 is a standard specification for steel pipe fittings, including carbon and alloy steel materials for medium and high temperature service. It covers seamless and welded types of steel fittings. Steel pipe fittings are used in the manufacture of pressure pipes and pressure vessels. These fitting materials include killed steel, forgings, bar, sheet, seamless or HFW (fusion welded) pipe products with added filler metals.
