Tlhahiso
Di-fitting tsa ASTM A234 tsa tšepe ea khabone li ka etsoa ka liphaephe tse se nang moedi, liphaephe tse phuthetsoeng kapa lipoleiti ka ho etsa mesebetsi ea ho hatella, ho phunya, ho ntša, ho koba, ho kopanya welding, ho sebetsa ka machining, kapa ka motsoako oa mesebetsi ena e 'meli kapa ho feta. Li-weld tsohle ho kenyeletsoa le li-weld lihlahisoa tsa tubula tseo li-fitting li entsoeng ho tsona li tla etsoa ho latela ASME Karolo ea IX. Kalafo ea mocheso oa kamora ho tjheseletsa ho 1100 ho isa ho 1250°F[595 ho isa ho 675°C] le tlhahlobo ea radiographic e tla etsoa kamora ts'ebetso ea ho tjheseletsa.
