ASTM A193
Scope
Pakutanga yakatenderwa muna 1936, chirevo ichi chinoshandiswa zvakanyanya mu petroleum nemakemikari ekuvaka maapplication. Iyo ASTM yakajairwa inovhara alloy simbi uye Stainless simbi bholting zvinhu zvepamusoro tembiricha sevhisi. Izvi zvinosanganisira zvisungo zvakagadzirirwa kushandiswa mumidziyo yekumanikidza, mavharuvhu, maflange, uye mafittings. Nyangwe, chinhu ichi chinowanzo kuwanikwa mushinda dzepasirese (UNC) shinda, kana ichishandiswa mumashandisirwo echinyakare, shinda dzinotsanangurwa 8 shinda painch (tpi) yemadhayamita pamusoro peinji imwe.
Pazasi pane pfupiso yekutanga yeashoma emagiredhi akajairika. ASTM A193 inovhara akati wandei mamwe akajairwa zvirevo zvisina kufukidzwa mune ino tsananguro inosanganisira B5, B6, uye B16.
