Tukanga Hanga o ASTM A213 Alloy Seamless Steel Tubes

ASTM A213 koranu ngongo maitai tuitui ka hangaia ma te kumea-matao, ma te wera ranei i hurihia, pera i tohua.Ko te karaehe TP347HFG ka mutu te makariri.Ko te maimoatanga wera me mahi motuhake me te taapiri atu ki te whakamahana mo te hanga wera.Me whakamahana ano te koranu ferritic me nga tira kowiri tira.I tetahi atu taha, ka tukuna nga ngongo kowiri tira austenitic i roto i te ahua o te wera.I tua atu, i muri tonu i te wera o te hanga, ahakoa ko te pāmahana o nga ngongo e kore e iti iho i te iti rawa o te pāmahana otinga, ka tineia takitahi nga ngongo ki roto i te wai, ka tere te whakamatao ma etahi atu tikanga.
