ASTM A53 Paipa maitai
Ko te ASTM A53 (ASME A53) te putorino waro waro he tohu e hipoki ana i te paipa pango me te paiherea pango me te wera-wera piauau piauau putorino i roto i te NPS 1/8″ ki te NPS 26. Ko te 53 te tikanga mo te pehanga me te whakamahi miihini me te pai hoki mo nga mea noa. whakamahia i roto i te mamaoa, te wai, te hau, me nga raina hau.
E toru nga momo paipa A53 (F, E, S) me nga tohu e rua (A, B).
Ko te A53 Momo F he mea hanga ki te weriweri reke oumu, ka mau tonu ranei te paihere (Koeke A anake)
A53 Momo E he paihere parenga hiko (Koeke A me B)
Ko te A53 Momo S he paipa korekore, ka kitea i nga Koeke A me B)
Ko te A53 Grade B Seamless to tatou hua tino polar i raro i tenei whakakitenga me te paipa A53 he tohu takirua ki te putorino A106 B Seamless.
