ASTM A335 He paipa mo te kawe paipa kohu
Ko te ASTM A335 Pipe Seamless, he momo ngongo rino korekore, he nui ake te mahi i te ngongo maitai whanui, na te mea he nui ake te Cr o tenei momo ngongo rino, he nui ake te Cr, tona parenga teitei, te iti o te pāmahana, te aukati waikura he iti ake i era atu. ngongo maitai tuitui, no reira ka whakamahia nuitia te ngongo koranu ki te hinu, matū, hiko hiko, kohua me etahi atu ahumahi.
ASTM A335 Paipa Korekore, Ko nga huānga ko te silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, konumohe, parahi, boron, whenua onge me etahi atu.
ASTM A335 Paipa Kore, He takai rino roa me te waahanga tuwhera, kaore he tuitui a tawhio noa.Ko te putorino rino he waahanga tuwhera, he nui te whakamahi mo te kawe i nga paipa wai, penei i te kawe hinu, hau maori, hau, wai me etahi mea totoka.Ko te putorino maitai tuitui me te rino porowhita me etahi atu rino totoka, i roto i te flexural me te torsional kaha i te wa ano, he mama ake te taumaha, he ahua o te wahanga ohaoha maitai, e whakamahia nuitia ana i roto i te hanga o nga waahanga hanganga me nga waahanga miihini, penei i te hinu. te kawe waka, te arai o te arawhata, te anga paihikara me te hanga i te raima rino.Ko te hanga i nga waahanga whakakai me te koranu putorino maitai ka taea te whakapai ake i te tere o te whakamahi rauemi, te whakangawari i te mahi hangahanga, te penapena rauemi me te waa tukatuka, penei i te whakakai whakakai, te ringaringa jack, me etahi atu, kua whakamahia nuitia ki te hanga paipa maitai.Ko te putorino maitai tuitui ranei nga momo patu tikanga katoa he mea tino nui, oko, oko me etahi atu ki te putorino maitai ki te hanga.Hei taapiri, ko te waahanga annular i raro i te pehanga radial o roto, o waho ranei, he nui ake te ahua o te kaha, na reira, ko te nuinga o nga ngongo maitai koranu he porotaka.
ASTM A335 Paipa Korekore, Te Tukatuka Whakaputa
Te okeoke wera (te ngongo maitai karehia) : pire ngongo porowhita → whakawera → perforation → toru-roll cross okeoke, te huri haere tonu, te tangohanga ranei → te tihorea ngongo → te rahinga (whakaiti ranei) → te whakamahana → te ngongo tuwhera → te whakatikatika → te whakamatautau pehanga wai (he hapa ranei kitea) → tohu → rokiroki.
Ko te tuhi matao (te huri) ngongo maitai kore: pire ngongo porowhita → whakawera → perforation → pane → annealing → pickling → hinu (te whakakikorua parahi) → te tuhi matao-maha (te hurihuri makariri) → ngongo parakore → te whakamahana wera → te whakatikatika → te whakamatautau pehanga wai (kitenga hapa) → tohu → rokiroki
