API 5L X70 raina paipa maitai

Ko te paipa API 5L X70 he taonga paipa paipa utu i roto i nga whakaritenga paerewa API 5L. Ka kiia hoki ko te paipa L485, na te mea he iti rawa te kaha o te tuku i te 485 Mpa (70,300 psi). Ko te API 5L X70 e hipoki ana i nga momo hangahanga i roto i nga momo maamaa me te paiherea (RW, SAW), e rua mo te tuku hinu me te hau.
Whakataki hua

Ko te paipa API 5L X70 he taonga paipa paipa utu i roto i nga whakaritenga paerewa API 5L. Ka kiia hoki ko te paipa L485, na te mea he kaha tuku
iti rawa i roto i te 485 Mpa (70,300 psi). Ko te API 5L X70 e kapi ana i nga momo whakangao i nga momo miihini me te paiherea (RW, SAW), ka whakamahia e rua.
mo te whakawhiti hinu me te hau.

API X70 waro waro raina putorino taea te tautuhi rite putorino maitai ki te ihirangi waro tiketike, me te alloying pūhui. API 5L X 70 waro maitai putorino tuitui I tua atu i te maha o etahi atu huānga penei i te whanariki, te ūkuikui, me etahi atu, he nui te konupora me te silicon o tona koranu. Ko te taapiri o enei waahanga katoa ka awhina ki te whakapai ake i nga ahuatanga miihini o te paipa maitai waro X70.

Ka kitea tenei mai i te iti o te kaha tuku (485 MPa) o te ngongo API 5L X70 Class B LSAW. He 635 MPa te iti rawa o te kaha tensile. Ko te mata o te API 5L X70 SCH 40 DSAW ngongo e rongoahia ana i roto i nga momo rereke, penei i te pango, te hinu anticorrosive, te wera-wera, te makariri ranei. I runga i te whakamahinga motuhake o te ngongo torino X70 PSL2, ka taea e matou te taunaki i te maimoatanga mata pai mo o taatau kaihoko rangatira. Hei tauira, ko te paninga piauau i runga i nga putorino karaehe X70 PSL1 e whakaatu ana i te tino pai o te aukati waikura.
