Ko te tikanga, ko te API 5L e pa ana ki te API 5L raina paipa, kei waho o te whenua te hinu, te hau, te wai, ka haria e te paipa ki te paipa hinu me nga kamupene umanga hau.

kia rite ki te tukanga hanga me te puāwaitanga ngongo whakamahia ahua rerekē, ka taea te wehea api 5l ki te api 5l paipa maitai pai me te pai paiherea api putorino, i roto i te rahinga whakamahi o paiherea paipa maitai he nui atu i te putorino maitai tui.

Koeke paipa raina me nga waahanga matū

Ka taea te wehewehea te API 5L ki te API 5L PSL 1 me te API 5L PSL 2, tae atu ki te taumata API 5L PSL 1 me nga waahanga: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 taumata ā ko te kāwai ko B, x42, x46, x52, x56, x60, x65, xx70, x80.te teitei o te taumata ka kaha ake nga taonga miihini.

Te tono: whakamahia mo te ahumahi hinu me te hau, te hau, te wai, te kawe hinu.

API SPEC 5L Raina Paipa

API SPEC 5L tukanga whakaputa putorino raina kua wehea ki putorino maitai tui, ERW paipa maitai, ruku pewa paiherea putorino.Engari ko te whakamahinga matua o te putorino maitai (te Seamless), te tui torotika teitei te kaha o te atete ki te paipa maitai (Electric-Resistance Arc Welding, te whakapoto hei ERW), te LSAW (Longigudinally Submerged Arc Welding poto LSAW), te putorino paiherea arc submerged (Spirally). Welding Arc Submerged, poto o SSAW) wha.

LSAW paipa wehea ki UO (te tikanga hanga o UOE), RB (RBE), te JCO (JCOE) me etahi atu momo.Pereti maitai i roto i te niao e aki ki te U-ahua, a ka aki ki te O-, a ka te roto, me te waho te pewa fehokotaki'anga submerged, i muri i fehokotaki'anga, te tikanga i te mutunga o te roa tonu o te expander (Whakawhānui) huaina UOE paipa paiherea, e kore e whakaroa e mohiotia ana ko te paipa UO.Pressure maitai pereti pukapuka piko (Roll Bending), a ka te roto, me te waho arc fehokotaki'anga, i muri fehokotaki'anga, whakawhänui i te putorino RBE, ranei e kore e whakawhānui i te paipa RB.Pereti niao rite ki te momo JOC-ota whakawhänui JCOE putorino kore ranei whakawhänui JCO putorino i muri fehokotaki'anga.LSAW paipa i runga, te whakamahi o te UOE noa.Ko te nui o te kaha o te whakaeke i te ngongo ngongo ERW ngongo embryo na roto i te paanga o te kiri me te paanga tata i roto i nga waa teitei-nui ki te taha o te rewanga, katahi ka pehia nga roera i raro i te pehanga pehanga, e tohuhia ana e te kore whakarewa o waho, te wera wera rohe, teitei. te pai o te whakaputa.Paipa tui porowhita te SSAW mo te paipa raina tawhiti he roa te hitori, ko te paipa i Haina te nuinga o te whakamahi.
