API 5L X70 (L485)he momo paipa rino e whakamahia ana i roto i te umanga hinu me te hau mō ngā pūnaha kawe paipa, i tapaina i muri i tōna iti rawakaha whakaputa o te 70,300 psi (485 MPa), ā, he paipa tuimotu, he paipa whakarewa hoki, ā, e wehea ana kia rua ngā taumata whakatakotoranga hua, ko PSL1 me PSL2. I roto i te PSL1, ko X70 te taumata teitei rawa atu, i roto i te PSL2 ko tētahi o ngā taumata teitei ake o te paipa maitai.
He tino pai te paipa maitai API 5L X70 mō ngā hiahia o te kawe tawhiti, te pehanga teitei nā te mea he kaha teitei me te ātete ki te pehanga. Hei tu atu i ngā pehanga teitei ake, he maha ngā wā ka hangaia te paipa maitai X70 me ngā pakitara matotoru hei whakarite i te kaha me te roa o te mau.

Ngā Tikanga Tukunga
Ko te āhua tuku ko te āhua o te ngongo maitai kua tukatukahia, kua tukatukahia rānei ina rite ki te tuku ki te kaihoko i muri i te hanga. He mea nui te āhua tuku kia mau ai te ngongo i ngā āhuatanga miihini me te hanganga e hiahiatia ana.
I runga i te taumata PSL me te āhua tuku, ka taea te whakarōpū i te X70 penei:
PSL1: X70 (L485);
PSL2: X70Q (L485Q) me X70M (L485M);
Ko ngā reta whakamutunga PSL2 Q me M e tohu ana i ēnei:
QKua tineia, kua whakamahanatia;
M: He mea hurihuri, he mea hanga rānei i roto i te āhua wera;
Tukanga Hanganga e Manakohia ana mō te API 5L X70
Kei roto i te tukanga hanga X70 ngā mea e ruahe kore hononga, he mea whakarewangā puka, ka taea te whakarōpū hei:
O ēnei,SAWLKo te LSAW (LSAW) te tukanga tino noa e whakamahia ana i roto i te hanga o ngā tukanga whakarewa X70, ā, he painga hoki i roto i te hanga o ngā paipa maitai he whānui nui, he pakitara matotoru.
Ahakoa e kiia tonu ana ko ngā paipa rino tuimotu te mea pai rawa atu nā ō rātou āhuatanga i raro i ētahi āhuatanga tino kino, ko te whānui mōrahi o ngā paipa rino tuimotu e hangaia ana he 660 mm te nuinga o te wā. Ka raru pea tēnei herenga rahi ina pāngia e ngā kaupapa paipa kawe waka nui tawhiti.
He rerekē, ka taea e te tukanga LSAW te whakaputa ngongo tae atu ki te 1,500 mm te whānui me te matotoru o te pakitara tae atu ki te 80 mm. Ā, he iti ake te utu i te maitai kore hononga.
