Ko te API 5L e pā ana ki te paerewa whakatinanatanga mō ngā paipa maitai, e rua ngā wāhanga matua:ngā paipa maitai kore honongamengā paipa maitai kua whakarewainaI tēnei wā, ko ngā momo paipa maitai whakarewa e whakamahia whānuitia ana i roto i ngā paipa hinu kongā paipa whakarewa porowhita i raro i te wai(Paipa SSAW),ngā paipa whakarewa pewa roa e rukuhia ana ki raro(Paipa LSAW), me tengā paipa whakarewa ātete hiko(ERW). Ko ngā paipa rino kore-tuitui ka tīpakohia i te nuinga o te wā ina iti iho te diameter o te paipa i te 152mm.
I whakawhanakehia te paerewa ā-motu GB/T 9711-2011, arā, Ngā Paipa Rino mō ngā Pūnaha Kawe Paipa i roto i ngā Ahumahi Hinu me te Hau Taiao, i runga i te API 5L.
E whakamārama ana a GB/T 9711-2011 i ngā whakaritenga hanga mō ngā paipa rino kore hononga me ngā paipa whakarewa e whakamahia ana i roto i ngā pūnaha kawe paipa hinu me te hau māori, e kapi ana i ngā taumata whakatakotoranga hua e rua (PSL1 me PSL2). Nō reira, e pā ana tēnei paerewa ki ngā paipa rino kore hononga me ngā paipa whakarewa mō te tuku hinu me te hau, ā, kāore e pā ki ngā paipa rino maka.
Ngā Tohu Rino
Ka whakamahia e ngā paipa maitai API 5L ngā momo rauemi mata tae atu ki te GR.B, X42, X46, X52, X56, X60, X70, X80, me ētahi atu. Kua whakawhanakehia ngā maitai paipa me ngā tohu X100 me te X120. He rerekē ngā whakaritenga mō ngā rauemi mata me ngā tukanga whakaputa e hiahiatia ana e ngā momo maitai rerekē.
Ngā Taumata Kounga
I roto i te paerewa API 5L, ka whakarōpūtia te kounga maitai o te paipa hei PSL1, hei PSL2 rānei. Ko te PSL he whakarāpopototanga mō te Taumata Whakatakotoranga Hua.
E whakamārama ana a PSL1 i ngā whakaritenga kounga whānui mō te maitai paipa; e tāpiri ana a PSL2 i ngā whakaritenga ā-ture mō te hanganga matū, te pakari o te kohao, ngā āhuatanga kaha, me ngā whakamātautau NDE tāpiri.
