API 5Lte tikanga e pā ana ki te paipa maitai paipa (paipa paipa) o te whakatinanatanga o te paerewa, paipapaipa maitaitae atu ki te paipa maitai kore-tuinga me te paipa maitai whakarewa e rua ngā kāwai. I tēnei wā, i roto i te paipa hinu, he paipa maitai whakarewa momo paipa whakarewa porowhita-uru-pōro (SSAW), paipa whakarewa pewa i raro i te wai he hononga tika (LSAW), paipa whakarewa ātete (ERW), paipa maitai kore-tuituie whakamahia whānuitia ana mō te diameter o te paipa iti iho i te 152mm.
Ko te paerewa ā-motu o te paipa maitai GB/T 9711-2011 mō te pūnaha kawe paipa i roto i te umanga hinu me te hau, kua whakahiatohia kia rite ki te API 5L.
E whakamārama ana te GB/T 9711-2011 i ngā whakaritenga hanga mō ngā paipa rino kore hononga me ngā paipa whakarewa o ngā taumata whakatakotoranga hua e rua (PSL1 me PSL2) mō ngā pūnaha kawe paipa i roto i te umanga hinu me te hau. Nō reira, ka pā anake te paerewa ki ngā paipa rino kore hononga me ngā paipa rino whakarewa mō te kawe hinu me te hau, ā, kāore e pā ki ngā paipa rino maka.
