API 5L:Nā te American Petroleum Institute tēnei paerewa i whakatakoto, ā, e tohu ana i ngā whakaritenga mō te hanga paipa raina e whakamahia ana mō te kawe hinu, hau, me ētahi atu hua hinu. Mā te tutuki i te API 5L ka tutuki i te paipa maitai LSAW ngā paearu kounga me te mahi e tika ana mō te whakamahi i roto i te umanga hinu me te hau.
ASTM A53:He paerewa te ASTM A53 mō ngā paipa, te maitai, te pango me te wera-toia, te paninga konutea, te whakarewa, me te kore hononga. Mā te tutuki i te ASTM A53 ka tutuki i te paipa maitai LSAW ngā whakaritenga motuhake mō te whakamahinga i roto i ngā tono miihini me te pēhanga, tae atu ki te whakamahinga whānui.
ASTM A252:he whakatakotoranga paerewa mō ngā puranga paipa rino kua whakarewaina me te kore hononga. Mō ngā paipa rino LSAW (Longitudinal Submerged Arc Welded), he mea nui te tutuki i ngā whakaritenga ASTM A252 mō ngā tono e pā ana ki ngā puranga paipa rino e whakamahia ana i roto i ngā kaupapa hanga me te tautoko hanganga. E whakamārama ana a ASTM A252 i ngā whakaritenga hangarau mō ngā puranga paipa rino, tae atu ki ngā ine, ngā āhuatanga miihini, me ngā tikanga whakamātautau.
Ko ngā paipa rino LSAW e tutuki ana i ngā whakaritenga ASTM A252 kua hangaia kia tutuki ai ngā whakaritenga motuhake mō te whakamahinga i roto i ngā mahi poupou, pērā i te hanganga turanga, ngā hanganga moana, te hanganga piriti, me ētahi atu kaupapa hangarau ā-iwi. Mā te tutuki i ngā whakaritenga ASTM A252 ka tutuki i ngā paipa rino LSAW ngā paerewa kounga, mahi, me te haumaru e tika ana mō te whakamahinga i roto i ngā mahi poupou.
