API 5L:Lo mgangatho umiselwe yi-American Petroleum Institute kwaye uchaza iimfuno zokwenza umbhobho womgca osetyenziselwa ukuhambisa ioli, igesi, kunye nezinye iimveliso ezisekelwe kwipetroleum. Ukuthotyelwa kwe-API 5L kuqinisekisa ukuba ipayipi yensimbi ye-LSAW ihlangabezana nomgangatho ofunekayo kunye neendlela zokusebenza zokusetyenziswa kwishishini leoli kunye negesi.
I-ASTM A53:I-ASTM A53 luphawu oluqhelekileyo lombhobho, intsimbi, emnyama kunye neshushu-dip, i-zinc-coated, i-welded, kwaye ingenamthungo. Ukuthotyelwa kwe-ASTM A53 kuqinisekisa ukuba umbhobho wensimbi we-LSAW uhlangabezana neemfuno ezithile zokusetyenziswa kumatshini kunye nezicelo zoxinzelelo, kunye nokusetyenziswa ngokubanzi.
I-ASTM A252:inkcazo esemgangathweni yeemfumba zemibhobho yentsimbi edityanisiweyo kunye nengenamthungo. Xa kuziwa kwi-LSAW (i-Longitudinal Submerged Arc Welded) imibhobho yensimbi, ukuthotyelwa kwe-ASTM A252 kubaluleke kakhulu kwizicelo ezibandakanya iimfumba zemibhobho yensimbi ezisetyenziselwa ukwakhiwa kunye neeprojekthi zenkxaso yezakhiwo. I-ASTM A252 ichaza iimfuno zobugcisa kwiimfumba zemibhobho yentsimbi, kubandakanywa imilinganiselo, iimpawu zomatshini, kunye neenkqubo zokuvavanya.
Imibhobho yentsimbi ye-LSAW ehambelana ne-ASTM A252 iyilelwe ukuhlangabezana neemfuno ezithile zokusetyenziswa ekufakeni izicelo, ezinjengokwakhiwa kwesiseko, izakhiwo zaselwandle, ukwakhiwa kwebhulorho, kunye nezinye iiprojekthi zobunjineli boluntu. Ukuthotyelwa kwe-ASTM A252 kuqinisekisa ukuba iipayipi zensimbi ze-LSAW zihlangabezana nomgangatho ofunekayo, ukusebenza, kunye nemigangatho yokhuseleko yokusetyenziswa ekujoliswe kuyo ekufakeni izicelo.
