LSAW (Longitudinal Submerged Arc Welded) chitsulo chitoliro ndi mtundu wa welded zitsulo chitoliro kuti amapangidwa pogwiritsa ntchito kumizidwa arc kuwotcherera ndondomeko.

API 5L:Muyezo uwu wakhazikitsidwa ndi American Petroleum Institute ndipo umatchula zofunikira popanga chitoliro chomwe chimagwiritsidwa ntchito potengera mafuta, gasi, ndi zinthu zina zamafuta. Kutsatira API 5L kumatsimikizira kuti chitoliro chachitsulo cha LSAW chikukwaniritsa zofunikira zoyenera komanso zogwirira ntchito zomwe zimagwiritsidwa ntchito pamakampani amafuta ndi gasi.
ASTM A53:ASTM A53 ndi muyezo wa chitoliro, chitsulo, chakuda ndi choviikidwa choviikidwa ndi zinki, chotenthetsera, komanso chopanda msoko. Kutsatira ASTM A53 kumawonetsetsa kuti chitoliro chachitsulo cha LSAW chikukwaniritsa zofunikira zomwe zimagwiritsidwa ntchito pamakina ndi kukakamiza, komanso kugwiritsidwa ntchito wamba.
ASTM A252:ndondomeko yokhazikika ya milu yowotcherera ndi yopanda msoko. Zikafika ku LSAW (Longitudinal Submerged Arc Welded) mapaipi achitsulo, kutsatira ASTM A252 ndikofunikira makamaka pamapulogalamu okhudzana ndi milu yachitsulo yomwe imagwiritsidwa ntchito pomanga ndi ma projekiti othandizira. ASTM A252 imatchula zofunikira zaukadaulo pamilu yazitsulo zachitsulo, kuphatikiza miyeso, mawonekedwe amakina, ndi njira zoyesera.
Mapaipi achitsulo a LSAW omwe amatsatira ASTM A252 adapangidwa kuti akwaniritse zofunikira zomwe zimagwiritsidwa ntchito pomanga mulu, monga kumanga maziko, nyumba zam'madzi, kumanga mlatho, ndi ntchito zina zama engineering. Kutsatira ASTM A252 kumawonetsetsa kuti mapaipi achitsulo a LSAW amakwaniritsa zofunikira, magwiridwe antchito, ndi miyezo yachitetezo kuti agwiritse ntchito pomanga mulu.
