API 5L:Cov qauv no yog tsim los ntawm American Petroleum Institute thiab qhia txog cov kev cai rau kev tsim cov kab yeeb nkab siv rau kev xa cov roj, roj, thiab lwm yam khoom siv roj av. Kev ua raws li API 5L ua kom ntseeg tau tias LSAW steel yeeb nkab ua tau raws li qhov tsim nyog thiab kev ua tau zoo rau kev siv hauv kev lag luam roj thiab roj.
ASTM A53 Cov Lus Qhia:ASTM A53 yog tus qauv tshwj xeeb rau cov yeeb nkab, hlau, dub thiab kub-dipped, zinc-coated, welded, thiab seamless. Ua raws li ASTM A53 kom ntseeg tau tias LSAW steel yeeb nkab ua tau raws li cov kev cai tshwj xeeb rau kev siv tshuab thiab kev siv siab, nrog rau kev siv dav dav.
ASTM A252 Cov Lus Qhia:tus qauv specification rau welded thiab seamless steel yeeb nkab pawg. Thaum nws los txog rau LSAW (Longitudinal Submerged Arc Welded) cov kav dej steel, kev ua raws li ASTM A252 yog qhov tshwj xeeb rau cov ntawv thov uas muaj cov yeeb nkab steel siv hauv kev tsim kho thiab kev txhawb nqa cov haujlwm. ASTM A252 qhia txog cov txheej txheem kev cai rau cov yeeb nkab steel, suav nrog qhov ntev, cov khoom siv kho tshuab, thiab cov txheej txheem kuaj.
LSAW steel kav uas ua tau raws li ASTM A252 yog tsim los ua kom tau raws li cov kev cai tshwj xeeb rau kev siv hauv kev siv piling, xws li kev tsim kho hauv paus, cov qauv hauv hiav txwv, kev tsim kho choj, thiab lwm yam kev tsim vaj tse. Ua raws li ASTM A252 kom ntseeg tau tias LSAW steel kav ua tau raws li qhov tsim nyog, kev ua tau zoo, thiab cov qauv kev nyab xeeb rau lawv cov kev npaj siv hauv kev siv piling.
