L245 yog hais txog qib ntawm cov hlau siv hauv LSAW (Longitudinal Submerged Arc Welded) yeeb nkab. L245 yog qib API 5L tshwj xeeb, tshwj xeeb yog qib rau cov kab yeeb nkab. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 245 MPa (35,500 psi). LSAW welding txheej txheem cuam tshuam nrog qhov ntev vuam ntawm cov hlau phaj, thiab cov beveled xaus qhia tias cov yeeb nkab kawg raug txiav thiab npaj nrog beveled ntug kom yooj yim vuam. Qhov tshwj xeeb "xim dub" qhia tau hais tias sab nraud ntawm cov yeeb nkab yog coated nrog cov xim dub rau kev tiv thaiv corrosion thiab zoo nkauj.
