Longitudinal welded kav
Khoom Taw Qhia
Longitudinal welded steel kav uas feem ntau yog cais raws li cov ntaub ntawv uas lawv tau tsim los ntawm, lawv npaj siv, thiab cov qauv lawv ua raws. Nquag, cov kav ntev welded steel kav uas xa mus rau cov qauv thiab kev faib tawm rau Submerged-Arc Welded Steel Pipes.
Cov qauv siv:
Longitudinal welded steel kav yuav raug cais raws li cov khoom uas lawv tau ua los ntawm, xws li carbon steel, stainless hlau, alloy steel, thiab lwm yam. Txhua yam khoom siv nrog nws tus kheej txheej txheem thiab specifications.
Cov qauv tsim khoom:
Cov txheej txheem tsim khoom ntawm Submerged-Arc Welded Steel Pipes tuaj yeem ua raws li cov qauv tshwj xeeb uas tau teev tseg los ntawm cov koom haum xws li American Petroleum Institute (API), American Society for Testing and Materials (ASTM), lossis lwm lub koom haum hauv teb chaws lossis thoob ntiaj teb cov qauv raws li hauv qab no: API 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB / T3091, GB / T9711, EN10217, EN10219
