API kab yeeb nkab yog cov kab yeeb nkab uas yog raws li Asmeskas cov roj av txheem. Cov kab yeeb nkab xa cov roj, chav, thiab dej rho tawm hauv av los ntawm cov kab yeeb kab mus rau cov roj thiab cov nkev tsim ua lag luam. Cov kab kav dej muaj xws li txuas hlua kav hlau thiab welded steel kav. Cov yeeb nkab tas muaj qhov kawg tiaj, xov xaus thiab xaws qhov xaus; cov hau kev txuas yog qhov kawg vuam, txuas txuas, txuas qhov txuas, thiab lwm yam.
Nrog rau kev txhim kho ntawm cov raj xaib steel phaj thev naus laus zis thiab kev nce qib ntawm welded yeeb nkab tsim thiab vuam tshuab, daim ntawv thov qhov chaw ntawm lub raj xa khoom welded yog maj mam nthuav dav, tshwj xeeb tshaj yog qhov zoo ntawm welded yeeb nyob rau hauv qhov ntau ntawm txoj kab uas loj-pab pawg spacing yog pom tseeb dua. Ntxiv rau tus nqi raug, welded yeeb nkab tau Cov kab yeeb nkab teb coj txoj hauj lwm ua, uas txwv qhov kev txhim kho ntawm stainless hlau seamless kab yeeb nkab. Hauv xyoo 2004, cov khoom tsim tawm ntawm cov kav hlau txuas txoj hlua tau yog li ntawm 400,000 tons, nrog rau qib steel nrog rau X42-70, thiab ntau yam ntawm cov kav dej sib txuas thiab cov kab hauv av.
Kev tsim cov khoom qib high-qib steel-qib kab coj los siv microalloying kev kho cua sov tshuab. Kev tsim cov nqi ntawm stainless hlau seamless kav yog qhov siab tshaj li ntawm cov welded kav. Nrog kev txhim kho ntawm cov qib steel, xws li X80 thiab siab dua steel-qib kab kav, tsis muaj kev txwv rau cov pa roj carbon sib npaug. Cov txheej txheem sib xyaw ntawm cov kav hlau txuas yog qhov nyuaj kom tau raws li cov neeg siv khoom xav tau; tag nrho 12Cr1moV alloy cov yeeb nkab cov yeeb yaj kiab tau ua tiav kev tshawb fawb los txhim kho kev txhim kho corrosion ntawm lawv cov kab kav dej thiab kev ua haujlwm ruaj khov nyob rau hauv huab cua sov thiab siab kub.
Pipeline steel khoom: L245, L360, A53, J55, N80, X42, X46, X52, X56, X60, X65, X70
Qhov tshwj xeeb ntawm kev muab cov yeeb nkab steel yeeb: +60-630 × 1.53-40
