DN1200 API 5L X70 PSL2 LSAW steel kav yog tsim los rau cov kav dej hauv lub cev, muab lub zog siab, kev ua haujlwm tawg, thiab kev ua haujlwm ruaj khov nyob rau hauv kev ua haujlwm siab txuas ntxiv - kev sib kis.
Cov yam ntxwv ntawm cov khoom siv thiab ntev -Kev kis tau tus mob nyob deb
API 5L X70 PSL2 yog lub siab - lub zog kav hlau nrog qhov tsawg kawg nkaus lub zog ntawm kwv yees li 485 MPa thiab lub zog tensile feem ntau yog li ntawm 570 txog 760 MPa. Cov tshuaj muaj pes tsawg leeg yog tswj nruj me ntsis, feem ntau txwv cov ntsiab lus carbon rau ib ncig ntawm 0.20 feem pua thaum tswj cov qib manganese ntawm 1.60 thiab 1.80 feem pua. Microalloying cov ntsiab lus xws li niobium, vanadium, thiab titanium yog ntxiv los ua kom zoo dua cov qauv nplej thiab txhim kho lub zog thiab qis -kub toughness. PSL2 cov kev cai kuj tseem txwv nruj dua rau cov sulfur thiab phosphorus, nrog rau qhov yuav tsum tau kuaj qhov cuam tshuam thiab tag nrho -ntev tsis- kev tshuaj xyuas kev puas tsuaj, ua kom muaj kev tiv thaiv siab rau kev tawg tawm hauv qhov ntev - cov kav dej.
Huayang Steel Yeeb Nkab tsim DN1200 LSAW kav siv cov thermomechanically tswj dov steel daim hlau, ua kom lub cev tsis sib xws thiab kev ua haujlwm ruaj khov. JCOE txoj kev tsim cov txheej txheem muab kev tswj xyuas qhov tseeb thiab cov phab ntsa tuab zoo sib xws. Longitudinal seams yog welded siv multi-pass submerged arc vuam, xa cov nkag mus tob thiab txhim khu kev qha weld kev ncaj ncees. Txhua cov yeeb nkab tau kuaj xyuas ultrasonic, kuaj radiographic, thiab ntsuas hydrostatic siab. Rau cov roj thiab roj kis tau tus mob, 3PE txheej sab nraud thiab cov txheej txheem ntws sab hauv feem ntau yog siv los txhim kho corrosion thiab txhim khu kev sib kis.
