ASTM A691 Qib 1-1/4 CR Alloy Steel Yeeb Nkab
gnee cev team
ASTM A691 Qib 1-1/4 CR ncaj seam welded yeeb nkab yog cov khoom siv hlau siv dav hauv qhov kub thiab txias, kub siab thiab corrosive ib puag ncig. Nws yog tsim los ntawm cov hlau tsis tshua muaj carbon hlau thiab ua tiav los ntawm cov txheej txheem ncaj seam vuam, uas muaj kev tiv thaiv corrosion zoo heev thiab muaj zog txhua yam. Cov khoom siv hauv cov kav dej no yog siv dav hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob, hluav taws xob nuclear thiab lwm yam kev lag luam los thauj cov kub kub, siab kub, nplaim taws, tawg lossis corrosive media.
SA691 steel yeeb nkab yog tus qauv rau electrofusion welded steel thiab alloy steel rau kev kub siab thiab kev kub siab rov xav txog tej yam kev mob. Qib ntawm cov yeeb nkab steel ncav cuag SA691Gr1-1/4Cr thiab yuav tsum tau txais kev kho kev ntxhov siab, kuaj hluav taws xob thiab ntsuas hydraulic. SA691Cr1-1/4CrCL22 yog ib hom CR-MO cov cua sov-resistant steel nrog cov ntsiab lus ntawm 2.25% CR thiab 1% MO. Sib npaug rau seamless yeeb nkab SA-335P22.
ASTM A691 yog American Society for Testing and Materials standard for electrofusion welded carbon and alloy steel pipes for high temperature and high pressure service conditions. 1 1/4Cr yog qib steel yeeb nkab, tshwj xeeb tshaj yog 1 1/4% chromium, 1/2% molybdenum steel qib. 22 yog lub xeev kev kho cua sov.
