Daim ntawv thov
1.Manufacturing tseem ceeb siab- bearing khoom xws li cov hlab ntsha siab, muaj boilers thiab tshav kub exchangers, uas yog dav deployed nyob rau hauv cov roj thiab roj extraction, petrochemical ua thiab thermal zog tsim industries; Cov khoom siv no yuav tsum tau ua haujlwm ntev - lub sijhawm ua haujlwm nyob rau hauv qhov kub thiab txias - siab, thiab cov khoom siv kho tshuab ruaj khov ua kom cov cuab yeej muaj kev nyab xeeb thiab kev ntseeg tau.
2.Ua siab - kub thiab siab - cov kav dej siab rau kev thauj cov xov xwm corrosive lossis siab - cov kua dej kub; Cov kav dej no tsim nyog rau kev ua haujlwm hnyav xws li refinery reactor qhov hluav taws xob, cov kav dej xa hluav taws xob thiab cov kab xa dej tshuaj lom neeg, ua kom zoo rau qhov kub thiab txias.
3.Fabricating core Cheebtsam rau qaub roj ib puag ncig (xws li, natural gas extraction wells, gass collecting stations and sour oil processing units); leveraging nws zoo heev tsis kam mus rau hydrogen embrittlement thiab sulfide kev nyuaj siab corrosion cracking (SSCC), cov khoom yuav tiv taus qhov yaig ntawm hydrogen sulfide thiab lwm yam corrosive gases, ncua kev pab cuam lub neej ntawm cov khoom nyob rau hauv xws li ib puag ncig hnyav.
Qhov zoo
Kev ua haujlwm siab -kub: quenched thiab tempered kev kho cua sov kom ruaj khov tensile lub zog (515-690 MPa) thiab yield zog (tsawg kawg 310 MPa) nyob rau hauv ntev -lub sij hawm nce- kub thiab siab - siab loads.
Muaj zog corrosion kuj: Optimized Cr-Mo alloy muaj pes tsawg leeg muab kev tiv thaiv zoo rau hydrogen embrittlement thiab sulfide corrosion, haum rau corrosive media scenarios.
Kev ua tau zoo: Muaj qhov zoo tshaj plaws weldability thiab formability, yooj yim rau fabrication complex - zoo li cov cuab yeej thiab txo cov khoom nyuaj.
Yooj yim specifications: Pa thickness ranges ntawm 5 hli mus rau 150 hli, nrog customizable dav thiab ntev kom tau raws li ntau yam engineering xav tau.
International txuj compatibility: Muaj cov ntaub ntawv sib npaug hauv European, Nyiv, thiab German cov qauv (xws li EN 10028-2 10CrMo5-}5), ua kom cov khoom hloov pauv hloov pauv hauv cov haujlwm hla ciam teb.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
Cov khoom siv dab tsi yog qib 5 steel?
Qib 5. Ua los ntawm cov pa roj carbon nruab nrab thiab tawv tawv kom muaj zog dua thiab ua haujlwm ntev, qib 5 bolt yog qhov txawv ntawm 3 kab radial thiab cog lus tensile zog ntawm 105,000 thiab 120,000 psi. Lawv feem ntau pom muaj nyob rau hauv daim ntawv thov tsheb lossis cov uas xav tau lub zog nruab nrab.
ASTM A387 sib npaug li cas?
Ntawm cov ASTM A387 Qib 22 sib npaug steel qib, SA387 Qib 22, 10CrMo9-10 yog nrov dua li lwm yam sib npaug. SA387 Qib 22 steel yog raws li ASME SA387 / SA387M tus qauv. Kev ua haujlwm tshuaj lom neeg thiab kev ua haujlwm ntawm SA387 Qib 22 steel yuav luag zoo ib yam nrog ASTM A387 Qib 22 steel.
