Cov pa roj carbon steel kav yuav tsum tau cam khwb cia los ntawm cov hlau los yog cov khoom puag ncig steel los ntawm kev drilling, thiab ces kub dov, txias dov los yog txias kos. Carbon steel yeeb nkab plays lub luag haujlwm tseem ceeb hauv Tuam Tshoj txoj kev lag luam seamless steel yeeb nkab. Cov ntaub ntawv tseem ceeb yog Q235, 20#, 35#, 45#, 16Mn. Cov khoom siv tseem ceeb tshaj plaws suav nrog cov qauv hauv tebchaws, Asmeskas cov qauv, cov qauv Japanese, thiab lwm yam. Ntawm lawv, cov qauv hauv tebchaws suav nrog Ministry of Chemical Industry cov qauv, Sinopec yeeb nkab haum qauv, thiab cov qauv hluav taws xob engineering yeeb nkab haum. Cia peb saib cov txiaj ntsig ntawm carbon steel kav.
Kev siv cov pa roj carbon steel kav:
1. Cov kav dej rau kev siv tshuab engineering. Xws li cov qauv hauv dav hlau, tsheb ib nrab qag raj, cov raj xa hluav taws xob, cov tsheb laij teb loj cov qauv rau cov tsheb, tsheb laij teb cov raj dej txias, cov raj square raj, thiab cov raj duab plaub rau kev ua liaj ua teb locomotives, transformer tubes, thiab bearing tubes thiab lwm yam. 2.
Cov yeeb nkab drilling rau roj geological ib puag ncig. Xws li: roj drilling kav, roj drilling kav (kelly thiab hex laum kav), drilling jacks, roj pipelines, roj-impermeable casings thiab ntau yam T-joints, geological ib puag ncig drilling kav (tub ntxhais tubing, waterproof casings, nyob drill rods, xyaum) jacks, rings thiab dowel connectors, thiab lwm yam).
3. Cov kav dej tshuaj. Xws li: roj av tawg cov kav dej, cov kav dej rau cov khoom siv hluav taws xob, thiab cov kav dej rau cov khoom siv tshuaj thiab cov khoom siv, cov kav dej tsis muaj zog acid-resistant, cov kav dej cua txias rau cov organic chiv, thiab cov kav dej rau cov khoom siv tshuaj cog qoob loo, thiab lwm yam. 4.
Cov kav dej rau cov kav dej. Xws li: dej, roj pipelines, seamless kav rau compressed cua pipelines, roj pipelines, pipelines rau roj thiab roj lub ntsiab kab. Cov kav dej loj rau kev ua liaj ua teb dej thiab cov kav dej rau cov khoom siv dej sprinkler, thiab lwm yam. 5.
Piping rau cov khoom siv thermal. Xws li cov kav dej kub npau npau thiab cov kav dej saturated steam siv nyob rau hauv cov cua kub cua sov, cov kav dej superheat, cov kav dej pa taws loj, cov kav dej me me, cov kav dej arc cib, thiab cov kav dej kub kub uas siv rau hauv cov cua sov ntawm cov hluav taws xob locomotives.
6. Tswj los ntawm lwm lub tuam tsev. Xws li: cov raj rau cov tais diav (tub rau cov roj liquefied gas cylinders thiab cov khoom siv dav dav), cov raj rau cov cuab yeej thiab cov ntsuas, cov raj rau cov neeg saib xyuas, koob txhaj tshuaj, thiab cov raj rau kev kho mob, thiab lwm yam.
