Cov pa roj carbon steel yeeb nkab tau zoo corrosion kuj, siab bearing muaj peev xwm thiab machinability, thiab yog dav siv nyob rau hauv ntau lub teb.
1. Cov kav dej rau kev siv tshuab engineering. Xws li cov qauv hauv dav hlau, tsheb ib nrab ncej raj, cov raj xa hluav taws xob, cov tsheb laij teb loj cov qauv rau cov tsheb, tsheb laij teb dej txias tubes, cov raj square raj thiab cov raj duab plaub rau kev ua liaj ua teb locomotives, transformer tubes thiab dov bearing raj, thiab lwm yam.
2. Drilling kav rau roj av geological ib puag ncig. Xws li: roj drilling kav, roj drilling kav (kelly thiab hexagonal laum kav), laum jacks, roj pipelines, roj waterproof casings thiab ntau yam tee pob qij txha, geological ib puag ncig drilling kav (tub ntxhais tubing, waterproof casings, nquag drilling rods, laum jacks, hoops thiab pin connectors, thiab lwm yam).
3. Cov kav dej tshuaj. Xws li: petroleum cracking pipes, pipelines for heat exchangers and pipelines of chemical machinery and equipment, stainless steel acid-resistant pipes, air-conditioning pipes for organic chiv and pipelines for transports chemical plant material, etc.
4. Cov raj rau cov kav dej. Xws li: dej, roj kav, seamless kav rau compressed cua kav, roj pipelines, kav rau roj thiab roj cov ntsiab lus. Ua cov kav dej rau kev ua liaj ua teb dej thiab cov kav dej rau cov khoom siv dej sprinkler, thiab lwm yam.
5. Cov kav dej rau cov khoom siv thermal. Xws li cov kav dej kub npau npau thiab cov kav dej saturated steam kav siv rau hauv cov cua kub cua sov, cov kav dej kub dhau, cov kav dej pa taws loj, cov kav dej me me, cov kav dej cib thiab cov kav dej kub kub tsis tu ncua siv rau hauv hluav taws xob locomotive cua sov furnaces.
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 twj thiab cov ntsuas, cov raj rau cov neeg saib xyuas, koob txhaj tshuaj thiab cov raj rau kev kho mob, thiab lwm yam.
Qhov sib txawv tseem ceeb ntawm cov kav hlau cam khwb cia thiab cov pa roj carbon steel yeeb nkab yog tias lawv muaj kev siv sib txawv, cov yam ntxwv sib txawv thiab kev faib tawm sib txawv.
1. Cam khwb cia hlau kav nrog kev siv sib txawv yog tsim rau cov kav dej hauv tsev, cov kav dej nag, cov kav dej khib nyiab thiab cov kav dej nag nyob rau sab hauv ntawm cov vaj tse thiab cov vaj tse uas tau tsim tshiab, nthuav dav, thiab rov tsim kho thiab txuas nrog clamps. Cov pa roj carbon steel yeeb nkab yog siv rau kev xa cov kua dej thiab cov hmoov av, sib pauv lub zog hluav taws xob, tsim cov khoom siv kho tshuab thiab ntim khoom, thiab yog hom kev lag luam ntawm cov hlau. Kev siv cov yeeb nkab steel los tsim qhov chaw trusses, txhua kab thiab cov cuab yeej txhawb nqa ntawm lub tsev tsim tuaj yeem txo qhov hnyav, txuag 20-40% ntawm cov hlau, thiab paub txog kev tsim kho tshuab.
2. Cov yam ntxwv sib txawv, cam khwb cia hlau yeeb nkab muaj qhov zoo ntawm kev ua haujlwm zoo thiab txhim khu kev qha, tsis tshua muaj kev puas tsuaj, kev tsim kho yooj yim thiab kev saib xyuas, thiab kev ua haujlwm zoo los tiv thaiv corrosion.
Tsis tas li ntawd, carbon steel yeeb nkab yog steel yeeb nkab welded los ntawm coils. Nws txoj kev ua haujlwm yog qhov yooj yim, tab sis nws lub neej ntev yog li ntawm 20-30 xyoo, thiab tus nqi yog piv rau cov kav dej cam khwb cia hlau. Cam khwb cia hlau kav yog cam khwb cia hlau kav los ntawm high-ceev centrifuges. Lawv tiv taus corrosion thiab siab rau ntau tshaj 70 xyoo. Lawv feem ntau yog siv los ua cov dej hauv av thiab cov kav dej hauv nroog.
