Cov pa roj carbon steel yog ua los ntawm cov hlau castings los yog cov khoom sib hloov steel los ntawm qhov los ua cov hlab ntsha, thiab tom qab ntawd ua los ntawm kub dov, txias dov lossis txias txias. Carbon steel tubes muaj txoj haujlwm tseem ceeb hauv Tuam Tshoj txoj kev lag luam seamless steel raj. Cov ntaub ntawv tseem ceeb yog q235, 20#, 35#, 45#, thiab 16mn. Cov qauv tsim khoom tseem ceeb tshaj plaws suav nrog cov qauv hauv tebchaws, Asmeskas cov qauv, cov qauv Japanese, thiab lwm yam, ntawm cov qauv hauv tebchaws suav nrog Ministry of Chemical Industry standard, Sinopec yeeb nkab haum qauv, thiab cov qauv hluav taws xob engineering yeeb nkab haum. Cia peb saib cov txiaj ntsig ntawm carbon steel tubes.

Kev siv carbon steel tube:

1. Cov kav dej rau cov kav dej. Xws li: seamless raj rau dej, kav dej, kav dej, kav dej, roj kav dej, thiab cov kav dej rau cov roj thiab cov khoom siv roj ntsha. Agricultural irrigation faucets nrog cov kav dej thiab cov kav dej sprinkler, thiab lwm yam.
2. Cov raj rau cov khoom siv thermal. Xws li cov kav dej kub npau npau, cov kav dej superheated rau cov boilers dav dav, cov kav dej superheating, cov kav dej pa taws loj, cov kav dej me me, cov kav dej cib thiab cov kav dej kub thiab kub siab boiler kav rau locomotive boilers.
3. Cov kav dej rau kev lag luam machinery. Xws li cov kav dej aviation (cov kav dej, cov kav dej elliptical, cov kav dej tiaj tus), cov kav dej ib nrab ntawm lub tsheb, cov kav dej qag, cov tsheb laij teb cov kav dej, tsheb laij teb cov kav dej txias, cov kav dej ua liaj ua teb square kav thiab cov kav dej, cov kav dej transformer thiab bearings raj thiab lwm yam. .
4. Cov kav dej rau roj av geological drilling. Xws li: roj laum yeeb nkab, roj laum yeeb nkab (kelly thiab hexagonal laum yeeb nkab), laum yeeb nkab, roj tubing, roj casing thiab ntau yam yeeb nkab sib txuas, geological drilling yeeb nkab (tub ntxhais yeeb nkab, casing, active laum yeeb nkab, laum yeeb nkab), xovxwm hoop thiab pin pob qij txha, thiab lwm yam).
5. Cov kav dej rau kev lag luam tshuaj. Xws li: cov roj tawg cov kav dej, cov khoom siv tshuaj tua hluav taws kub thiab cov kav dej, cov kav dej tsis muaj zog acid, cov kav dej siab rau cov chiv, thiab cov kav dej rau kev thauj cov tshuaj lom neeg, thiab lwm yam.
6. Lwm lub tuam tsev siv cov kav dej. Xws li: cov raj rau cov thawv ntim (cov raj rau lub tog raj kheej siab thiab cov raj rau cov thawv ntim dav dav), cov raj siv rau kev ntsuas, cov raj rau cov neeg saib xyuas, koob txhaj tshuaj thiab cov raj rau cov khoom siv kho mob, thiab lwm yam.

Raws li cov khoom siv steel yeeb nkab:

Cov kav hlau hlau tuaj yeem muab faib ua cov kav dej carbon, cov kav hlau alloy, cov kav hlau tsis muaj steel, thiab lwm yam raws li cov khoom siv yeeb nkab (xws li hom hlau). Cov pa roj carbon monoxide tuaj yeem muab faib ua cov pa roj carbon zoo tib yam cov kav dej thiab cov kav dej zoo carbon zoo. Alloy tubes tuaj yeem muab faib ntxiv rau: cov hlau tsis tshua muaj hlau, cov raj hlau alloy, cov hlau alloy siab, thiab cov raj muaj zog. Cov kabmob, cov raj kub- thiab acid-resistant stainless hlau, precision alloy (xws li Kovar) raj, thiab superalloy raj, thiab lwm yam.
