Cov yeeb nkab hlau muaj peev xwm muab faib ua ob pawg raws li txoj kev tsim khoom: cov yeeb nkab hlau tsis sib xws thiab cov yeeb nkab hlau sib txuas, cov yeeb nkab hlau sib txuas yog hu ua cov yeeb nkab hlau ncaj.

1. Cov yeeb nkab hlau tsis muaj seamless muaj peev xwm muab faib ua: cov yeeb nkab kub dov seamless, cov yeeb nkab txias rub, cov yeeb nkab precision, cov yeeb nkab kub nthuav dav, cov yeeb nkab txias spinning thiab cov yeeb nkab extrusion, thiab lwm yam. Cov yeeb nkab hlau tsis muaj seamless yog ua los ntawm cov hlau carbon zoo lossis cov hlau alloy, uas tuaj yeem dov kub lossis dov txias (kos).

2. Cov yeeb nkab hlau vuam tau muab faib ua cov yeeb nkab vuam cua sov, cov yeeb nkab vuam hluav taws xob (vuam tsis kam) thiab cov yeeb nkab vuam arc tsis siv neeg vim nws cov qauv vuam sib txawv, muab faib ua cov yeeb nkab vuam ncaj thiab cov yeeb nkab vuam kauv ob hom, vim nws qhov kawg zoo li cas, muab faib ua cov yeeb nkab vuam voj voog thiab cov yeeb nkab vuam zoo li tshwj xeeb (square, flat, thiab lwm yam). Cov yeeb nkab hlau raws li cov khoom siv raj (piv txwv li hlau) tuaj yeem muab faib ua: cov yeeb nkab carbon thiab cov yeeb nkab alloy, cov yeeb nkab stainless hlau, thiab lwm yam. Cov yeeb nkab carbon tuaj yeem muab faib ua cov yeeb nkab carbon steel thiab cov yeeb nkab carbon zoo. Cov yeeb nkab alloy tuaj yeem muab faib ua:cov yeeb nkab tsis tshua muaj hlau, cov yeeb nkab hlau,cov yeeb nkab hlau siab, cov yeeb nkab muaj zog heev. Cov raj xa dej, cov raj xa dej kub thiab cov raj xa dej tsis xeb, cov hlau nplaum precision (xws li cov hlau txiav) thiab cov raj xa dej kub siab, thiab lwm yam.

Raws li cov yam ntxwv ntawm cov txheej txheem

Cov yeeb nkab hlau raws li cov yam ntxwv ntawm cov txheej txheem saum npoo tuaj yeem muab faib ua: cov yeeb nkab dub (tsis tau coated) thiab cov yeeb nkab coated.

Cov yeeb nkab txheej muaj cov yeeb nkab galvanized, cov yeeb nkab txhuas plating, cov yeeb nkab chrome plating, cov yeeb nkab aluminizing thiab lwm cov txheej hlau ntawm cov yeeb nkab hlau.

Cov raj txheej muaj cov raj txheej sab nraud, cov raj txheej sab hauv, cov raj txheej sab hauv thiab sab nraud. Cov txheej txheej feem ntau yog yas, epoxy resin, thee tar epoxy resin thiab ntau yam iav hom tiv thaiv xeb txheej.

Kev faib tawm los ntawm kev siv

Cov Kauj Ruam 1 Cov Yeeb Nkab rau cov kav dej. Xws li: dej, yeeb nkab roj, yeeb nkab pa nrog cov yeeb nkab tsis sib txuas,roj kis yeeb nkab, roj thiab roj av yeeb nkab. Kev ua liaj ua teb dej kais dej nrog yeeb nkab thiab cov yeeb nkab dej txau.

2. Cov kav dej rau cov khoom siv thermal. Xws li lub boiler dav dav nrog cov kav dej kub npau npau,cov yeeb nkab ua pa kub heev, cov yeeb nkab cua sov boiler locomotive, cov yeeb nkab pa luam yeeb, cov yeeb nkab pa luam yeeb me me, cov yeeb nkab cib thiab qhov kub thiab txias thiabraj boiler siab siab, thiab lwm yam.

3. Cov yeeb nkab kev lag luam kho tshuabXws li cov yeeb nkab qauv aviation (cov yeeb nkab puag ncig, cov yeeb nkab ellipse, cov yeeb nkab tiaj tus ellipse), cov yeeb nkab ib nrab ntawm lub tsheb, cov yeeb nkab qag, cov yeeb nkab qauv tsheb laij teb, cov yeeb nkab roj txias tsheb laij teb, cov yeeb nkab transformer thiab cov yeeb nkab bearing, thiab lwm yam.

4. Cov yeeb nkab roj av geology drilling. Xws li: cov yeeb nkab roj av drilling, cov yeeb nkab roj av, cov roj av casing thiab ntau yam yeeb nkab sib koom ua ke, cov yeeb nkab geological drilling (casing, cov yeeb nkab laum nquag, drilling, hoop thiab pin sib koom ua ke, thiab lwm yam).

5. Cov yeeb nkab kev lag luam tshuaj lom neeg. Xws li: roj av tawg yeeb nkab, cov khoom siv tshuaj lom neeg kub exchanger thiab yeeb nkab yeeb nkab, stainless acid-resistant yeeb nkab, chiv nrog siab siab yeeb nkab thiab thauj tshuaj lom neeg nruab nrab yeeb nkab, thiab lwm yam.

6. Lwm lub chaw haujlwm siv cov kav dej. Xws li: cov kav dej thawv (cov kav dej roj siab thiab cov kav dej thawv dav dav), cov kav dej ntsuas thiab lwm yam.
