Seamless steel kav muaj ntau ntawm kev siv.
1. General-hom phiaj seamless steel kav hlau yog dov los ntawm cov hlau loj lossis cov khoom siv loj tshaj plaws, thiab muaj cov txheej txheem rau cov kua dej.
2. Lawv tau muab rau peb pawg raws li kev siv sib txawv:
a. Muab raws li cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv neeg siv neeg;
b. Muab raws li cov khoom siv mechanical;
c. Muab raws li cov dej ntsuam xyuas. Cov kav hlau steel xa khoom hauv pawg A thiab B, yog tias siv los ua kom haum kua rau dej.
3. Special-purpose seamless pipes include seamless pipes for boilers, chemical power, geological seamless steel pipes, and seamless pipes for petroleum.
Seamless steel kav muaj hollow cross-seem thiab tau siv dav siv raws li cov raj xa dej, xws li cov roj av rau cov roj, roj av, dej thiab qee cov ntaub ntawv cov khoom siv. Piv nrog cov hlau tawv xws li cov hlau hloov pauv, cov kav hlau sib txuas yog qhov sib zog ntawm qhov hnyav thiab torsionional ua tau zoo ib yam, thiab yog tus neeg siv hluav taws xob sib txawv.
Nws yog dav siv nyob rau hauv kev tsim cov txheej txheem txheej txheem thiab tshuab hluav taws xob, xws li cov roj tho xaum, tsheb kauj vab, thiab cov hlau scaffolding siv hauv kev tsim kho. Kev siv cov kav hlau hlau tuaj tsim cov txheej txheem siv khoom siv, ua kom cov ntaub ntawv tsim khoom, txuag lub sijhawm ua haujlwm, thiab tau siv dav hauv cov yeeb nkab steel.
