Kev tsim cov khaub thuas kos duab roj av tawg raj tuaj yeem ua tau txias-kub, txias kos, txias-draw, txias-siv ntau lawm. Siv cov txheej txheem kos duab, cov cuab yeej siv yooj yim, kev nqis peev tsawg, kev ua haujlwm yooj yim thiab kev saib xyuas thiab lwm yam. Tab sis lub drawback yog theem nrab ntawm ntau, tus nqi ntoo. Siv cov txheej txheem txias txias yog qhov nyuaj dua, thiab kev nqis peev ntau dua, tab sis tuaj yeem txo cov txheej txheem nruab nrab, txhim kho cov txiaj ntsig, siab seamless steel khoom loj, thiab qhov tseeb ntawm qhov chaw, tshwj xeeb tshaj yog rau high-precision seamless thiab tsis tshua muaj siab-walled seamless raj.

Vim muaj kev txwv mill yob dhau los ntawm tus lej thiab tus nqi ntawm cov khoom tiav tiav tsis tuaj yeem ntau dhau; txias dov thiab txias sib koom txheej txheem tsim khoom los tsim cov khoom tiav, nrog cov khoom zoo hlau ua lub sij hawm luv luv, txo qhov nruab nrab degreasing, kho cua sov, faint, Jiao ncaj cov txheej txheem, txuag zog, txo cov hlau noj, tsawg raw khoom specifications thiab yog li ntawd. Petroleum cracking tube tuaj yeem yog txias rub cov kua qaub, hydrochloric acid, sib xyaw acid, hydrofluoric acid thiab lwm yam. Cov pa roj carbon steel thiab alloy seamless steel haum rau sulfuric acid, zoo carbon steel thiab alloy steel seamless precision tsim nyog rau hydrochloric acid.
