a. Thaum lub sijhawm tus txheej txheem tsim, cov phaj steel deforms tusyees, qhov kev nyuaj siab tsis loj, thiab saum npoo tsis tsim khawb. Kev ua tiav kauv hlau yeeb nkab muaj ntau dua qhov hloov tau yooj yim hauv qhov loj me thiab kev txwv ntawm ntau ntawm lub taub thiab phab ntsa tuab. Tshwj xeeb, cov qib high-qib steel-qib tuab-walled kav, tshwj xeeb tshaj yog cov kav hlau me thiab nruab nrab-tuab-phab ntsa, muaj qhov zoo uas lwm cov txheej txheem tsis tuaj yeem sib phim, uas tuaj yeem txaus siab rau cov neeg siv. Muaj ntau qhov yuav tsum tau nyob rau hauv cov nqe lus ntawm muab kauv steel yeeb yam tshwj xeeb.
b. Adopting advanced ob-sided submerged arc vuam tshuab, vuam tuaj yeem pom tseeb hauv txoj haujlwm zoo, thiab nws tsis yooj yim kom muaj qhov tsis xws luag xws li lub ntug tsis raug, vuam sib txawv thiab tsis tiav, thiab nws yooj yim los tswj lub vuam zoo.
c. Ua tau 100% kev soj ntsuam zoo ntawm cov kav hlau, kom txhua tus txheej txheem ntawm cov kav hlau yog nyob hauv kev soj ntsuam thiab tshuaj xyuas, uas tau lees tias cov khoom zoo.
d. Txhua yam cuab yeej siv ntawm tag nrho cov kab muaj cov kev ua haujlwm sib txuas nrog cov khoos phis tawm cov ntaub ntawv kom paub cov ntaub ntawv xa hluav taws xob tam sim ntawd, thiab chav tswj hauv nruab nrab yuav kuaj xyuas cov cuab yeej kev ntawm cov txheej txheem.
