Cov kav dej tuaj yeem raug cais los ntawm qhov xwm txheej ntawm kev thauj mus los rau hauv: Cov kav dej thiab cov kav dej, cov kav dej compressed, cov kav dej hauv cov kav dej, cov kav dej hydrogen, cov kav dej oxygen, cov kav dej acetylene, cov kav dej roj, cov kav dej roj, cov kav dej muaj kuab lom, cov kav dej muaj kuab lom, kua qaub - cov kav dej alkali, cov kav dej refrigerant, thiab lwm yam.
Hauv cov ntsiab lus
Rau tag nrho cov kav dej tau hais los saum toj no-txawm yog cov kav dej siab, siab - cov kav dej kub, lossis corrosion- cov kav dej tsis muaj zog- muaj ib yam khoom uas tuaj yeem ua tau raws li qhov yuav tsum tau ua: titanium thiab titanium alloy kav. Cov kav dej no muaj kev tiv thaiv corrosion tshwj xeeb, ua rau lawv zoo tagnrho rau ib puag ncig uas xav tau ntev -lub sij hawm tiv thaiv cov kua dej corrosive, xws li cov kav dej thiab cov kav dej, cov kua qaub- cov kav dej alkali, thiab cov kav dej demineralized. Rau siab - cov kav dej siab zoo li cov kav dej compressed, cov kav dej, thiab cov kav dej uas xav tau siab txaus- cov kabmob muaj peev xwm, cov kav dej titanium sawv tawm nrog lawv cov qauv tsim muaj zog thiab muaj peev xwm tswj tau lub zog ntawm qhov kub siab tshaj 400 degree, ua tau raws li qhov yuav tsum tau ua.
