Roj yeeb
Ib tug ntev sawb ntawm cov hlau nrog ib tug hollow seem thiab tsis muaj pob qij txha nyob ib ncig ntawm lub perimeter.
Nws yog dav siv hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li oil laum cov kav dej, tsheb tsav shafts, tsheb kauj vab ncej, thiabsteel scaffoldingsiv hauv kev tsim kho cov duab txawb, thiab lwm yam. Siv cov roj av tawg cov kav dej los tsim cov nplhaib tuaj yeem txhim kho kev siv cov khoom siv, ua kom yooj yim tsim cov txheej txheem, txuag cov ntaub ntawv thiab ua cov txiv neej-teev, xws li dov bearing rings, jack sets, thiab lwm yam., tau dav siv. hauv cov kav hlau.Roj tawg rajkuj yog ib qho khoom siv tsis tau rau ntau yam riam phom, thiab cov thoob, cov thoob, thiab lwm yam yuav tsum tau ua los ntawm cov roj tawg raj. Petroleum cracking pipes tuaj yeem muab faib ua cov kav dej sib txuas thiab cov kav dej tshwj xeeb raws li cov duab ntawm thaj chaw hla. Vim tias qhov xwm txheej ntawm qhov sib npaug sib npaug, cov roj tawg lub raj muaj qhov loj tshaj plaws, thiab cov kua dej ntau tuaj yeem thauj tau nrog cov hlab ntsha.
