Kev Tsim Kho thiab Kev Ncaj Ncees Zoo
Txheej txheem vuam: kav dej feem ntau welded siv lub siab - zaus induction induction cov khoom siv.
Tshaj tawm - Weld Kev Kho Mob: Tom qab vuam, cov kav dej dhau los ua haujlwm txias thiab ua kom muaj kev ntxhov siab thaum ua tiav cov khoom xav tau.
Kev kho deg: kev kho deg yog tsim los tshem tawm cov impurities thiab txhim kho corrosion corrosion. Pickling los yog ci annaling yog siv los xyuas kom meej qhov chaw zaum kawg yog huv thiab dawb ntawm nplai.
Kev Kuaj: Qhov kawg cov khoom lag luam hauv kev kuaj ntau, suav nrog kev sim tshuab, kom ntseeg tau tias nws tau tsim nyog rau nws cov kev xav siv.
Gnee steel tshwj xeeb hauv kev tsim cov khoom ntau ntawm cov khoom lag luam stainless hlau. Gnee Steel cov khoom ntim khoom muaj xws li: cov hlua hlau: cov kav hlau: cov kav hlau nrog cov kab yeeb yaj kiab txheej lossis tsawg dua yog cov xeb thaum hiav txwv thaum hiav txwv thaum hiav txwv, thiab tom qab ntawd ruaj ntseg nrog hlau strapping. Cov kab mob ntoo / crates: pipes feem ntau ntim rau hauv cov tsiaj ntoo lossis crates los tiv thaiv cov kav dej thaum thauj mus los, tshwj xeeb yog cov uas nyob ntev dua lossis cov kab hniav loj dua. Seaworthy export ntim: Cov chaw muag khoom siv cov txheej txheem seaworthy export export cov ntaub ntawv sau thiab cov tswv yim los tiv thaiv cov kav dej thaum lub sijhawm thauj mus los. Tarpaulin Ntim: Qhov no tiv thaiv los nag, seawater, thiab lwm yam sab nraud los ntawm kev nkag mus rau lub crates export thaum thauj mus los. GNEE steel tshwj xeeb hauv kev tsim khoom thiab muag khoom ntawm alloy cov ntaub ntawv.
