ERW steel yeeb nkab yog tsim los ntawm kub dov coil ua nyob rau hauv steel zeb. Tag nrho cov coils tuaj yeem raug txheeb xyuas raws li daim ntawv pov thawj tau txais los ntawm steel zeb rau lawv cov chemistry thiab mechanical zog.Qhov txheej txheem ntawm ERW yeeb nkab pib nrog ib txoj kab dav dav. Qhov dav ntawm strip yog roughly sib npaug rau ib puag ncig ntawm cov yeeb nkab yuav tsum tau ua. Cov npoo ntawm cov kauj yog sheared rau pre-specified widths nyob rau hauv slitting kab.Cov txheej txheem yuav uncoiling & leveling ntawm coils thiab ua tib yam. Cov hlau lead kawg ntawm txhua lub kauj yog squared los ntawm kev ua haujlwm shearing rau threading rau hauv lub zeb. Tom qab ntawd qhov kawg no tau koom nrog coil kawg ntawm cov txheej txheem tawm mus kom muaj kev txuas ntxiv hauv kev tsim khoom thiab txo qhov poob.
BRISK STEEL yog cov cuab yeej zoo thiab cov kws tshaj lij kev cob qhia thiab thev naus laus zis. HFW 426 weld yeeb nkab zeb tau qhia hnub no lub ntiaj teb-chav roj av steel kav tsim cov thev naus laus zis thiab khoom siv, suav nrog kev tsim
tshuab thiab milling pom los ntawm Janpanese KUSAKABE Tuam Txhab, cov khoom siv lub xeev siab zaus welder los ntawm Norwegian EFD Company, servo lub cev muaj zog los ntawm German SIEMENS Company, thiab lwm yam khoom siv yog tsim los ntawm cov chaw ua liaj ua teb hauv tsev.Cov khoom muaj xws li: roj castings ntsib United States API 5CT Standard for thesteel grae of H40, J55, K55, N80 thiab L80 raws li zoo raws li cov roj thiab cov nkev pipelines txaus siab rau lub tebchaws United States API 5L Standard rau steel qib X80 thiab hauv qab no thiab cov ASTM A53 Standard, German DIN 17100 Standard, GB /T9711{11}}.
