SSAWW STEEK PIPESyog ua los ntawm sawb hlau coils li cov ntaub ntawv raw, extruded ntawm tas mus li kub, thiab welded los ntawm tsis siv neeg hlau ob npaug rau arc vuam txheej txheem. Qhov kev siv tshuab ntau dua tshiab ua kom cov qib siab tshaj plaws ntawm qhov siab tshaj plaws thiab kav ntev, ua kom peb cov pipes zoo tagnrho rau cov dej hauv av.
Lub plawv ntawm noMuab Kauv Steel Yeeb Nkabyog nws qhov tshwj xeeb kauv tsim. Cov hlau strip yog pub rau hauv welded yeeb nkab ntaus ntawv thiab maj mam dov los ntawm ntau chais los ua ib lub voj voos kom muaj qhov qhib. Nws muaj peev xwm kho qhov txo cov nyiaj txo qis, thiab weld sib txawv tuaj yeem tswj hwm ntawm 1-3mm los xyuas kom meej ib qho kev sib txuas thiab cov chaw sib txuas. Tsis tas li ntawd, ob qho kawg ntawm kev sib koom ua ke welded tau txig yaug, muab kev ua tiav zoo tag nrho.
SSAWW steel kav muaj ntau tus yam ntxwv uas sib txawv lawv los ntawm cov kav hlau tsoos hlau. Nws tus kauv qauv muaj lub zog zoo thiab tawm tsam rau sab nraud rog, kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov khoom xa dej. Tsis tas li ntawd, cov txheej txheem vuam zoo ua kom ntseeg tau tias cov pob qij txha yog cov tshuaj sib xyaw ua pov thawj thiab tiv thaiv kom tsis txhob muaj dej. Nrog nws cov kev tsim kho ruaj khov thiab ruaj ntseg sib txuas, cov yeeb nkab no ua kom muaj kev ua tau zoo ntev thiab ua kom tau txais txiaj ntsig zoo ntawm txoj haujlwm hauv av.
