SSAW steel kavyog ua los ntawm sawb steel coils li raw cov ntaub ntawv, extruded ntawm qhov kub thiab txias, thiab welded los ntawm kev siv ob-xaim ob-sided submerged arc vuam txheej txheem.Lub tshuab tsim tshiab no ua kom cov qib siab tshaj plaws ntawm kev ua tau zoo thiab ua haujlwm ntev, ua rau peb cov kav dej zoo tagnrho rau kev siv kab hauv av.
Lub plawv ntawm nokauv steel yeeb nkabyog nws qhov tshwj xeeb kauv tsim.Cov sawb hlau yog pub rau hauv cov khoom siv welded yeeb nkab thiab maj mam dov los ntawm ntau cov chais los tsim ib lub voj voos kheej kheej nrog qhov qhib qhov sib txawv.Nws muaj peev xwm los kho qhov txo qis ntawm cov menyuam extrusion, thiab qhov sib txawv ntawm qhov sib txuas tuaj yeem tswj tau ntawm 1-3mm kom ntseeg tau tias muaj kev sib txuas thiab ruaj khov.Tsis tas li ntawd, ob qhov kawg ntawm cov welded sib koom ua ke zoo kawg nkaus flush, muab kev ua tiav zoo.
SSAW steel kav muaj ntau yam ntxwv uas sib txawv ntawm cov kav hlau ib txwm muaj.Nws cov qauv kauv muaj lub zog zoo heev thiab ua haujlwm rau sab nraud quab yuam, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm kev xa dej.Tsis tas li ntawd, cov txheej txheem vuam zoo ua kom ntseeg tau tias cov pob qij txha yog cov ntaub ntawv pov thawj thiab tiv thaiv dej seepage los yog paug.Nrog nws cov kev tsim kho ruaj khov thiab kev sib txuas ruaj ntseg, cov yeeb nkab no ua kom muaj kev ua haujlwm ntev thiab txo qhov kev xav tau ntawm kev saib xyuas, ua rau nws muaj txiaj ntsig zoo rau txhua txoj haujlwm hauv av.
