GNEE Steel yog ib qho ntawm cov chaw tsim khoom, xa tawm, thiab cov chaw muag khoom ntawm Super Duplex Steel UNS S32750 Welded Pipe. Peb muab thiab tsim peb cov khoom raws li peb cov neeg siv khoom xav tau. Peb ua raws li cov kev qhia tshwj xeeb thiab cov qauv sib txawv los tsim cov khoom. Lub alloy super duplex steel uns s32750 yog sib xyaw ntawm high chromium, npib tsib xee, thiab molybdenum uas tsis tshua muaj tooj liab, silicon, carbon, hlau. Vim yog cov chromium siab thiab npib tsib xee alloy, cov kav dej welded muab cov cuab yeej tiv thaiv corrosion siab. Lub alloy super duplex steel welded yeeb nkab tau zoo heev corrosion kuj, pitting thiab crevice corrosion nyob rau hauv seawater thiab chloride uas muaj cua. Cov kav dej welded muaj lub zog txhua yam, tensile, zoo ductility.
Super Duplex Steel 1.4410 Welded Pipes yog siv nyob rau hauv cov xov tooj ntawm kev lag luam xws li dej desalinization, roj thiab roj, ntawv thiab pulp, tshav kub exchanger, condenser, petrochemical, thiab ntau lwm lub tuam txhab thiab. Nws muaj kev ua haujlwm zoo thiab weldability. Txawm li cas los xij, cov yeeb nkab muaj ntau daim ntawv thov vim muaj qhov zoo ductility, tiv thaiv chloride kev nyuaj siab thiab tawg kev ntxhov siab. Cov yeeb nkab tsis muaj xeb thiab nws yooj yim ua haujlwm hauv ib puag ncig acid. Ua ntej xa peb cov khoom peb ua ntau yam kev ntsuam xyuas xws li micro thiab macro test, intergranular test, kev puas tsuaj, kev ntsuam xyuas txhua yam thiab tshuaj, thiab ntau lwm yam kev ntsuam xyuas.
