S275JR Longitudinal Submerged -Arc Welded Steel Pipe

S275JR LSAW Ncaj Seam Welded Pipe Taw Qhia

S275JR longitudinal submerged arc welded steel yeeb nkab yog cov khoom siv yeeb nkab ua los ntawm European tus qauv qauv steel, tsim siv ib zaug - hla ncaj seam submerged arc vuam txheej txheem, muaj qhov tsawg kawg nkaus tawm los ntawm 275MPa thiab zoo heev weld kev ncaj ncees. Nrog nws cov khoom siv sib xws, siab zoo- muaj peev xwm thiab kev tswj xyuas qhov tseeb, cov khoom no tau siv dav hauv cov kav dej, kev tsim cov qauv kev txhawb nqa, kev thauj mus los ntawm cov kua dej thiab lwm yam, thiab tshwj xeeb tshaj yog tsim nyog rau kev ua haujlwm siab nrog cov kev xav tau siab rau lub zog thiab vuam zoo.

S275JR Kub- dov LSAW Welded Hlau Yeeb Nkab Kev Kho Mob:

Kev kho saum npoo ntawm S275JR longitudinal submerged arc welded steel yeeb nkab aims txhim kho nws cov corrosion kuj thiab kev pab cuam lub neej. Cov txheej txheem tseem ceeb muaj xws li:

1. Kev tu yooj yim: Ua ntej, txhaj tshuaj blasting lossis sandblasting yog siv kom huv si tshem tawm oxide nplai, vuam slag, thiab xeb los ntawm cov yeeb nkab steel nto, ua kom huv si "txheej txheem qauv" nto nrog ib qho kev ntxhib los mos los txhim kho txheej adhesion.

2. Kev Tiv Thaiv Txheej Txheem Txheej Txheem: Cov txheej txheem sib txawv yog tom qab siv nyob ntawm qhov chaw thov. Cov txheej txheem muaj xws li tshuaj tsuag xeb -cov roj tiv thaiv lossis epoxy zinc- nplua nuj primer. Lub qub yog tsim rau luv luv -lub sij hawm xeb tiv thaiv thaum lub sij hawm cia thiab tsheb thauj mus los, thaum lub sij hawm tom kawg muab nruab nrab - mus rau ntev - lub sij hawm corrosion los ntawm cathodic tiv thaiv zinc hmoov.

3. Heavy-Lub Luag Haujlwm Tiv Thaiv Kev Tiv Thaiv: Rau faus, subsea, lossis ib puag ncig corrosive heev, ntau- txheej tiv thaiv yog ua haujlwm, xws li peb- txheej polyethylene (3PE) lossis epoxy asphalt coatings. Cov txheej txheem no sib txuas cov kev tiv thaiv corrosion ntawm epoxy primer, lub zog sib txuas ntawm cov nplaum, thiab kev tiv thaiv txhua yam ntawm polyolefin txheej txheej, tsim cov tshuaj tiv thaiv qhov kawg.
