Khoom cim npe

API 5L X65 PSL1 / PSL2 LSAW Carbon Steel Yeeb Nkab yog ib hom carbon steel yeeb nkab uas yog tsim los ntawm steel phaj, muaj ncaj seam ntawm nws nto.Lub sab nraud txoj kab uas hla ntawm nws yog heev loj, mus txog 1500 millimeters.Cov txheej txheem tsim khoom meej malkes nws yog lub cuab yeej zoo tshaj plaws ntawm kev thauj mus los ntawm cov roj thiab roj, uas tau cuam tshuam ntau tus neeg siv khoom thoob plaws ntiaj teb.
Raws li tus neeg muag khoom LSAW zoo heev, peb muaj lub chaw tsim khoom nrog cov neeg ua haujlwm lub luag haujlwm.Ib qho ntawm peb lub tuam txhab qhov zoo yog tias peb muaj lub sijhawm xa khoom sai thiab peb yuav muaj kev ntsuam xyuas loj ntawm txhua yam khoom ua ntej xa lawv.Ntawm, peb ib txwm nco ntsoov ua peb zoo tshaj plaws kom tau raws li peb cov neeg siv khoom xav tau xws li liab qab, dub paiting, Varnishing,3PE tiv thaiv corrosion、 Galvanizedcev capthiab lwm yam.

Txhawm rau tsim kom muaj txiaj ntsig ntau rau cov neeg yuav khoom yog peb lub tswv yim kev lag luam;neeg loj hlob yog peb ua hauj lwm caum rauTuam Tshoj Steel Kab thiab Yeeb Nkab Zeb, Feem ntau cov teeb meem ntawm cov neeg muag khoom thiab cov neeg siv khoom yog vim kev sib txuas lus tsis zoo.Kev coj noj coj ua, cov neeg muag khoom tuaj yeem tsis txaus siab rau cov lus nug uas lawv tsis nkag siab.Peb rhuav tshem cov teeb meem no kom ntseeg tau tias koj tau txais yam koj xav tau rau qib koj xav tau, thaum koj xav tau.Lub sijhawm xa khoom sai dua thiab cov khoom koj xav tau yog peb Cov Cai.

API 5L X65 PSL1 / PSL2LSAW Carbon Steel Yeeb Nkabfeem ntau yog siv nyob rau hauv tej yaam num ntawmroj thiab roj pipeline, nyob rau hauv submarine pipelines, pipelines los ntawm high-altitude zones thiab tuab hauv nroog.

API 5L X65 PSL1 / PSL2 LSAW Carbon Steel Yeeb Nkab yog tsim los ntawm kev tsim cov X65 steel daim hlau rau hauv ib puag ncig cov duab ces vuam cov seam los ntawm cov txheej txheem arc vuam.Hauv kev tsim cov API 5L X65

PSL1 & PSL2 LSAW Carbon Steel Yeeb Nkab, daim hlau ntawm qib X65 yog tsim los ntawm lub tshuab molding rau hauv cov duab puag ncig ces welded los ntawm ob sab submerged arc vuam.

Chaw tsim tshuaj paus: Longitudinally Submerged Arc Vuam

Loj: OD: 406 ~ 1422mm WT: 8 ~ 60mm

Ntev: 3-12M lossis ntev raws li xav tau.
