X60 Kauv Submerged Arc Welded Kab Yeeb Nkab Rau Roj Pipelines
X60 SSAW kab yeeb nkab, tseem hu ua kauv submerged arc welded pipeline yeeb nkab, siv kub dov steel coils ua raw cov ntaub ntawv rau spirally khoov lub sawb rau hauv cov kav dej.Cov txheej txheem tsim khoom no ua rau cov yeeb nkab tsis yog tsuas yog muaj zog thiab ruaj khov, tab sis kuj tseem tiv taus corrosion thiab kev ntxhov siab.Cov yam ntxwv no tseem ceeb heev raucev oil kab, uas feem ntau raug rau ib puag ncig hnyav thiab cov xwm txheej siab.

Hydrostatic Test
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmX 60SSAW kab yeeb nkabyog nws lub zog siab.Cov yeeb nkab no muaj qhov tsawg kawg nkaus lub zog ntawm 60,000 psi, ua rau nws zoo tagnrho rau cov kev xav tau siab ntawm cov roj thiab roj tsheb thauj mus los.Cov txheej txheem kauv vuam kuj ua kom ntseeg tau tias cov yeeb nkab muaj cov phab ntsa tuab, uas ntxiv dag zog rau nws lub zog thiab kev ntseeg siab.
Ntxiv rau qhov muaj zog, X60 SSAW kab yeeb nkab tau paub txog nws cov ductility zoo heev thiab cuam tshuam rau lub zog.Qhov no txhais tau hais tias cov yeeb nkab muaj peev xwm tiv taus cov kev ntxhov siab thiab cov kab mob ntawm kev thauj mus los thiab kev teeb tsa yam tsis muaj kev cuam tshuam nws txoj kev ncaj ncees.Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau cov roj yeeb nkab kab, uas feem ntau yuav tsum tau hla kev nyuaj struts thiab kov yeej ntau yam teeb meem thaum lub sij hawm tsim kho.
Tsis tas li ntawd, X60 SSAW kab yeeb nkab yog cov corrosion-resistant, ua rau nws siv tau ntev thiab muaj txiaj ntsig zoo rau cov roj yeeb nkab kab.Cov txheej txheem spiral welding tsim ib tug du nto thiab zoo ib yam welds, txo txoj kev pheej hmoo ntawm corrosion thiab ncua lub neej ntawm cov yeeb nkab.Qhov no yog qhov tseem ceeb rau rojcov kav dejs, uas raug rau cov khoom corrosive thiab ib puag ncig yam uas tuaj yeem ua rau cov khoom tsis zoo.
Hauv kev tsim cov roj pipeline, kev nyab xeeb thiab kev ntseeg tau yog qhov tseem ceeb tshaj plaws.X60 SSAW kab yeeb nkab zuam tag nrho cov thawv ntawm no, muab cov kev daws teeb meem muaj zog, ruaj khov thiab tiv taus corrosion uas tuaj yeem tiv taus qhov nruj ntawm kev thauj mus los ntawm roj thiab roj.Nws lub zog siab, zoo heev ductility thiab cuam tshuam toughness ua rau nws yog ib qho kev xaiv txhim khu kev qha rau cov kav dej sib tw tshaj plaws.
Hauv cov ntsiab lus, X60 SSAW kab yeeb nkab yog thawj qhov kev xaiv rau cov roj kav dej vim nws lub zog zoo dua, ua haujlwm ntev thiab corrosion kuj.Nws cov txheej txheem kauv vuam tsim cov kav dej uas tuaj yeem tiv taus kev kub ntxhov, nyuaj struts thiab corrosive ib puag ncig, ua rau lawv txhim khu kev qha thiab raug nqi rau kev thauj mus los roj thiab roj.Thaum tsim cov roj pipelines, xaiv X60 kauv submerged arc welded pipeline yeeb nkab yog qhov kev txiav txim siab kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm tag nrho cov haujlwm.
