X60 Muab Kauv Submerged Arc Welded Kab Yeeb Rau Roj Pipelines
X60 ssaw kab yeeb nkab, tseem hu ua kauv submerged arc welded pipeline cov yeeb nkab, siv kub-raw cov hlua khi rau cov kav dej. Txoj kev tsim qauv no ua rau cov yeeb nkab tsis tsuas yog muaj zog thiab ruaj khov, tab sis kuj tiv taus xeb thiab kev ntxhov siab. Cov yeeb yam no yog qhov tseem ceeb rauRoj Yeeb Nkab txoj kab, uas feem ntau yog feem ntau raug rau cov xwm txheej hnyav thiab cov xwm txheej siab.

Hydrostatic Kev Ntsuam Xyuas
Ib qho ntawm cov ntsiab lus tseem ceeb ntawmX60Ssaw Kab Yeeb Nkabyog nws lub zog siab. Cov yeeb nkab no muaj tsawg kawg vim muaj zog ntawm 60,000 psi, ua rau nws zoo tshaj rau cov kev xav tau ntawm cov roj thiab roj thauj. Cov txheej txheem vuam kuj tseem ua kom pom tseeb tias cov yeeb nkab muaj cov khaub ncaws zoo sib xws, uas ntxiv tau nws lub zog thiab kev ntseeg tau.
Ntxiv rau lub zog, x60 ssaw kab cov yeeb nkab yog paub rau nws qhov kev ua siab loj thiab kev cuam tshuam tawv. Qhov no txhais tau tias cov yeeb nkab muaj peev xwm tiv cov kev ntxhov siab thiab hom kev thauj mus los thiab kev teeb tsa yam tsis muaj kev ncaj ncees. Qhov no yog qhov tshwj xeeb tshaj yog ib qho tseem ceeb rau cov roj yeeb, uas feem ntau yuav tsum tau hla kev sib cav sib ceg thiab kov yeej ntau yam thaum kev tsim kho.
Tsis tas li ntawd, X60 SSAW kab cov yeeb nkab yog cov xeb zoo-tiv taus, ua rau nws ntev-ntev thiab cov nqi hluav taws xob tau zoo rau cov roj yeeb. Cov txheej txheem vuam tsim cov txheej txheem du thiab cov ntaub ntawv sib luag, txo qhov kev pheej hmoo ntawm corrosion thiab txuas lub neej ntawm cov yeeb nkab. Qhov no yog qhov tseem ceeb rau rojraj dejS, uas tau nthuav tawm cov tshuaj corrosive thiab ib puag ncig uas tuaj yeem ua rau cov khoom lag luam tsis zoo.
Hauv kev tsim kho cov roj pipeline, kev nyab xeeb thiab kev ntseeg tau yog qhov tseem ceeb ntawm qhov tseem ceeb. X60 Ssaw Kab Kab Yeeb Nkab Txhua lub thawv ntawm no, muab cov tshuaj muaj zog, ruaj khov thiab corrosion-resistant kev daws teeb meem uas tuaj yeem tiv thaiv cov roj thiab roj thauj. Nws lub zog siab, kev saib xyuas zoo dua qub thiab kev cuam tshuam nyuaj ua rau nws xaiv txhim khu kev qha rau cov phiaj xwm kev nyuaj tshaj plaws rau cov posts nyuaj tshaj plaws.
Hauv cov ntsiab lus, x60 ssaw kab yeeb yog thawj qhov kev xaiv rau cov roj pipelines vim nws lub zog zoo dua, durability thiab corrosion tsis kam. Nws cov txheej txheem vairal vuam ua rau cov kav dej ua rau cov kav dej uas tuaj yeem tiv thaiv qhov siab thiab muaj kev txhim khu kev txhim khu thiab cov tshuaj uas muaj peev xwm txhim khu kev qha rau cov roj thiab roj kev thauj mus los. Thaum tsim cov roj raj xa roj, xaiv x60 kauv submerged arc welded pipeline yeeb nkab yog qhov kev txiav txim siab los xyuas kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm tag nrho cov haujlwm.
