Kev Ntsuas Hydrostatic

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmX60SSAW kab yeeb nkabyog nws lub zog siab. Cov yeeb nkab no muaj lub zog tsawg kawg nkaus ntawm 60,000 psi, ua rau nws zoo tagnrho rau kev xav tau siab ntawm kev thauj mus los roj thiab roj av. Cov txheej txheem vuam kauv kuj ua kom ntseeg tau tias cov yeeb nkab muaj qhov tuab ntawm phab ntsa sib npaug, uas ua rau nws lub zog thiab kev ntseeg siab ntxiv.

Ntxiv rau qhov muaj zog, X60 SSAW kab yeeb nkab yog lub npe hu ua nws qhov zoo heev ductility thiab cuam tshuam toughness. Qhov no txhais tau tias cov yeeb nkab muaj peev xwm tiv taus kev ntxhov siab thiab kev sib zog ntawm kev thauj mus los thiab kev teeb tsa yam tsis muaj kev cuam tshuam nws qhov kev ncaj ncees. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov kab yeeb nkab roj, uas feem ntau yuav tsum tau hla cov av nyuaj thiab kov yeej ntau yam teeb meem thaum lub sijhawm tsim kho.

Tsis tas li ntawd xwb, cov yeeb nkab X60 SSAW no tiv taus xeb heev, ua rau nws yog ib qho kev daws teeb meem ntev thiab pheej yig rau cov yeeb nkab roj. Cov txheej txheem vuam kauv tsim kom muaj qhov chaw du thiab cov vuam sib xws, txo qhov kev pheej hmoo ntawm kev xeb thiab txuas lub neej ntawm cov yeeb nkab. Qhov no yog qhov tseem ceeb rau rojcov kav dejs, uas raug rau cov tshuaj corrosive thiab cov yam ntxwv ib puag ncig uas tuaj yeem ua rau cov khoom tsis zoo puas tsuaj.

Hauv kev tsim cov kav dej roj, kev nyab xeeb thiab kev ntseeg tau yog qhov tseem ceeb tshaj plaws. X60 SSAW kab yeeb nkab ua tau raws li txhua yam ntawm no, muab cov kev daws teeb meem muaj zog, ruaj khov thiab tiv taus xeb uas tuaj yeem tiv taus kev thauj mus los roj thiab roj av. Nws lub zog siab, kev ua tau zoo heev thiab kev cuam tshuam ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov haujlwm kav dej nyuaj tshaj plaws.

Hauv kev xaus lus, X60 SSAW kab yeeb nkab yog thawj qhov kev xaiv rau cov kav dej roj vim nws lub zog zoo dua, ruaj khov thiab tiv taus corrosion. Nws cov txheej txheem vuam kauv tsim cov kav dej uas tuaj yeem tiv taus qhov siab siab, av nyuaj thiab qhov chaw corrosive, ua rau lawv yog qhov kev daws teeb meem txhim khu kev qha thiab pheej yig rau kev thauj mus los roj thiab roj. Thaum tsim cov kav dej roj, kev xaiv X60 kauv submerged arc welded pipeline yeeb nkab yog qhov kev txiav txim siab los xyuas kom meej tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm tag nrho cov haujlwm.
