API 5CT P110yog qhov siab - lub zog qhab nia ntawm casing thiab tubing yeeb dav siv nyob rau hauv cov roj thiab roj kev lag luam, txhais los ntawm tusAPI Cov Lus Qhia Txog 5ct(American Petroleum lub koom haum). Nws yog ib qho kev tso tawm thiab tempered steel, muab qhov tsawg kawg nkaus lub zog ntawm 110,000 psi (758 MPa), ua rau nws haum rau qhov tob, siab} qhov zoo} qhov dej siab.
Cov yam ntxwv tseem ceeb & kev siv
Lub zog siab:Nws thawj qhov txiaj ntsig yog nws cov txiaj ntsig zoo lub zog, uas tso cai rau nws tiv thaiv cov neeg kho tshuab siab thauj khoom hauv cov dej sib sib zog nqus.
Tsis -} Tshum Kev Pab: P110 feem ntau tsis pom zoo rau Sour kev pabcuam(Ib puag ncig muaj cov sulrodide (h₂s) tshwj tsis yog pom zoo tshwj xeeb los ntawm tus neeg yuav khoom thiab chaw tsim khoom nrog kev sim ntxiv. Nws yog qhov raug rau sulfide kev ntxhov siab tawg (SSC).
Cov Kev Siv Cov Ntaub Ntawv Feem Ntau:
Ntau lawm lub yees Casing hauv kev sib sib zog nqus ntsug.
Nruab nrab / cov tswv yim dab tsi hauv cov ntawv xav tau.
Nto casing hauv high - siab cov cheeb tsam.
Nws feem ntau siv nyob rau hauv tob, siab - qhov siab, tab sis tsis {1} corrosive (qab zib) ib puag ncig.
