Q: "H2S Service" yog dab tsi thiab nws cuam tshuam rau cov khoom siv yeeb nkab?
A:Kev pabcuam hauv ib puag ncig uas muaj Hydrogen Sulfide. H2S tuaj yeem ua rau Hydrogen-Induced Cracking (HIC) thiab Sulfide Stress Cracking (SSC). Cov kav dej rau qhov kev pabcuam no yuav tsum tau tswj cov chemistry (tsis tshua muaj hardness, tswj S, P cov ntsiab lus), tshwj xeeb huv steelmaking kev coj ua, thiab feem ntau tshwj xeeb kev kho cua sov. Cov qhab nia yuav raug cim raws li "HIC kuaj" lossis "SSC resistant."
Q: Dab tsi yog "Clad lossis Bimetallic Pipe"?
A:Cov yeeb nkab nrog lub hauv paus txheej (piv txwv li, carbon hlau rau lub zog) metallurgically bonded rau ib txheej cladding sab hauv (xws li, stainless hlau 316L los yog alloy 625 rau corrosion kuj). Nws muaj tus nqi -kev tiv thaiv corrosion zoo rau cov kev pabcuam hnyav xws li cov dej ntws uas nqa cov kua qaub.
Q: Dab tsi yog "Lum Pipe" thiab nws qhov tshwj xeeb?
A:Seamless tube (API 5DP), siv nyob rau hauv txoj hlua laum los xa cov dej drilling thiab torque. Nws qhov tshwj xeeb tshwj xeeb yog "Tool Joint" - forged, siab - lub zog alloy steel connector welded rau hauv cov yeeb nkab lub cev kawg, uas yog tuab thiab hnyav dua cov yeeb nkab nws tus kheej kom tiv taus kev hnav thiab kev sib txuas.
Q: Dab tsi yog "Collapse Pressure" rau casing?
A:Lub siab sab nraud ntawm cov yeeb nkab (xws li roj zoo casing -API 5 CT) kev puas tsuaj puas tsuaj. Nws yog ib qho tseem ceeb tsim qauv tswj hwm los ntawm cov yeeb nkab D / t (inch rau thickness piv), yield zog, thiab ovality. Cov qib siab dua (piv txwv li, P110) thiab cov phab ntsa tuab tuaj yeem tiv thaiv kev sib tsoo ntau dua.
Q: Dab tsi yav tom ntej yuav cuam tshuam rau seamless yeeb nkab tshuab?
A:Cov ntsiab lus suav nrog: 1) Kev loj hlob ntawm qib siab dua - qib zog (xws li,API 5L X120, qib Q&T qib siab) rau cov kav xa dej kom zoo dua . 2) Txhim kho corrosion-cov hlau tsis muaj zog (CRAs) rau qhov chaw hnyav dua. 3) Txhim kho qhov tsis zoo- kuaj kev puas tsuaj (xws li Automated UT, Phased Array) rau 100% defect} nrhiav pom) ntawm {7} steel" ntau lawm nrog qis carbon footprint.
