1. Txheej txheem cej luam - Vim li cas X65 + 316L Clad Pipe

Rau cov kav dej thauj cov roj av uas muaj cov pa roj carbon dioxide (CO₂) tab sis tsuas yog me ntsis ntawm cov hydrogen sulfide (H₂S) thiab cov chlorides tsawg, cov hlau carbon khov kho corrodes sai, thaum cov hlau tsis xeb 316L khov kho feem ntau tshaj qhov teev tseg thiab kim.

X65 + 316L bimetal metallurgically bonded clad yeeb nkabmuaj qhov chaw nruab nrab zoo tagnrho:

Txheej sab nraud X65muab lub zog siab (yam tsawg kawg nkaus 450 MPa), kev tawg tsis kam, thiab kev tswj siab - raws nraim li API 5L X65 kab yeeb nkab paub txog.

Sab hauv 316L claddingncaj qha kov cov kua dej, tiv taus CO₂ corrosion, oxidation dav dav, thiab cov mob acidic me me.

Ob txheej no sib txuas tas mus li los ntawm kev sib txuas hlau (kev sib txuas kub + kev tsim JCOE). Tsis muaj kev pheej hmoo ntawm lub liner vau, wrinkle, lossis sib cais - tsis zoo li cov yeeb nkab uas tau muab txheej txheem.

Qhov kev sib xyaw ua ke no siv dav hauvcov txheej txheem sau cov roj av qab zib,Cov kav dej CO₂ txhim kho roj rov qab (EOR),cov kab txhaj dej, thiabcov roj thiab cov roj uas muaj chloride tsawg.
