Steel casing yeeb nkab yog ib hom yeeb siv hauv cov roj thiab roj kev lag luam, feem ntau rau kev tsim kho zoo. Nws yog tsim los muab cov qauv kev ntseeg siab thiab txhawb nqa rau qhov chaw ua haujlwm, tiv thaiv kev vau thiab tiv thaiv ib puag ncig ib puag ncig ntawm kev sib kis.
Lub API 5CT Qib muaj nyob rau hauv J55 / K55, N80Q, L80, C90, C [T05, nrog rau cov lus qhia ntxiv rau 13 K.
Hlau Casing Yeeb Nkab
Casing yeeb kab seem yog ib puag ncig, txoj kab uas hla loj, kom tiv thaiv lwm cov khoom siv uas feem ntau yog ua los ntawm cov hlau thiab hlau. Roj dej tau tsim los ua kom muaj zog ntawm lub zog sib txawv ntawm lub zog sab nraud, xws li zuaj, tawg, thiab kev noj nyiaj txiag. Thaum lub sijhawm ua haujlwm zoo, muab pov tseg rau hauv qhov zoo ris, nws yuav tswj lub zoo ris zoo kawg nkaus.
Cov yam ntxwv tseem ceeb ntawm cov hlau casing yeeb nkab:
Khoom: Feem ntau ua los ntawm high - lub zog steel, Casing kav hlau, Casing kav hlau, Cas
Tus qauv: Steel Casing Pipes feem ntau yoog raws li kev lag luam qauv xws li API 5CT, uas qhia meej txog cov roj thiab roj kev lag luam.
