J55 API casing los yog tubing yog ib qho tseem ceeb hauv cov roj drilling. Vim tias qib qis steel ntawm J55,
nws yog siv rau ntiav cov roj thiab roj extraction. Vim nws cov nqi qis ntawm lwm cov qib steel, nws nyiam dav dua
daim ntawv thov. J55 API casing los yog tubing yog dav siv nyob rau hauv lub extraction ntawm natural gas thiab coalbed methane,
thiab tuaj yeem pom muaj nyob rau hauv qhov dej ntiav, qhov dej kub hauv qhov dej, thiab qhov dej dej.

API 5CT J55 Casing Tubing Nta
Qhov saum npoo ntawm cov xov txuas thiab API 5CT J55 Casing Tubing yuav tsum du yam tsis muaj kua muag, burr
los yog lwm yam tsis xws luag uas yuav muaj kev cuam tshuam tsis zoo rau lub zog thiab kev sib raug zoo.
API 5CT J55 Casing Tubing muaj qhov ntev ntev ntawm 8m txog 13m raws li SY / T6194-96
cai. Txawm li cas los xij, nws kuj tseem muaj tsis pub tsawg dua 6m ntev thiab nws qhov ntau yuav tsum tsis pub tshaj 20%.
Deformations uas tau hais los saum toj no tsis raug tso cai los tshwm rau sab nrauv ntawm API 5CT J55 Casing
Tubing coupling.
Ib qho kev deformation xws li crease, sib cais, kab plaub hau, tawg los yog scab yog tsis tsim nyog rau ob sab hauv thiab sab nrauv.
nto ntawm cov khoom. Tag nrho cov teeb meem no yuav tsum tau muab tshem tawm tag nrho, thiab qhov tshem tawm qhov tob yuav tsum tsis txhob
tshaj 12.5% ntawm nominal phab ntsa thickness.
