API 5ct k55 yopanda chitsulo chosungira chubu

API-5CT K55 oilfield casing pipe ndi yofanana kwambiri ndi J55, palibe kusiyana kwakukulu pakupanga mankhwala.
ndi kutulutsa mphamvu, komabe mphamvu yomaliza ya K55 ndi yapamwamba kuposa J55 chitsulo, K55/J55 ndi 655MPa ndi
517MPa motero.

K55 ili ndi kukana kutopa kwamakina komanso kutentha komanso kukana ming'alu kuposa J55. Kupanga bwino kutentha,
khoma lolemera la K55 casing ndiloyenera m'malo mwa J55 casing. Yoyamba ili ndi malo abwinoko oletsa kutopa kwamafuta
kuposa omaliza.

Kuyendera
Zakuthupi zimawunikidwa ndipo kutalika kulikonse kumayesedwa ndi hydrostatically, nthawi zambiri mpaka 3,000 psi mu plain end (unthreaded) chikhalidwe.
Zotsatirazi zawunikidwanso:
Makulidwe
Zolemera
Kuwongoka
Utali
Chimodzi mwazowunikira izi ndikungoyendayenda kutalika konse.
Ngakhale mafotokozedwe onse a American Petroleum Institute (API) ndi kuyesa, zolakwika zina zamachubu zimapezekabe pambuyo pobereka; motero, ena ogwira ntchito
fufuzaninso.

Njira Yoyendera:
Kukula ndi kuyang'ana pamwamba
NDT ndi mayeso okakamiza komanso chiphaso chachitatu
Hydrostatic
Mayeso oyendetsa
Kusanthula kwathupi ndi mankhwala
Kuuma ndi kukakamiza kuyesa.
Mphamvu yamagetsi
