I-API 5CT I-Seamless steel casing kanye neshubhu

I-Casing Pipe iyipayipi enobubanzi obukhulu esebenza njengesibambisi sesakhiwo sezindonga zemithombo kawoyela negesi, noma ibhobo. Ifakwa emgodini obhobozayo futhi ifakwe usimende ukuze kuvikelwe kokubili ukwakheka komhlaba ongaphansi kanye nomthombo ukuthi ungabhidliki futhi uvumele uketshezi lokumba lujikeleze futhi lukhishwe. Amapayipi e-Steel Casing anodonga olubushelelezi namandla amancane okukhiqiza angama-35,000 psi.

Isikhwama sikawoyela esijwayelekile se-API 5CT sidlala indima ebalulekile ekuvimbeleni umthombo kawoyela ukuthi ungalinyazwa ungqimba lukawoyela ongashoni nokusekela ukuthuthwa kukawoyela negesi. Ngaphezu kwalokho, ipayipi le-casing lingasekela isisindo sesendlalelo se-wellhead ukuvimbela ukuwa. Ipayipi le-API 5CT casing liqinisekisa ukuqhubeka kahle kwayo yonke inqubo yokumba, ngemva kwalokho, ukuthutha uwoyela negesi ukusuka ekubhobozeni kuya emhlabathini.
