Njengoba sonke sazi, uwoyela uphethiloli ucoliswa ku-petroleum. Intengo kaphethiloli iyenyuka kule minyaka, nezindleko zokushayela ziya ngokuya zikhuphuka. Enqubweni yokukhipha uwoyela, kudingeka kufakwe amapayipi amaningi.

Nakhu ukubheka ipayipi:

Ishubhu (I-GB9948-88) iyishubhu lensimbi elingenamthungo elifanele ishubhu yesithando somlilo, isishintshi sokushisa kanye nepayipi endaweni yokuhluza i-petroleum.

Ipayipi lensimbi lokumba i-geological drilling (YB235-70) isetshenziselwa ukumba okuyisisekelo ngomnyango we-geological, ongahlukaniswa ngepayipi lokubhoboza, ikhola yokubhoboza, ipayipi eliwumgogodla, ipayipi le-casing kanye nepayipi lemvula ngokuya ngokusetshenziswa kwalo.

Ipayipi likawoyela liwuhlobo lwensimbi ende enengxenye engenalutho futhi alihlanganisi nxazonke, kuyilapho ipayipi lokuqhekeka likaphethiloli liwuhlobo lwensimbi yesigaba somnotho.

Amashubhu asetshenziswa kakhulu ekwenzeni izingxenye zesakhiwo kanye nemishini njengamapayipi okubhola uwoyela, imiphini yokushayela imoto, amafreyimu amabhayisikili kanye nezikafula zensimbi zokuhambisa izithombe ezakhiweni. Ukusebenzisa i-petroleum cracking tube ukwenza izingxenye zendandatho kungathuthukisa izinga lokusetshenziswa kwezinto ezibonakalayo, ukwenza lula inqubo yokukhiqiza, konga impahla nesikhathi sokucubungula, njengendandatho egoqayo, umkhono kajack, njll., sekusetshenziswe kabanzi ukwenza ipayipi lensimbi. I-petroleum cracking tube noma izinhlobonhlobo zezikhali ezijwayelekile ezibalulekile, umgqomo, umgqomo nokunye ku-petroleum cracking tube ukuze kwenziwe. Ipayipi lokuqhekeka lika-petroleum lingahlukaniswa libe yipayipi eliyindilinga kanye nepayipi elimise okukhethekile ngokuya ngokuma kwendawo ephambanayo. Njengoba indawo yepayipi yokuqhekeka kwe-petroleum inkulu kakhulu enomjikelezo ofanayo, uketshezi oluningi lungathuthwa ngepayipi eliyindilinga.

I-API5CTisikhwama sikawoyela sisetshenziswa kakhulu ukuthutha uwoyela, igesi yemvelo, igesi, amanzi nolunye uketshezi namagesi.

Ingahlukaniswa ibe ipayipi lensimbi engenamthungo kanye nepayipi lensimbi elihlanganisiwe. Ipayipi lensimbi elishiselwe ngokuyinhloko libhekisela epayipini lensimbi elinomthungo oqondile, futhi i-petroleum casing enkulu ngokuvamile ingumthungo oqondile wepayipi wensimbi we-arc wokushisela. Amazwe okusebenza ayinhloko alo mkhiqizo asatshalaliswa kakhulu eMpumalanga Ephakathi, eYurophu naseMelika.I-Api5cti-casing ingahlukaniswa ibe imininingwane engu-R-1, R-2 kanye no-R-3 kuye ngobude. Izinto eziyinhloko B, X42, X46, X56, X65, X70 njalonjalo. Emazingeni okushisa aphakeme ngokwedlulele kanye nendawo enengcindezi ephezulu, ipayipi lempahla ye-petroleum casing linezinzuzo zalo zemvelo ezihlukile. Isikhwama sikawoyela se-Api5ct sisuka ezintweni ezingavuthiwe siye emikhiqizweni ngaphambi kokulethwa kokuhlolwa okuphansi, ukuhlolwa kwe-tensile, ukuhlolwa komthelela, ukuhlolwa kwe-tensile nokunye ukuhlola okuhlobene.
