Ipayipi elikhethekile likaphethiloli lisetshenziselwa ikakhulukazi ukumba uwoyela kanye nokushayela kahle kwegesi kanye nokudluliselwa kwegesi kanye negesi. Kubandakanya ipayipi lokumba uwoyela, amaphayiphu kawoyela kanye nepayipi lokupompa lamafutha. Ipayipi elidonsa uwoyela lisetshenziselwa ukuxhuma ikholaji yokushayela ku-drill bit kanye nokudlulisa amandla okumba. Ukufaka uwoyela ikakhulukazi kusetshenziselwa ukusekela udonga kahle ngesikhathi sokumba nangemva kokuphothula, ukuze kuqinisekiswe inqubo yokumba kanye nokusebenza okujwayelekile kwawo wonke umthombo ngemuva kokuphothulwa. Ipayipi lokumpompa ikakhulukazi lidlulisela uwoyela negesi kusuka phansi komthombo.

Ukugoqa uwoyelayindlela yokuphila kahle kawoyela. Ngenxa yemibandela ehlukene yezwe, isimo sokuxineka esingaphansi komhlaba siyinkimbinkimbi, sibe tusle, ecindezelayo, ukugoba kanye ne-toryional stress act ku-Pipe Gody, ebeka phambili izidingo eziphakeme ngekhwalithi yokuzibona ngokwayo. Uma ukuqulwa ngokwako kulimele ngesizathu esithile, wonke umthombo ungancishiswa ukukhiqizwa noma ngisho nokushiywa.

Ngokwamandla wensimbi uqobo, amacala angahlukaniswa ngamabanga ahlukile ensimbi, okungukuthiI-J55, K55, N80, L80, C90, T95, P110, Q125, v150, njll. Izimo ezihlukile zemvelo, ukujula kwensimbi nakho kuhlukile. I-Conseng ngokwayo nayo iyadingeka ukuze ibe nokuphikiswa kokugqwala endaweni enenzuzo. Endaweni yezimo eziyinkimbinkimbi zezwe lezomnotho, ukufakwa kudingeka futhi kube nekhono lokumelana nokuwohloka.
