Ukuhlanganiswa kwe-Tubing
Ishubhu ukuhlangana ziyizingxenye ezibalulekile ekusebenzeni kokukhiqizwa kukawoyela negesi, ezisiza ukuxhumanisa izingcezu ezimbili zamashubhu. Lawa ma-couplings eza ngezindlela ezihlukahlukene nobukhulu obuhlukahlukene, okuqinisekisa ukuthi uphawu oluvikelekile nolungavuzi phakathi kwezingxenye zamashubhu. Lo mshini obalulekile udlala indima ebalulekile ekugcineni ubuqotho bomthombo, ukuvimbela ukuvuza koketshezi nokuvikela imvelo. Ama-coupling amashubhu ngokuvamile enziwa ngezinto zekhwalithi ephezulu njenge-carbon steel, insimbi engagqwali, noma i-alloy steel, edizayinelwe ukumelana nezimo ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu ezivame ukutholwa emithonjeni kawoyela negesi. Ukuqina nokuthembeka kwazo kuzenza zibe yinketho ekhethwayo yokuxhuma izintambo zamashubhu, okuqinisekisa ukugeleza okushelelayo nokusebenza kahle kawoyela negesi phezulu. Sengiphetha, ukuhlanganisa amashubhu kuyizinto ezibalulekile embonini kawoyela negesi, ezidlala indima ebalulekile ekugcineni ukuphepha nokusebenza kahle kwemisebenzi yokukhiqiza.
Intambo yokuhlanganisa amashubhu iyingxenye ebalulekile embonini kawoyela negesi, ihlinzeka ukuxhumana okubalulekile phakathi kwezingxenye zamashubhu ukuze kuqinisekiswe ukugeleza kwezinsiza okungenazihibe. Lezi zintambo ziklanywe ngokucophelela ukuze zimelane nengcindezi ephezulu kanye nezimo ezimbi kakhulu, njengalezo okuhlangatshezwana nazo ekubholeni olwandle noma emisebenzini yokuqhekeka kwe-hydraulic. Ubunjiniyela obunembile bezintambo zokuhlanganisa amashubhu kubalulekile ukuze kuvinjelwe ukuvuza, ukugcina ubuqotho besakhiwo, nokuqinisekisa ukusebenza kahle kwemithombo kawoyela negesi. Ngaphandle kwezintambo ezithembekile zokuhlanganisa amashubhu, yonke inqubo yokukhipha ingaba sengcupheni yokwehluleka, okuholela ezinkingeni ezibizayo kanye nezinhlekelele zemvelo ezingaba khona. Njengoba ubuchwepheshe buqhubeka buthuthuka, ukuthuthukiswa kwemicu ehlanganisa amashubhu enamandla, ehlala isikhathi eside kubalulekile ukuze kuhlangatshezwane nezidingo ezikhulayo zemboni futhi kuqinisekiswe ukukhishwa okuphephile nangempumelelo kwemithombo kawoyela negesi.
Ukuhlanganisa amashubhu kudlala indima ebalulekile embonini kawoyela negesi, kuhlinzeka ukuxhumana phakathi kwezingxenye ezimbili zamashubhu ukuze kuqinisekiswe ukugeleza koketshezi okungenamthungo. Lokhu kuhlanganisa kubambelela kumazinga athile abekwe yizindikimba ezilawulayo ukuze kuqinisekiswe ukuphepha, ukusebenza kahle, nokwethembeka ekusebenzeni. I-American Petroleum Institute (API) isungule ukucaciswa okujwayelekile kokuhlanganisa amashubhu, ichaza izici ezifana nezidingo zezinto ezibonakalayo, ubukhulu, kanye nemibandela yokuhlola ukusebenza. Ngokunamathela kulawa mazinga, izinkampani zikawoyela negesi zingaqinisekisa ukuhambisana kanye nekhwalithi yokuhlanganisa amashubhu asetshenziswa ekusebenzeni kwazo, kunciphise ubungozi bokuvuza, ukwehluleka, kanye nobungozi bemvelo. Ukwengeza, ama-coupling amashubhu ajwayelekile avumela ukushintshana phakathi kwabakhiqizi abahlukene, okuhlinzeka ngokuguquguquka kwezingxenye zokuthola ngaphandle kokufaka ukusebenza. Sekukonke, ukusungulwa kanye nokulandelwa kokucaciswa okujwayelekile kokuhlanganisa amashubhu kubalulekile ekugcineni ubuqotho bokusebenza nokuphepha ngaphakathi kwemboni kawoyela negesi.
