I-Tubing Pup Joint
I-tubing pup joints isebenza njengengxenye ebalulekile embonini kawoyela negesi, ixhuma izingxenye ezihlukahlukene zamashubhu ndawonye ukuze kwakhiwe ukugeleza okungenamthungo kwamafutha negesi kusuka endaweni yokugcina amanzi kuya phezulu. Lawa majoyinti aklanyelwe ukunikeza ukuguquguquka nokumelana nokucindezela, okuvumela ukuthuthwa okuphumelelayo kwezinsiza ngokusebenzisa umthombo. Ijoyinti le-tubing pup lisebenza njengesixhumi phakathi kwentambo enkulu yeshubhu nezinye izinto zokuqedela, okuqinisekisa ukuvaleka okuqinile ukuvimbela noma yikuphi ukuvuza noma ukulahleka kokukhiqizwa. Ngokukwazi ukuhlalisa amasayizi ahlukahlukene kanye nokucaciswa, amalunga e-tubing pup adlala indima ebalulekile ekwenzeni ukusebenza kahle nokugcina ukusebenza kahle ekukhiqizeni uwoyela negesi.
Amalunga e-tubing pup adlala indima ebalulekile embonini kawoyela negesi, asebenza njengezixhumi phakathi kwezingxenye ezimbili zamashubhu. Lobu bude obufushane beshubhu busetshenziselwa ukulungisa ubude bentambo yeshubhu iyonke noma ukuhlukanisa ingxenye ethile yomthombo. Ngokuvamile zitholakala ngosayizi abahlukahlukene kanye nokucushwa ukuze kuhlangatshezwane nezidingo zokusebenza ezihlukene. Amalunga omdlwane anezimbobo aklanywe anezimbobo ezincane ngobude beshubhu, okuvumela ukugeleza koketshezi kungene nokuphuma emthonjeni. Lo mklamo uwusizo ikakhulukazi lapho isihlabathi noma izinhlayiya eziqinile zidinga ukuhlungwa oketshezini olukhiqiziwe. Ngokusebenzisa amalunga e-pup ane-perforated, opharetha bangavimbela ukuvinjelwa futhi baqinisekise ukugeleza kokukhiqiza okubushelelezi. Ukwengeza, lawa malungu e-pup angafakwa kalula futhi asuswe njengoba kudingeka, anikeze ukuguquguquka nokusebenza kahle ekusebenzeni kwemithombo. Sekukonke, amalunga e-tubing pup, ikakhulukazi lawo anezimbobo, ayizingxenye ezibalulekile ekukhiqizweni komthombo kawoyela negesi, athuthukisa ukusebenza nokusebenza nokuthembeka.
I-API 5CT iyindinganiso ethuthukiswe yi-American Petroleum Institute ebeka imihlahlandlela yokwenziwa nokuhlolwa kwezimpahla ze-tubular ezisetshenziswa embonini, okuqinisekisa ikhwalithi nokuthembeka kwazo.
