I-API yebhokisi yeolingumbhobho wensimbi osetyenziselwa ukuxhasa udonga lweoli yeoli kunye negesi ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwequla lonke leoli ngexesha lokugaya kwaye emva kokugqitywa.

Uvavanyo loxinzelelo lwe-hydrostatic yombhobho we-casing yinxalenye eyimfuneko yenkqubo yokuvelisa umbhobho wentsimbi. Indima yayo kukuvavanya ukusebenza okuchasene nokuvuza kombhobho wensimbi phantsi koxinzelelo oluqhelekileyo lovavanyo kunye nexesha lokulawula. Njengeeradiographs, i-ultrasonics, kunye nezinye iindlela zokubona iziphene, yindlela ebalulekileyo yokuvavanya umgangatho uwonke weetyhubhu zentsimbi.

Inkcazo eyaziwayo kukugcwalisa umbhobho ngamanzi kunye nokuvavanya amandla ayo okugcina uxinzelelo oluchaziweyo ngaphandle kokuvuza okanye ukuphuka phantsi koxinzelelo. Imisebenzi yayo ibandakanya amanyathelo amathathu: ukugungxula, ukuvavanywa koxinzelelo kunye nokulawula amanzi.

Umgangatho we-API 5CT yovavanyo loxinzelelo lwe-hydrostatic:

1. Ixabiso lovavanyo loxinzelelo lwe-hydrostatic lokudityaniswa kunye nombhobho wentambo lelona xabiso liphantsi loxinzelelo lovavanyo lwe-hydrostatic yombhobho wokuphela kweflethi, uxinzelelo loxinzelelo oluphezulu lwe-hydrostatic yoxinzelelo lokudibanisa, kunye nokumelana nokuvuza kwangaphakathi, kodwa uxinzelelo oluphezulu oluqhelekileyo I-69MPa kunye noxinzelelo lubalwe. Ixabiso ngokubanzi lijikelezwe kwi-0.5 MPa ekufutshane.
2. Ngokweemfuno ze-API, isixhobo sokulinganisa uxinzelelo lovavanyo lwe-hydrostatic kufuneka silinganiswe kwiinyanga ze-4 ngaphambi kokusetyenziswa ngalunye.
3. Ukuba umthengi uneemfuno ezizodwa, uxinzelelo oluphezulu lovavanyo loxinzelelo lunokukhethwa.
4. Uvavanyo loxinzelelo lwe-Hydrostatic Ukuvuza sisiseko sokugatywa.
5. Ngaphandle kwalapho kuvunyelwene ngenye indlela phakathi komthengi kunye nomvelisi, uvavanyo loxinzelelo lwe-hydrostatic alufuneki ekudibaniseni iindawo ezingenanto, izixhobo zokudibanisa, izinto ezikufutshane, okanye i-Q125 yentsimbi ye-pup joints.
