Umgca we-hydraulic we-diameter encinci osetyenziselwa ukusebenzisa izixhobo zokugqibezela i-downhole ezifana ne-surface controlled subsurface safety valve (SCSSV).Uninzi lweenkqubo ezisebenza ngomgca wolawulo zisebenza ngokungaphumeleliyo.Kule modi, umgca wolawulo uhlala ucinezelekile ngamaxesha onke.Nakuphi na ukuvuza okanye ukusilela kukhokelela ekuphulukaneni noxinzelelo lwentambo yolawulo, kusebenze ukuvala ivalve yokhuseleko kunye nokukhusela umthombo.
Iimveliso zetyhubhu zecandelo le-oyile kunye negesi zisetyenziswe ngempumelelo kwezinye iimeko ezindlongondlongo zolwandle kunye ne-downhole kwaye sinerekhodi elide eliqinisekisiweyo lokubonelela ngeemveliso ezihlangabezana neemfuno ezingqongqo zomgangatho wecandelo leoli negesi.
I-Meilong Tube ibonelela ngeetyhubhu ezijijekileyo kuluhlu olubanzi lweentsimbi ezingatyiwa ngumhlwa, iialloyi zenikeli.Sinamava abanzi ekuboneleleni ngemveliso kunye nokusungula izinto ezintsha kweli candelo, ukusuka kwinkqubela phambili yetekhnoloji efunekayo kuphuhliso lolwandle ngo-1999 ukuya kwimingeni yamanzi anzulu namhlanje.
