I-Meilong Tube ivelisa ngokukodwa ithubhu engenamthungo kwaye izotywe ngokutsha, ezidityanisiweyo kunye nezotywe ngokutsha ezenziwe nge-austenitic ekwaziyo ukugqwala, i-duplex, i-super duplex stainless steels kunye namabakala e-nickel alloy.Iityhubhu isetyenziswa njengemigca yolawulo lwehydraulic kunye nemigca yokutofa kweekhemikhali ngokukodwa ekukhonzeni i-oyile negesi, ishishini le-geothermal.
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.
