Uvavanyo lunokungqinwa kwisiza ngabahloli beqela lesithathu (SGS, BV, DNV).
Olunye uvavanyo luvavanyo lwangoku lwe-eddy, iikhemikhali, ukuthambisa, ukuvutha, ukushuba, isivuno, ubude, ukuqina komgangatho wezinto eziphathekayo.
Ikhoyili yetyhubhu nganye ibubude obuqhubekayo ngokupheleleyo ngaphandle kweentsimbi ze-orbital.
Ikhoyili nganye yetyhubhu ivavanywa nge-hydrostatic ngoxinzelelo olujoliswe kuyo.
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.
I-Meilong Tube yenza i-alloy resistant corrosion hydraulic hydraulic control line tubing imveliso kwiintlobo ngeentlobo ze-oyile ephuma phezulu nerhasi kunye ne-geothermal.I-Meilong Tube inamava abanzi ekuveliseni iityhubhu ezidityanisiweyo ukusuka kwi-duplex, i-nickel alloy kunye namanqanaba entsimbi engatyiwayo ukuya kushishino kunye neemfuno ezingqamene nomthengi.
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.
