I-API 5CT J55 i-casing ye-oyile kunye negesi

I-J55 API casing okanye i-tubing yinto eqhelekileyo kwi-oyile yokugaya. Ngenxa yomgangatho ophantsi wentsimbi ye-J55,
isetyenziselwa ukukhutshwa kwe-oyile kunye negesi engekho nzulu. Ngenxa yexabiso layo eliphantsi phakathi kwamanye amabanga entsimbi, iyonwabela ngokubanzi
izicelo. I-J55 API casing okanye i-tubing isetyenziswa ngokubanzi ekutsalweni kwegesi yendalo kunye ne-coalbed methane,
kwaye inokufunyanwa ngokuqhelekileyo kumaqula angekho nzulu, kwimithombo ye-geothermal, kunye namaqula amanzi.

Iimpawu ze-API 5CT J55 Casing Tubing

Umphezulu wentambo yokudibanisa kunye ne-API 5CT J55 Casing Tubing kufuneka igudiswe ngaphandle kokukrazula, burr
okanye ezinye iziphene ezinokuthi zibe nefuthe elibi kumandla kunye noqhagamshelwano olusondeleyo.

I-API 5CT J55 Casing Tubing inikezelwa kunye nobude obukhululekile ukusuka kwi-8m ukuya kwi-13m ngesiseko se-SY/T6194-96
eqhelekileyo. Nangona kunjalo, iyafumaneka kwakhona akukho ngaphantsi kwe-6m ubude kwaye ubuninzi bayo kufuneka bungabi ngaphezu kwe-20%.

Ukuguqulwa okukhankanywe ngasentla akuvumelekanga ukuba kuvele kumphezulu ongaphandle we-API 5CT J55 Casing
Ukudityaniswa kwetyhubhu.

Naluphi na utshintsho olunje ngokukrazuka, ukwahlukana, inwele, ukuqhekeka okanye ukhwekhwe akwamkelekanga ngaphakathi nangaphandle.
imiphezulu yemveliso. Zonke ezi ziphene kufuneka zisuswe ngokupheleleyo, kwaye ubunzulu obususiweyo akufanele
ngaphaya kwe-12.5% ​​yobukhulu bodonga lwegama.
