Tubing thiab Casing Coupling
Casing coupling yog ib tug luv luv yeeb nkab siv nyob rau hauv txuas ob casing kav uas muaj threads.Cov yeeb nkab coupling muaj cov xov sab hauv machined kom phim cov xov sab nraud ntawm cov pob qij txha ntev ntawm casing.Ob lub pob qij txha ntawm cov kav dej yog ntsia hlau rau hauv qhov kawg ntawm lub casing coupling.Los ntawm lawv lub zog tuaj yeem ua los ntawm tib qib ntawm cov hlau zoo li lub casing.Tag nrho cov couplings yog tsim nyob rau hauv raws li API 5CT specification ntawm qhov tseeb tsab.
Properties ntawm Casing Couplings:
♦ Cov khoom ntawm casing couplings yog H40, J55, K55, M65, N80-1, N80Q, L80, C95, T95 thiab P110 qib steel nrog zoo thiab kev ua tau zoo;
♦ Lub taub sab nraud yog 127mm txog 365.12 hli;
♦ Lub casing couplings xov qauv muaj xws li luv round xov, ntev round thread thiab buttress xov.
Tubing coupling yog ib yam ntawm cov cuab yeej drilling muaj nyob rau hauv cov roj teb.Tubing couplings yog siv los txuas cov kav dej.Hom yeeb nkab txuas no tau daws qhov teeb meem uas cov txuas txuas uas twb muaj lawm yuav tawg vim muaj kev ntxhov siab ntau.Cov roj yeeb nkab kawg thiab cov phab ntsa sab hauv ntawm cov tubing coupling yog txuas nrog threads.Thiab cov roj kav thiab qhov kawg ntawm cov tubing coupling muaj tib hom xov.Nws tsis yooj yim rau tawg rau hom kev sib txuas no thiab cov txiaj ntsig kev sib txuas yog qhov zoo.Cov tubing txuas tuaj yeem zam cov roj zoo txoj hlua tso tawm kev sib tsoo zoo.
Cov yam ntxwv ntawm Tubing Coupling:
♦ Cov khoom ntawm tubing couplings yog H40, J55, N80-1, N80Q, L80, C90, T95 thiab P110 qib steel nrog cov khoom zoo thiab kev ua haujlwm zoo;
♦ Nws yog siv los txuas ob lub kav dej;
♦ Cov tubing txuas xov cov qauv muaj xws li cov xov tsis ntxhov siab thiab chim siab xov;
♦ Lub cheeb txoj kab uas hla ntawm tubing coupling li ntawm 55.88 hli mus rau 141.3 hli;
