API 5CT OCTG Tubing Manufacturer

Kufotokozera Kwachidule:

Machubu a API 5CT OCTG ndi njira yomwe imagwiritsidwa ntchito kutengera mafuta osakanizika kapena gasi wachilengedwe kuchokera kumalo opangira kupita kumalo oyambira kumunda kuti akakonze akamaliza kubowola.Panthawi yochotsa, machubu a OCTG ayenera kupirira kukakamizidwa ndipo ayenera kukhala amphamvu mokwanira kukana katundu ndi mapindikidwe okhudzana ndi kupanga ndi ntchito.Kuphatikiza apo, machubu nthawi zambiri amakula kuti akwaniritse mitengo yomwe ikuyembekezeka kupanga mafuta ndi gasi.Izi ndichifukwa choti ngati chubu ndi yayikulu kwambiri, tidzakhala ndi vuto lazachuma kupitilira mtengo wamafuta ndi gasi wokha, komabe, ngati chubu la API lili laling'ono kwambiri, liletsa kupanga mafuta kapena gasi, ndipo ngati zinthu zikupitilira motere. zidzakhudza momwe chuma chikuyendera pa chitsimecho.Kawirikawiri, machubu amapangidwa mofanana ndi casing, kupatulapo njira yowonjezera yotchedwa "upsetting" yomwe imagwiritsidwa ntchito kukulitsa mapaipi.
