API 5CT J55 casing yog seamless steel yeeb nkab uas siv los txhawb cov phab ntsa ntawm cov roj av thiab cov roj cua kom paub meej tias qhov dej ntawd khiav haujlwm zoo thaum thiab tom qab cov txheej txheem drilling. Txhua cov roj zoo yuav tsum tau siv ntau cov khaubncaws sab nraud povtseg nyob ntawm qhov txawv drilling qhov tob thiab yam teebmeem ntawm kev lagluam. 5CT seamless casing muaj ib qho chaw zoo nkauj elongation. Tom qab lub voj vias khawb hauv qhov dej, qhov dej yog qhov cemented. Yog li ntawd seamless steel casing yog tsis reusable. Vim li no, cov yeeb nkab yuav siv nyiaj ntau tshaj li 70% ntawm cov roj kav dej.


Cov Khoom: API 5CT casing tube txias dua tom qab tus txheej txheem tempering. Qhov no yuav pab tau rau txoj kev tsis sib haum xeeb kom tsis txhob muaj kev kub ntxhov siab thiab nce kev sib zog, txoj kev quenching yog saws los txo cov teeb meem ntsiab thiab impurities zoo.

Daim ntaub ntawv: J55 casing yeeb nkab yog siv nyob rau hauv lub hauv paus ua haujlwm ntawm ntau cov lag luam xws li roj av, cov pa roj, cov pa roj, dej, thermal zog, dredging engineering etc.
