Our Main Products
Oil casing is used to support the wellbore of oil and gas wells
Ensure the normal operation of the entire oil well during the drilling process and after completion. Each well requires several layers of casing depending on the drilling depth and geological conditions.
A Coupling Is A Cylindrical Component Used To Connect Two Threaded Pipes
According to the API standard system requirements, couplings must comply with the thread parameter specifications of 5B standard and form a downhole string system together with tubing, casing, drill pipe, etc.
Thread Protector Is A Protective Device That Protects The Thread Structure
The product forms include caps, bushings, and other types, made of materials such as polyethylene and silicone, with a working temperature range of -50 ℉ to+650 ℉.
