Use
Precision installation and debugging are required for these bearings. To ensure longevity and performance, follow these guidelines:
1) Keep the bearings and their environment clean, ideally in a closed or semi-closed setting;
2) Use proper tools and heating methods during installation to avoid damage from impact;
3) Ensure proper lubrication with suitable grease or oil;
4) Protect against rust by avoiding damp environments and wearing gloves during handling;
5) Establish daily maintenance procedures;
6) For special conditions like high temperature or speed, consult us for custom solutions.
Storage
Bearings are coated with anti-rust oil and paper at the factory. As long as the packaging remains intact, the quality will be maintained. Store them in a dry place (humidity below 65%, temperature around 20°C), on shelves at least 30 cm above the ground. Avoid direct sunlight and cold walls.

Coupling
Tubing and Casing couplings are the joining of two short length pipe, mainly used for the connection and repair of oil pipe and downhole tools
Tubing and couplings thread types : Non-upset thread(NU), External- upset thread(EU);
Casing and couplings thread types: Long-round thread(LC), Short-round thread(SC), buttress thread(BC)
Grade: K55,J55,N80-1,N80Q,L80-1,P110,etc.
Pup joint
Tubing and casing pup joints are machined according to the latest version of API SPEC 5CT. The steel grade includes J55,K55,N80-1,N80Q,L80-1,P110,etc. There are two types of thread widely used in tubing pup joint namely Non-upset thread(NU), External- upset thread(EU);
Casing and couplings thread types: Long-round thread(LC), Short-round thread(SC), buttress thread(BC).
Our testing and inspection method system is complete, using a whole set of thread instrument to inspect taper, pitch, tooth, height, tooth type,etc. The products have passed the identification of china petroleum pipeline. Quality supervision ,inspection and testing center and gained the unanimous praise from the customers.
