Oil field steel pipe mainly includes casing, tubing and drill pipe. Petroleum steel pipe thread professional grease is a kind of grease which is coated on the thread surface before the connection of petroleum steel pipe. API divides it into thread grease and storage grease.
Thread grease: thread grease is a kind of grease applied to the connecting thread of steel pipe before making up. It plays a lubricating role during making up. It can resist high internal and external pressure and play an auxiliary sealing role during use.
The failure of petroleum steel pipe, such as sticking thread, leakage of thread, fracture of thread thread, has a very serious impact on the oil well, which may eventually lead to the whole oil well scrapping. As the failure of petroleum steel pipe thread is directly related to the lubrication, rust prevention and sealing performance of the special lubricating grease for petroleum steel pipe thread, the impact of the special lubricating grease for petroleum steel pipe thread on the petroleum exploitation industry is very critical.
