Production and Manufacturing Process of Oil Casing Couplings

The design of the tubing coupling is mainly from the perspective of changing the structure of the coupling. The main purpose is to develop the anti-corrosion tubing coupling. It is important for the coupling of the tubing and the connecting part of the coupling. It is the role of protection. The use of the tubing coupling can achieve a very strong sealing effect on the welded portion between the oil pipe and the thread at both ends of the connection of the tubing coupling, and also the prevention of the inside and outside of the coupling Corrosion treatment process. The use of the tubing coupling is more operative and practical in the field, and the coupling is required after the coupling is unloaded after the use is completed.The thread is very complete, and there is no obvious corrosion phenomenon, which completely solves the problem of petroleum construction. It is a long-term and very difficult problem in the corrosion application in the repair of the coupling between the oil pipe and the oil pipe. The technical content is relatively high, and the value of use is also very high, which can extend the service life of the casing pipe and the tubing coupling, thereby reducing the production cost and greatly improving the oil and gas well recovery.

The J55 oil casing coupling phosphating process adopted by J55 oil casing coupling supplier is: chemical degreasing, acid descaling, chemical degreasing (secondary) washing, acid etching, water washing, phosphating, Deionized water washing, air drying, inspection, dipping and dehydrating anti-rust oil. The J55 oil casing coupling that has undergone the phosphating process has a very significant improvement in corrosion resistance, so the process is widely used. In the oil and gas drilling process, a large number of casings and oil pipes are used, and a J55 oil casing coupling is used between every two pipes. The corrosion of the oil and gas pipes by the carbon dioxide gas in the oil well is very serious. Corrosion is also one of the main causes of tubing damage. Due to the above reasons, many J55 oil casing coupling suppliers continue to explore the mechanism of corrosion, and strive to study anti-corrosion measures, in order to ensure that safety production is as large as possible. For the J55 oil casing coupling supplier, the application of the phosphating process on the tubing J55 oil casing coupling can achieve the ideal anti-corrosion purpose, which can effectively improve the quality of the tubing product.
