Oil casing; tubing coupling design is mainly from the point of view of changing the structure of the coupling, mainly the development of anti-corrosion tubing coupling, and the important is to protect the tubing coupling and the threaded part of the coupling pipe. The use of tubing coupling can achieve a very strong sealing effect on the two ends of the tubing coupling and the rotating part between the threads, and also take anti-corrosion treatment technology on the inside and outside of the coupling. The operation and practicability of tubing coupling are relatively strong in the field. When the coupling is unloaded after the use is completed, the threads of the coupling are very complete, and there will be no obvious corrosion phenomenon. The problem of oil operation and construction is completely solved. In the process of repairing tubing and tubing coupling, the threads of the coupling are very complete. Corrosion application is a long-term and very difficult problem to solve. Its technical content is relatively high, and the value of use is very high. It can prolong the service life of tubing and tubing coupling, thus reducing production costs and greatly improving oil and gas recovery.
The phosphating process adopted by J55 oil casing coupling supplier is chemical deoiling, acid rust removal, chemical deoiling (secondary) water washing, acid corrosion, water cleaning, phosphating, deionized water washing, air drying, inspection and immersion dewatering rust-proof oil. After phosphating process, the corrosion resistance of J55 oil casing coupling has been greatly improved, so this process is widely used. In the process of oil and gas drilling and production, a large number of casing and tubing should be used, and a J55 tubing coupling should be used between each two tubing. The corrosion damage of carbon dioxide gas in oil wells to oil and gas tubing is very serious, and corrosion is also one of the main causes of tubing luffing. Because of the above reasons, many J55 oil casing coupling suppliers continue to explore its corrosion mechanism, and strive to study anti-corrosion measures, so as to ensure the safety of production as large as possible. For J55 oil casing collar supplier, the application of linking process in J55 oil casing collar can achieve ideal anticorrosion purpose. This process can effectively improve the quality of tubing products.
