J55 Oil Casing Production Process

The J55 casing pipe coupling phosphating process adopted by the J55 petroleum casing coupling supplier is chemical degreasing, acidic rust removal, chemical degreasing (secondary) water washing, acid etching, water cleaning, phosphating, deionization Washed, air-dried, inspected, dipped in dehydrated antirust oil. After the phosphating process, the J55 petroleum casing coupling has a significantly improved corrosion resistance, so this process is widely used. In the process of oil and gas drilling and production, a large number of casing and tubing are used, and a J55 petroleum casing coupling is used between each two tubing. Corrosion is also one of the main reasons for tubing Luo Jing. Due to the above reasons, many J55 petroleum casing coupling suppliers are constantly discussing the mechanism of their corrosion, and strive to study the corrosion protection measures, so as to ensure that the safety of production is as large as possible. For J55 petroleum casing coupling suppliers, the application of phosphating process on tubing J55 petroleum casing coupling can achieve the ideal purpose of anti-corrosion, this process can very effectively improve the quality of tubing products.
