The Cr-Mo alloy steel pipe fittings manufactured to ASTM A234 includes the grades of WP1, WP12 CL1, WP12 CL2, WP11 CL1, WP11 CL2, WP11 CL3, WP22 CL1, WP22 CL3, WP24, WP5 CL1, WP5 CL3, WP9 CL1, WP9 CL3, WP91, WP911, WP92. The BW pipe NM400 steel material fittings can be made from either seamless pipes, or fusion-welded pipes which shall be with filler metal added and shall conform to the chemical requirements of the standard specification.The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the NM400 steel material industry, keep pace with the times, and move towards a new course!The company currently has a number of extended steel processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment, and can provide customers with diversified products and services. In addition, the company has strong technical force, complete production equipment and advanced production technology. The testing methods are perfect and the NM400 steel material product quality is high,NM400 steel material., Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
