Connect the pipeline and maintain good sealing performance; if a certain section of pipeline has problems, it is convenient to replace a certain section of pipeline; butt welding flange has certain technical requirements and technical parameters in production and use, the butt weld of the ring shall be subjected to post-weld heat treatment, and 100% radiographic or ultrasonic flaw detection shall be carried out, and the radiographic flaw detection shall meet the Grade II requirements of JB4730, and the ultrasonic flaw detection shall meet the Grade I requirements of JB4730. Welding flange adopts certain welding standards and technical production and processing, in line with the corresponding national production standards and requirements. The steel plate for the production of butt welding flange shall be tested by ultrasonic inspection without delamination defects to ensure good quality and performance problems, and shall be produced and inspected according to certain quality requirements to ensure that the steel plate produced and used has no quality problems; it shall be cut into strips along the rolling direction of the steel, and welded into a circular ring after bending, and the surface of the steel shall form a circular cylindrical surface. The flange with neck shall not be directly machined from steel plate during the production of the flange. This is the lack of its design: the connection is dynamic, and such as thermal expansion and fluctuation of periodic loads will cause the movement between the flange face, affecting the function of the flange, so that the integrity of the flange is damaged, and eventually lead to leakage. It is impossible for any product to be free from defects, but try to control the deficiency of the product to a minimum. Therefore, the company in the production of flat carbon steel flange as far as possible to improve the performance of the product, so that it plays a big role. The entire device will require great size and weight, which becomes a special problem in the offshore environment, because in this case weight is always the main concern that people must pay attention. The application field of carbon steel flange Carbon steel flange is a kind of flange, which is widely used and promoted in the machinery industry, and has been praised and favored by users. Carbon steel flanges are widely used, and the scope of use is determined according to different characteristics. They are mostly used when the medium conditions are relatively mild, such as low-pressure non-purified compressed air and low-pressure circulating water. Its advantage is price ratio.
