High Frequency Resistance Welded Pipe

Date:2020-04-10    keywords:High frequency resistance welded pipe,welded pipe
High frequency resistance welded pipe is a welding method used to heat the resistance generated by the high frequency current flowing through the continuous contact surface of the workpiece, as long as the top forging force is used to allow the metal of the workpiece to be connected to each other. It is similar to traditional resistance welding, but there are many important differences. High frequency resistance welded pipes have been used in the production of carbon steel welded pipes for more than 40 years. The high-frequency resistance welded pipe has a large power supply. For various materials, the diameter strain and wall thickness steel pipe can achieve a higher welding speed (more than 10 times the arc welding of the large welding speed).

Therefore, due to the high speed of high-frequency welding, the general-purpose steel pipe produced by high-frequency resistance welded pipe has caused difficulty in removing burrs in the welded pipe, which has brought difficulties to the current high-frequency welded steel pipe. One of the reasons that has not been accepted by the chemical and nuclear industries. From welding materials, high-frequency resistance welded pipes can weld different types of
Steel Pipe. At the same time develop new steel plants and develop casting and welding methods. Resistance welded pipe has the advantages of high production efficiency, low cost, material saving, and convenient automation. The main factors affecting the straight seam resistance welded steel pipe: input heat, welding pressure, welding speed, opening angle, position impedance, etc. Widely used in water supply and drainage engineering, oil and gas engineering, etc., can also be used as a pile of pipelines, as a bridge;

Resistance welded pipe is the main type of steel pipe, which has made a significant contribution to China's industrial development, but the current status of China's resistance welded pipe industry is like this. Although the products are widely used, they are still far away from the joint steel pipe, and their output Much smaller than seam steel pipes. At present, China's various production industries are developing rapidly. The demand for industrial land such as seam pipes, oil pipeline transportation, and natural gas pipeline transportation, resistance welded pipes and spiral welded pipes account for most of the market.
