Production technology of large diameter medium frequency pipe bend

　　Large-caliber medium-frequency pipe bend is made by using medium-frequency induction heating to bend the workpiece under the condition of local heating. The technology of Large-Caliber Carbon Steel Pipe Fitting 90deg 10D Pipe Bend is the most economical and effective technology in all kinds of pipe bend technology. The process of large-caliber medium-frequency pipe bend is to put induction coil on the part of steel pipe to be bended, clamp the pipe head with mechanical rotating arm, and heat the pipe with medium-frequency current in the induction coil. When the temperature of the pipe rises to the plastic state, the pipe is bent by mechanical thrust at the back end of the pipe, and the bended part of the pipe is quickly cooled by coolant.

　　We should select the fitting ring according to the specification of the pipe and make the hydraulic system in the preparatory work. The pipes are in place, the starting and bending points are measured, the clamping fixtures are clamped, the water supply valves are started, and the cooling water jets are checked. If the above mentioned items are normal, induction will be activated. When the pipe bend is heated to the proper bending temperature, the liquid cylinder is fed to the working oil path for propulsion and bending. Observe and check the bending condition, stop the cylinder action immediately after the bending degree is completed, and stop the induction electricity. Close the cooling water, loosen the fastening fixture, or repeat the above steps to pipe bend continuously, or remove the pipe bend.

　　It can be seen that the production process of these large-caliber medium-frequency pipe bend is still very complex, but only through the complex production process, can we produce better quality pipeline products, especially its bending process. If the quality of bending processing is not controlled well, it will certainly have an impact on the quality of pipelines, or even cause problems. The pipeline is damaged, so we must follow the steps to ensure the quality of pipe bend when we produce large caliber medium frequency pipe bend.
