The induction pipe bending machine uses electric induction heating to bend the workpiece under the condition of local heating. At present, it is widely used in pipeline prefabrication in power, petroleum, chemical, marine, nuclear industry and other engineering fields. There are many types of pipe benders, and induction pipe benders are CNC hydraulic pipe benders.
What are the advantages of induction bending pipes?
1) The pipe bending machine uses this process to avoid the uneven wall thickness of the elbow caused by the convex edge of the pipe wall being stretched and thinned, and the concave edge of the pipe wall being compressed and thickened when the traditional pipe bending process is formed.
2) 180 elbows with a small radius (R≈D) and the thin wall (t/D≈0.015) with uniform wall thickness can be produced, which cannot be achieved by other pipe bending processes.
3) If the design of various process parameters is reasonable, the process can ensure that the wall thickness of each part of the tube bend is always kept constant during the forming process, that is, it is always equal to the wall thickness of the straight tube before deformation.
4) With this process, bends with the same diameter of 45°, 90°, 180°, and other bending angles can be produced on the same horn mandrel at one time, and the production efficiency is high.
