The pipe expanding machine is designed due to the insufficiency of large diameter seamless steel tube production and specification. It's a two oil cylinder or four oil cylinder parallel uniform velocity pushing machine, pump station valve table adopts integrated form. Setting the power of medium frequency heating power supply, force, and stroke of oil cylinder according to the outer diameter and length of the pipe.
The pipe expanding machine has the following parts: Main machine, automatic feeding, and unloading material system, hydraulic pump station, medium frequency power supply, adjustable holder of the induction coil.
Our factory independent research and development of automatic hydraulic expanding machine has won the national patent,
Adopt a PLC control system, realize the expansion process automation.
The hydraulic automatic pipe expanding machine can hot expand and manufacture seamless steel pipes of various pipe diameters, and the diameter of the expanded pipe ranges from Φ60 to Φ1420 mm.
The equipment is designed for the expansion and re-use of waste oil pipes and water pipes that have been replaced by oil production plants. It is designed because domestic large-diameter seamless steel pipe production cannot meet market demand. The seamless steel pipe is the raw material for the transportation pipeline of liquid, gas, and other fluids. The hydraulic automatic pipe expansion machine is an equipment for manufacturing seamless steel pipes.
The pipe expanding machine is suitable for oil, natural gas, chemical, electric power, construction, and other industries.
The principle of the pipe expander is induction heating and hydraulic cylinder pushing.
