720mm Carbon Steel Pipe Expanding Machine 3 - 24m Length Large Working Trip 110mm

Used for produce diameter of 720mm carbon steel and alloy steel pipe hot induction tube expander

Work flow of tube expanding machine
When expanding the pipe of the expanding machine, the movement of the pipe adopts the translation mode, which is stable and accurate and does not damage the pipe.This machine adopts the heating mode of hot air circulation and is double-heating, and each heating furnace is equipped with multi-grade heating furnace core.The forming method adopts the qualitative method of shaping the inside of the reaming head and adding external pressure, and the size of the tube mouth is accurate. The machine is equipped with the transfer switch of expanding solvent-based socket (straight port) and expanding elastic seal ring type socket socket (R port) on the control panel.And the R mouth is divided into the way of rising block first and rising block after rising.The choice of tube expanding mode is very convenient and the process is adaptable.
