Seamless tube expanding machine

Seamless tube expanding machine is the main production technology of large diameter steel tube.It has been widely used in military industry, power plant construction, aerospace industry and Marine industry equipment manufacturing industry, making a great contribution to China's steel pipe industry and energy construction.Seamless tube expanding machine equipment is used in the production of seamless steel pipe, straight seam welded pipe, coil pipe and other steel pipe thermal diameter expanding.Expandable steel tube varieties are: various carbon steel, alloy steel, stainless steel and so on.Cold-drawn seamless steel pipe refers to the seamless pipe or seamless finished pipe as raw material, by the cold-drawn (pull) machine drawing processing, the size of the outer diameter of the corresponding mold, the size is relatively precise.(characterized by reduced outside diameter)

Production steps of seamless tube expanding machine: after perforating the pipe -- rolling -- tension reducing machine -- cooling -- straightening -- cutting -- packing -- storage.(the state is continuous operation, and the dimensional precision is normal)

The thermal expansion is made of seamless steel tube as raw material and heated to a certain temperature on the tube expanding machine.(general precision when the outside diameter increases)
