Tube expander is used in the production of seamless steel pipe, straight seam welded pipe, coil pipe and so on.Expandable steel tube varieties are: various carbon steel, alloy steel, stainless steel and so on.The patent product set cone die hole enlargement technology, medium frequency induction heating technology, hydraulic technology in one, with the reasonable technique, simple equipment structure, the construction of low energy consumption, low investment, good product quality, wide range of raw materials and products specifications suitability, flexible variable low input of production batch adaptability to replace the traditional steel pipe industry tension dial hole enlargement technology, became the resolve the shortage of large diameter seamless pipe at home and abroad, a series of large and medium diameter welded pipe specification is difficult to complete an important and indispensable production capacity.With the utilization and development of energy from solid (coal), liquid (oil) to gas (natural gas), it is suitable for the steel pipe demand of energy transmission pipeline.Has formed a complete hot - expanding steel pipe processing industry.

Usage of pipe expanding machine: firstly, annealing the copper pipe flaring end and smoothing it with file, then placing the copper pipe in the fixture of corresponding pipe diameter, tightening the fastening nut on the fixture and clamping the copper pipe firmly.
