Tube expander

Our factory produce hot expanding pipe mill is mainly confined fluid transport high-frequency welded steel pipes with spiral seam is based on hot-rolled steel strip for tube volumes, often warm spiral shape, using high frequency welding of lap welding method for the pressure fluid transfer high-frequency welded spiral seam steel pipe.

Pipe pressure capability, good plasticity, easy to welding and machining molding; through a variety of strict and scientific examination and testing, the use of safe, reliable, large diameter steel pipes, transmission efficiency, and can save the laying of pipeline investments. Is mainly used for the laying of transmission oil and natural gas pipeline.

Thermal expansion of our machines, IF large bending machine, elbow to push the system machines, hydraulic compression tube machine, cold-drawing machine, beveling machines, pipe mill machine, Three cold-drawing machine
