The pipe expanding machine is used for seamless hot expandin

interchanged  

The pipe expanding machine is used for seamless hot expanding steel pipe, cold drawn seamless steel pipe, straight seam welded pipe, coil pipe and other hot expanding steel pipe fields  

Now we mainly analyze the cold-drawn seamless steel pipe:  

1, cold drawn seamless steel tube can be made of high precision small batch production.  It can be used for precision cold-drawn seamless tubes with high dimensional accuracy and good surface finish of mechanical structure and hydraulic equipment.  

2, the performance of cold-drawn seamless steel tube is better, the metal can be more dense without welding joints, can withstand greater pressure.  

3, cold drawn precision steel pipe inner hole, outer wall size has strict tolerance and roughness.  

In recent years, the demand for hot expanding steel pipe is increasing because its demand is also increasing.  So our company's three - way machine, groove machine, pipe bending machine and push machine and other technical progress is also in progress.  Welcome new and old customers to order our pipe fitting equipment.
