Thermal Expansion Seamless Steel Pipe

Thermal Expansion Seamless Steel Pipe is often called as the heat expansion tube, the density is low but the contraction strong steel tube, (seamless steel tube) can be referred to as thermal expansion of the tube.Using method of skew rolling or drawing method of expanding tube diameter of a waste pipe finishing process.In a relatively short period of time to make steel tube diameter, it can produce non-standard, special types of seamless tube, and low cost, high production efficiency, is the international development trend in the field of tube rolling.
