Hot Expanded Seamless Steel Pipes

Hot expanded seamless steel pipes Often referred to as hot expanding or thermal expansion,Website:, it is a process of skew rolling or drawing to expand the pipe diameter. Steel pipe of certain thickness with this treatment can produce non-standard and special types of seamless tubes with low-cost and high production efficiency. So far, the thermal expansion technology is relatively mature in the field of carbon steel seamless steel pipe production. Great progress has been made in these years on the level of equipment and methods of thermal processing.
