Hot Expanded Seamless Pipe

Hot expanded seamless pipes, which is relatively low density but the contraction of the strong steel pipe (seamless pipe) can be referred to as thermal expansion. A process of skew rolling or drawing method to expand the pipe diameter. Steel pipe thickening in a short period of time, can produce non-standard and special types of seamless tubes with low-cost and high production efficiency, the current international developments in the field of tube rolling.
 
Hot expand pipe is by expanding the diameter of pipe to finish processes - thermal expansion process of the production of steel pipe. Hot expansion pipe are commonly referred to hot expanded seamless steel pipes.
 
Seamless Steel Pipes usually for High, Middle, Low Pressure Boiler.
