What is Hot Expanded Seamless Steel Pipes

Hot expand seamless steel pipe is by expanding the diameter of pipe to finish processes - thermal expansion process of the production of steel pipe.

The hot expanding steel pipe is 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.

 

So far, the thermal expansion carbon steel pipe production technology is relatively mature, the level of equipment and methods of thermal processing also has made substantial progress. From billet to the basic technological principle is still tube rotary piercing or pressure perforation as a primary means of preparation of the waste pipe, and then by the subsequent thermal expansion of the process to achieve the reduction of wall and expanding.

 

As smelting, rolling pipe main line extension of the thermal expansion pipe, its production and practice has been a very wide range of applications to fill the major steel production at home and abroad the lack of some special models of large-diameter thin-walled steel pipe blank, but improved production technologies, and control various parameters of the thermal expansion pipe accuracy still requires further research and improvement of China's steel enterprises to strengthen cooperation to jointly research study to improve the thermal expansion of steel production standards, in order to further promote the development of China's steel industry.

 

Changsha Xiangjia Metal Materical Co., Ltd. the Steel Pipe Division of ADTO GROUP, is one of the leading manufacturers of steel pipe in China. We specializes in manufacturing seamless steel pipe, ERW steel pipe, square & rectangular steel pipe, OCTG pipe, ect. in various grades and sizes.
