Product Description

Seamless Steel Pipe

Seamless Steel Pipe is hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines.Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time, has been widely used to make steel pipe.

hot expanding steel tube

We often say that 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 pipe.

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.
