Welded Steel Pipe Is Widely Used, Gradually Occupy The Domestic And International Markets
Wuxi Qianqiao Strip Steel Co.,Ltd | Updated: Jan 03, 2018

With the continuous improvement of product quality, welded steel pipe is not only widely used in the general plumbing and medium pressure piping in various departments of the national economy, but also among the boiler manufacturing, atomic power stations, chemical, construction, machinery manufacturing, oil drilling And high-pressure pipeline transportation. Production of these types of welded pipe, than the average general technical requirements of the tube higher quality requirements more stringent.

However, China's production of welded steel pipe is mainly used for transporting general piping of petroleum, natural gas, chemical industry and town thermal engineering. It seldom sets foot in the blank for large-scale civil construction, oil drilling, boiler and atomic energy industry. This is because: 1, the existing pipe making equipment is outdated and can only produce general-purpose pipes and pile pipes. To produce such high-performance steel pipe as above, it is necessary to make large-scale existing pipe-making equipment and processes The renovation, improve all kinds of testing methods. 2, the production of high-performance steel raw materials shortage. 3, failed to grasp the market dynamics, lack of the necessary funds and technology for the production of high-performance pipe.

At present, the competition among the same industry at home and abroad is fierce. How to make itself an invincible position and at the same time it can penetrate into the international market really requires that courageous entrepreneurs stand to struggle in the forefront of reform. Many domestic manufacturers saw this trend of development. While accelerating the renovation of existing pipe welding equipment, they also paid attention to researching and developing new products and introducing new technologies and equipment. However, this only shows that our work has just begun. In order for welded pipes to occupy domestic and foreign markets, we must also:

In the pipe production process, as long as the welding, the pipe surface will have stress and deformation, but to varying degrees nothing more. Welding pipe in the welding process generated by the welding stress and a variety of deformation, often make the quality of welded products decline, and even cause cracks. Welding deformation caused by weld size, shape changes, such changes beyond a certain value may not be connected with other welded pipe or not enough machining allowance can not be cut.
