Welded Steel Pipe Is Widely Used In Technology, Quality Has Greatly Improved
Wuxi Qianqiao Strip Steel Co.,Ltd | Updated: Jan 24, 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.

According to the use of points, the general purpose of welded steel pipe and high temperature and pressure with the latter with the tube is often a special alloy steel, weld cracking must be considered and resolved in the welding process and the heat affected zone pipe mechanical properties Welding operations affect the change too much.

According to the pipe wall thickness, the strip made of relatively thin strip of material such as steel strip can be welded by high-frequency welding. Some thin-walled tubes can be welded by shielding gas. The pipe whose wall thickness exceeds 2mm can be arc-welded by hand.

According to the size of the pipe diameter, only a small diameter welding and mechanics can drill into the pipe to implement both sides of the welding. Single-sided welding on the welder technology requirements, can do single-sided welding two forming, through the ball test to ensure that the cross-sectional area through the ability and weld shape are in line with design requirements.

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.
