What are the current status of china stainless steel welded pipe

What is the development of  china stainless steel welded pipe ? With such questions, let us discuss together. In recent years, China's stainless steel welded pipe applications are becoming more and more popular, the most obvious of which is the use of stainless steel welded pipes for civilian drinking water, while stainless steel welded pipes gradually replace stainless steel seamless pipes are increasingly used in the heat exchanger industry.


First of all, the stainless steel welded pipe is 30% lower than the cost of the seamless pipe. In particular, the “welding” and “cold rolling” stainless steel pipe production process adopted in China in recent years, with the cold-rolled coil plate being slit and formed according to the specifications, after multiple shots The argon arc welding machine is welded into a tube, and then cold-rolled (pulled), so that the performance indexes of the weld can be basically consistent with the base metal, and the product quality is obviously improved. As a result, the advantages of using stainless steel welded pipes to replace stainless steel seamless pipes are becoming more and more obvious.



Secondly, stainless steel welded pipes produced in China are not only due to low labor costs, but also have their own advantages in the production process. In the production process of stainless steel welded pipe, the pipe body will be uniformly extruded, and then subjected to online bright solid annealing annealing, the surface becomes very smooth, and the smooth surface is not easy to scale, and has anti-fouling function. This is beneficial to heat dissipation and does not require frequent cleaning, saving time and effort and saving money. It is also quite simple for the process. Once the mold is sized and the raw material is cut to size, all the welded pipes will be fully automated.


What are the current status of stainless steel welded pipes produced in China?

Industrial welded pipes, such as pipes for chemical machinery and pipes for heat exchangers, can only be produced by a few manufacturers, and the production capacity is seriously insufficient. In addition, because of the strong demand in the domestic and foreign markets, many products are in short supply, making most companies not spending extra time. In terms of production technology, more is to produce products for delivery as soon as possible. Therefore, we often see that some of the welded pipes are not subjected to pickling, passivation, sand blasting, annealing, etc. after the completion of production. Of course, this situation also appears to require product quality in actual use. High has an inseparable relationship.


Then, is China's stainless steel welded pipes mainly exported to those countries?

In fact, this problem is very simple. First of all, because of the low cost and low price of stainless steel welded pipe, its quality requirements are not high when it is used. This is undoubtedly a very happy thing for some developing countries. Because their national strength is not strong, and their productivity is low, most of them rely on imports, and China just fills in this blank market. The major developing countries today are India, Vietnam, Pakistan, Thailand, Myanmar, Laos, and most of Africa.


In short, China's stainless steel market has broad prospects, and China's stainless steel welded pipe production technology needs to be improved. However, there are also a large number of companies in China that are at the forefront of technology. They develop and improve the technology of steel pipes to produce the best stainless steel seamless pipes and stainless steel welded pipes. I believe that we can catch up with the quality of Europe and the United States. Among them, we often have enterprises, Yongxing Special Stainless Steel Co., Ltd, Ruipu technology Group, baowu steel group, wenzhou zheheng steel industry ,etc.
