Spirally welded steel pipe is made by coiling and welding of strip steel
Do you know the difference between spirally welded pipe and seamless square pipe?
Different production processes, spiral pipe is welded by coiling strip steel, seamless square pipe is perforated by billet and there is no welding spot on square pipe. The different uses are that the pressure of the spiral tube is not as high as that of the seamless square tube, and the price is different. The productivity of the seamless square tube is low and the productivity of the spiral tube is high. The two same types of seamless square tubes are much more expensive, if not the pressure requirement is not high or the spiral tube is more economical.
Do you know the difference between spiral tube and seamless square tube? Analysts believe that the accelerated recovery of global economic growth is one of the important factors to promote the rebound of the square tube plate. Previously, there was strong short-selling sentiment in the U.S. stock market, but recently, with better-than-expected economic data from the United States, Europe and China, market sentiment has improved.
Spiral tube execution standard and size deviation
The execution standard of spiral pipe is divided into the standard of ministry and the national standard. The spiral pipe of ministry standard is divided into SY/T5037-1999 spiral pipe, GB/T9711.1-1999 spiral pipe, GB/T9711.2-1999 spiral pipe and so on.
The service life of spiral tube has a great impact on the cost of consumer use. So how can we increase the service life of spiral tubes? Experts from spiral pipe manufacturers tell us that the most important factor causing spiral pipe damage is its corrosion. So we need to extend the service life from the angle of avoiding the corrosion of spiral submerged arc welded pipe. The corrosion of spiral pipe has a great relationship with its environment. If there are many corrosive substances in the environment of spiral pipe, it will be seriously corroded and damaged soon.
