Spiral steel pipes belong to the category of welded pipes. Spiral welded steel pipes are also spiral steel pipes, but the names are different. In fact, they are all types of welded pipes. The application of spiral welded steel pipes can be traced back to the beginning of the last century. It has a history of nearly 100 years. First, the Germans invented the two-roll oblique piercing machine in 1885, and then invented the periodic tying machine in 1981; Tiffel invented the automatic pipe tying machine (also known as the head tying machine), and began to form the modern spiral steel pipe industry.
So when was the spiral steel pipe in our country used? In the 1970s, spiral steel pipes and welded pipes were keeping pace with each other, and the world’s production of spiral steel pipes was increasing at a rate of more than 5% per year. After 1953, China attached great importance to the development of the spiral steel pipe industry, and has initially formed a production system for rolling various large, medium and small pipes.
Large-diameter spiral welded steel pipes have also developed and grown, and today they have been widely used in municipal, industrial and mining enterprises for water supply, drainage, sewage treatment, mud transportation, marine water transportation; gas, steam, liquefied petroleum gas transportation.
