(Summary description)On October 10, 2012, the world's largest SG/711mm high-frequency straight seam welded pipe production line rolled off the assembly line in a group in Dalian. The offline of this group of the world's largest high-frequency welded pipe units shows that China's large-diameter pipe-making technology has reached the world's advanced level. For this reason, the International Welded Pipe Association sent a congratulatory letter: "The diameter of 711mm is already the largest high-frequency welded pipe, congratulations! "
West-to-East Gas Pipeline, North-South Oil Pipeline, South-to-North Water Transfer, and my country is planning to build pipelines to transport coal and ore to the east. These large-scale pipeline projects that transport various resources over long distances have huge demand for large-diameter, high-safety pipelines , but the pipe-making technology has been mastered by a few developed countries for a long time.
Since the electrothermal conversion efficiency of high-frequency welded pipes can reach more than 90%, coupled with the application of some advanced technologies, high-frequency straight seam welded pipes have become the industrial direction to replace seamless steel pipes and spiral welded pipes because of their safety and stability. This production line is 300 meters long and weighs 2,500 tons. It can produce the world's largest diameter-711 mm welded pipe with the thickest pipe wall; and its design is ultra-flexible, combining three welding methods: high-frequency welding, submerged arc welding, and argon arc welding. , can be used for carbon steel and stainless steel, producing hundreds of specifications of steel pipes. Each change to produce a new type of steel pipe requires only 13 minutes of adjustment.
The group created its own molding method, breaking the monopoly of developed countries for half a century. The high-frequency welded pipe production line with a maximum diameter of 610mm has been the highest specification for decades at home and abroad. The group first broke this specification to 660mm, and now it has broken through to 711mm. In the field of continuous forming straight seam welded steel pipe technology, the group has declared a total of 82 patents and 9 invention patents. The group also extended the protection of patented technologies to developed countries such as Germany, the United States, and Japan
