What is a steel pipe?<\/h2><\/div>\n\n\n\n

Steel pipe is a steel material with a hollow cross section whose length is much greater than its diameter or circumference.<\/p>\n\n\n\n

\n

Pipe <\/a>can not only be used to transport fluids and powdered solids, exchange heat energy, and manufacture mechanical parts and containers, but it is also an economical steel material. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20-40% of metal, and realize factory-based mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of \u200b\u200bprotective coating, saving investment and maintenance costs.<\/p>\n<\/div>\n\n\n\n

Production method of steel pipe<\/h2><\/div>\n\n\n\n

Steel pipes are divided into two production methods: seamless steel pipes and welded steel pipes.<\/p>\n\n\n\n

The production process of seamless steel pipes is to pierce solid tubes or ingots into hollow rough tubes, and then roll them into steel pipes of the required size. Different perforation and tube rolling methods are used, which constitute different methods for producing seamless steel pipes. The production process of welded steel pipes is to bend tubes (steel plates or strips) into tubes, and then weld the gaps to form steel pipes. Due to different forming and welding methods, different methods for producing welded steel pipes are formed.<\/p>\n\n\n\n
