Transparent stainless steel wire soft tube DN25 mean what does it mean?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
The development of steel tube production technology began with the rise of bicycle manufacturing industry, 19In the early 20th century oil development, during the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation etc., are promoted in yield and quality varieties, the development of steel tube industry.
The actual size of DN25 is outside diameter 34mm, and the inner diameter varies with the thickness of the pipe wall.Different materials of steel pipe, nominal diameter of the same, then its outer diameter is the same, diameter = outside diameter -2 times, wall thickness.
