Best china piping solution supplier

The development of steel pipe production technology began with the rise of bicycle manufacturing industry, the development of oil in the early 19th century, the manufacture of ships, boilers and airplanes during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of chemical industry and the drilling, production and transportation of oil and natural gas, all of which greatly promoted the variety, production and quality of steel pipe industry Development on. Steel pipe is not only used to transport fluid and powder solids, exchange heat energy, manufacture mechanical parts and containers, but also an economic steel. It can reduce the weight, save 20-40% metal and realize the factory mechanized construction. Making highway bridges with steel pipes can not only save steel and simplify construction, but also greatly reduce the area of protective coating and save investment and maintenance costs. According to the production method, the steel pipe can be divided into two categories: seamless steel pipe and seamed steel pipe. The seamed steel pipe is called straight seam steel pipe for short. The steel pipe can be divided into carbon steel pipe, alloy pipe and stainless steel pipe according to the material (i.e. steel type). Carbon steel pipe can be divided into ordinary carbon steel pipe and high-quality carbon steel pipe. Alloy Steel Pipe can be divided into: low alloy pipe, alloy structure pipe, high alloy pipe, high strength pipe. Bearing pipe, heat and acid resistant stainless pipe, precision alloy (such as kovar alloy) pipe and high temperature alloy pipe, etc.
Size range: seamless from DN15 to DN600 1 / 2 ″ ~ 24 ″; seamed from DN15 to DN1200 1 / 2 ″ ~ 48 ″
