    Steel pipes are not only used to transport fluids and powdered solids, exchange heat, manufacture machinery parts and containers, but also an economical steel. It can reduce weight, save 20-40% of metal and realize industrialized mechanized construction. Making highway bridges with steel pipes can not only save steel and simplify construction, but also greatly reduce the area of protective coatings and save investment and maintenance costs.
