Round 6000mm high ,300mm,400mm,500mm diameter Steel Pipe

hollow section 400mm diameter steel pipe Description

The steel pipe has a hollow section and its length is much larger than the diameter or circumference of the steel.  According to the cross-sectional shape, it is divided into round, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes; steel pipes are not only used to transport fluids and powdered solids, and exchange  Heat energy, manufacturing mechanical parts and containers, it is also an economical steel

The inner and outer surfaces of the pipeline must be smooth, free of cracks, cracks, material coverage, and non-metallic inclusions. After removing the defects generated in the production process, small scratches, bumps, dents, thin layers of welding slag or traces are allowed to prevent the wall thickness from falling to the minimum allowed range. The weld must be compact, continuous, and free of cracks or other defects, which will reduce the weld resistance of the base metal.

Hollow Section Steel Pipe Application

Are destined for carrying out different types of constructions and supporting metalic structures, located inside or outside, related to civil, industrial, commercial and social-cultural constructions.

The use of steel tubes for structural building gratings, columns and mechanical supports reduces weight, saves 20-40% of metal and allows for factory-mechanised construction. Using steel tubes for road bridges not only saves steel and simplifies the construction process, but also significantly reduces the area of protective coverings, saving investment and maintenance costs.
