Pipe is a hollow section, no seams around the long bar of steel. Steel hollow section, a large number of pipes used for transporting fluids, such as transportation of oil, gas, gas, water and some solid materials, pipes and so on. Steel pipe and solid steel bar, etc. compared to t91, the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive transmission, bicycle frames and construction using steel scaffolding. The ring with a steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving materials and processing time, such as bearing rings, jack sets, has been widely used to manufacture steel. Steel or a variety of conventional weapons indispensable material t91 alloy, barrel, barrel, etc. to make steel. Steel shapes in different cross-sectional area can be divided into tube and shaped tubes. Because t91 steel at perimeter of equal conditions, the largest area of ??a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the vast majority of pipe is pipe. Alloy pipe weight formula: [(OD - Wall Thickness) * thickness] * 0.02466 = kg / m (weight per meter)
