 The fluid tube is a hollow cross section, from start to finish weld steel pipe. Steel hollow sections, stacking machine, a large number of pipe conveying oil, gas, gas, water and some solid materials, pipes for conveying fluids. Such as steel pipe and round bar of solid steel compared to the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, diffusion and permeability, such as drill pipe , automotive drive shafts, bicycle frames and construction using steel scaffolding. 
 The fluid tube for rolling bearing rings, jack, mechanical parts such as barrels, barrel. In accordance with the cross-section shape can be divided into round and shaped. Given the considerations of area and perimeter of the circular area of ??the fluid tube is more practical, can transport more fluid, and uniform circular cross-section inner and outer diameter force. 
 The fluid tube manufacturers manufacturing methods ① general fluid tube temperature below 450 ℃, domestic pipe on the 10th, the 20th of carbon structural steel hot-rolled pipe or cold drawn tube manufacturing. ② high pressure fluid to control the use, often in high temperature and high pressure conditions, the effect of high temperature flue gas and water vapor, the tube would give birth to oxidation and corrosion. Steel pipe with high rupture strength, high resistance to oxidative corrosion and have good organizational stability. 
 Fluid pipe of the implementation of standards for GB/T8163-1999 
 Weight calculation formula: [(OD - Wall Thickness) * Wall thickness] * 0.02466 = kg / m (per meter weight)
