Types of Welded Steel Pipes Welded steel pipes come in various types, including ordinary welded steel pipes, oxygen-blowing steel pipes, wire conduits, galvanized steel pipes, transformer pipes, electric welded special-shaped pipes, and more. These pipes are widely used in construction, plumbing, and industrial applications due to their strength, durability, and cost-effectiveness. Dimensions and Weights of Low-Pressure Fluid Transfer Welded Steel Pipes The following table provides the standard dimensions and theoretical weights for low-pressure fluid transfer welded steel pipes. The data includes nominal diameter, outer diameter (OD), wall thickness, and corresponding weights in kilograms per meter (kg/m) for both ordinary and thickened tubes. Nominal Diameter OD (mm) Ordinary Tube Thickened Tube (mm) (in) Wall Thickness (mm) Theoretical Weight (kg/m) Wall Thickness (mm) Theoretical Weight (kg/m) 6 1/8 10.00 2.00 0.39 2.50 0.46 8 1/4 13.50 2.25 0.62 2.75 0.73 10 3/8 17.00 2.25 0.82 2.75 0.97 15 1/2 21.25 2.75 1.26 3.25 1.45 20 3/4 26.75 2.75 1.63 3.50 2.01 25 1 33.50 3.25 2.42 4.00 2.91 32 1 1/4 42.25 3.25 3.13 4.00 3.78 40 1 1/2 48.00 3.50 3.84 4.25 4.58 50 2 60.00 3.50 4.88 4.50 6.16 65 2 1/2 75.50 3.75 6.64 4.50 7.88 80 3 88.50 4.00 8.34 4.75 9.81 100 4 114.00 4.00 10.85 5.00 13.44 125 5 140.00 4.00 13.42 5.50 18.24 150 6 165.00 4.50 17.81 5.50 21.63 The calculation formula for the theoretical weight of a welded steel pipe is: W(kg/m) = 0.02466 × thickness × (outer diameter - wall thickness). International Welded Pipe Standards Welded steel pipes adhere to international standards such as ASTM A53, API 5L, and EN 10217. These standards define the material properties, dimensions, and testing requirements to ensure quality and performance in various applications. Understanding these standards is crucial when selecting the right type of welded pipe for a specific project or system.
