Types of Welded Steel Pipes Welded steel pipes come in various types, including standard welded steel pipes, oxygen-blowing steel pipes, wire casing pipes, galvanized steel pipes, transformer pipes, and electric welded special-shaped pipes. These pipes are commonly used in construction, plumbing, industrial applications, and mechanical systems due to their durability and cost-effectiveness. Dimensions and Weights of Low-Pressure Fluid Transfer Welded Steel Pipes The table below provides the dimensions and theoretical weights of low-pressure fluid transfer welded steel pipes, including nominal diameter, outer diameter (OD), wall thickness, and corresponding weight per meter for both standard and thickened pipes. 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 formula for calculating the theoretical weight of a welded steel pipe is: W(kg/m) = 0.02466 × thickness × (outer diameter – wall thickness) This formula helps engineers and technicians estimate the weight of pipes before installation or purchase, ensuring proper material planning and structural integrity. International Welded Pipe Standards Welded steel pipes are manufactured according to international standards such as ASTM A53, API 5L, and EN 10217, which define specifications for materials, dimensions, tolerances, and testing procedures. Adhering to these standards ensures that the pipes meet required quality and safety levels for use in various industries.

After the coating is applied to the surface of the object, the lubricant can float on the surface of the paint film, reduce the surface tension of the coating, lower the friction coefficient of the coating film on the second surface, prevent scratches on the coating film, and improve the operability of continuous industrial coating of the coating.
