Types of Welded Steel Pipes
Welded steel pipes come in various types, including standard welded steel pipes, oxygen-fed steel pipes, electrical conduits, galvanized steel pipes, transformer pipes, and specialized shaped electric welded pipes. These pipes serve different purposes, from general use to specific applications like housing wires or electrical systems.Dimensions and Weights of Low-Pressure Fluid Transfer Welded Steel Pipes
Below is a table that provides nominal diameters, outer diameters, wall thicknesses, and theoretical weights per meter for both regular and thickened tubes. This data helps in selecting the right pipe for specific applications. | Nominal Diameter (mm) | Nominal Diameter (in) | Outer Diameter (mm) | Regular Tube Wall Thickness (mm) | Regular Tube Weight (kg/m) | Thickened Tube Wall Thickness (mm) | Thickened Tube 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 theoretical weight per meter is: **W(kg/m) = 0.02466 × thickness × (outer diameter - wall thickness)**International Welded Pipe Standards
Welded steel pipes follow several international standards depending on their intended use. For instance, ASTM A53, ISO 3183, and EN 10217 are common standards for low-pressure fluid transfer. Each standard specifies requirements for chemical composition, mechanical properties, and testing methods to ensure quality and safety. While the table above provides basic dimensions and weights, it’s important to consult the relevant standards and specifications when selecting welded steel pipes for particular projects. Additionally, visual inspections and non-destructive testing can further verify the integrity of these pipes before installation. For those looking to delve deeper into the specifics of welded steel pipes, reviewing the detailed standards and consulting with industry experts can provide valuable insights into optimal material selection and application.Ferromanganese Alloy,Ferro Manganese,High Carbon Ferro Manganese,Carbon Ferro Manganese
