Description
Carbon Steel Welded Pipes
Carbon Steel Welded Pipes, a cornerstone in industrial and civil engineering, are meticulously manufactured by forming flat steel plates or strips into tubular shapes, which are then joined longitudinally through advanced welding processes. This method results in a product that is not only highly economical but also incredibly versatile, enabling the production of a vast range of diameters and wall thicknesses. Welded pipes are indispensable across numerous sectors, including construction, plumbing, oil & gas, and general industrial applications, where their robust mechanical properties and adaptability are paramount.
Key Features & Advantages
- Cost-Effectiveness: More economical to produce than seamless pipes for many applications, especially larger diameters.
- Versatile Sizing: Capability to produce a wide range of diameters (from small to very large) and various wall thicknesses to meet diverse project needs.
- Excellent Mechanical Properties: Offers high tensile strength, good ductility, and robust resistance to pressure and external forces.
- Easy Fabrication & Installation: Their consistent dimensions and weldability ensure quick and efficient assembly and installation, reducing project timelines.
- Surface Treatment Options: Can be coated internally and externally with various materials (e.g., galvanization, epoxy, FBE) for enhanced corrosion resistance, significantly extending lifespan in harsh environments.
- Fluid Transport Efficiency: Smooth internal surfaces minimize friction, ensuring efficient flow of liquids and gases.
Material Grades & Manufacturing Standards
Our Carbon Steel Welded Pipes are manufactured in strict adherence to international standards, ensuring reliability and compatibility for global projects. Common material grades include, but are not limited to:
- ASTM A53: Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless (Type E – Electric-Resistance Welded, Type F – Furnace Butt Welded).
- API 5L: Specification for Line Pipe (Grades B, X42, X46, X52, X56, X60, X65, X70, etc.), commonly used for oil and gas transmission.
- ASTM A139: Standard Specification for Electric-Fusion (Arc)-Welded Steel Pipe (NPS 4 and Over).
- ASTM A252: Standard Specification for Welded and Seamless Steel Pipe Piles.
- EN 10217: Welded steel tubes for pressure purposes.
- JIS G3444: Carbon Steel Pipes for General Structural Purposes.
- GB/T 3091: Welded steel pipes for low pressure liquid delivery.
The primary manufacturing methods utilized are Electric Resistance Welding (ERW) for smaller to medium diameters and Submerged Arc Welding (SAW) for larger diameters, ensuring strong and consistent weld seams.
Available Specifications & Dimensions
- Outer Diameter (OD): Ranging from NPS 1/2 inch (21.3mm) up to NPS 60 inches (1524mm) and larger for specialized projects.
- Wall Thickness (WT): Available in various schedules (e.g., Sch. 10, Sch. 20, Sch. 30, Sch. 40, STD, Sch. 60, Sch. 80, XS, Sch. 100, Sch. 120, Sch. 140, Sch. 160, XXS) or customized according to client requirements.
- Length: Standard lengths include 6 meters (20 feet) and 12 meters (40 feet), with custom cut lengths available upon request.
- Ends: Plain end, Beveled end (for welding), Threaded & Coupled.
Common Applications
