What is ISO 3183 SSAW steel pipe

ISO 3183 SSAW Steel Pipe is a widely adopted international standard developed by the International Organization for Standardization (ISO). It defines technical requirements for steel pipes used in the oil, gas, and petrochemical sectors, ensuring pipelines meet rigorous standards for mechanical strength, corrosion resistance, and pressure containment.

While ISO 3183 applies to both seamless and welded pipes, spiral welded pipes—also known as SSAW (Submerged Arc Spiral Welded) or HSAW (Helical Submerged Arc Welded) pipes—are especially favored for their cost-efficiency, ability to accommodate large diameters, and excellent high-pressure performance. These pipes are extensively used for long-distance transport of oil, natural gas, water, and other fluids.

Why Choose ISO 3183 Spiral Welded Pipes?

High Mechanical Strength: Ideal for transporting oil and gas over long distances

Cost-Effective for Large Diameters: More economical than seamless alternatives in large-diameter applications

Excellent Transmission Efficiency: Suitable for oil, gas, and water pipelines

Long-Length Fabrication: Easier to produce in extended lengths, reducing joint welding

Manufacturing Process of ISO 3183 Spiral Welded Pipes

ISO 3183 spiral welded pipes are produced through a controlled process that ensures high durability, dimensional accuracy, and compliance with international pipeline standards:

1. Steel Coil Selection

Selected high-strength carbon steel coils conform to ISO 3183 material grades

Common grades include GR B, X42, X52, X60, X70, and X80

2. Spiral Forming

Steel strips are fed into a forming mill and rolled into a helical (spiral) shape

This design enhances pressure-bearing capacity and provides structural flexibility

3. Submerged Arc Welding (SAW)

Double-sided submerged arc welding (DSAW) is used for robust weld strength

Ensures superior mechanical properties and fatigue resistance under stress

4. Quality Testing & Inspection

Non-destructive tests such as ultrasonic and X-ray inspection for defect detection

Hydrostatic pressure testing validates pipe integrity under working pressure

5. Anti-Corrosion Coating

Pipes are treated with coatings such as Fusion Bonded Epoxy (FBE), 3-Layer Polyethylene (3LPE), or cement mortar lining

These coatings improve corrosion resistance and extend pipe service life

6. Final Inspection & Certification

Each pipe undergoes dimensional and visual inspection

Fully certified in accordance with ISO 3183 and ISO 9001 quality management systems
