Key details of EN 10219 SSAW steel pipe

EN 10219 is a European standard developed by the European Committee for Standardization (CEN) for cold-formed welded structural steel pipes. Widely used in construction, infrastructure, water transmission, and industrial sectors, this standard ensures that pipes meet strict requirements for mechanical strength, corrosion resistance, and structural integrity.

These pipes are typically made from non-alloy and fine-grain structural steels, offering an excellent strength-to-weight ratio, superior weldability, and long-term durability. Spiral welded pipes manufactured under EN 10219 are especially suitable for large-diameter and high-pressure applications, making them ideal for bridges, offshore platforms, and deep foundation piling.

This guide outlines the key features of EN 10219 spiral submerged arc welded (SSAW) steel pipes.

Why Choose EN 10219 Spiral Welded Pipes?

EN 10219 spiral welded pipes offer a combination of performance, reliability, and cost-efficiency, making them a preferred choice in demanding structural and infrastructure projects. Key benefits include:

Superior Strength and Durability
Engineered for structural use, these pipes provide high mechanical strength and long-term performance under stress.

Cost-Effective for Large Diameters
The spiral welding process enables economical production of large-diameter pipes, reducing material and installation costs.

Ideal for Bridges, Piling, and Offshore Structures
Their high load-bearing capacity and corrosion resistance make them well-suited for critical applications such as marine platforms, foundation piling, and bridge supports.

Efficient Production of Long Pipe Lengths
Spiral forming allows for continuous manufacturing of extended pipe lengths, minimizing weld joints and installation time.

EN 10219 Spiral Welded Pipe: Welding Process & Manufacturing

The manufacturing of EN 10219 spiral welded pipes adheres to strict quality standards to ensure exceptional structural integrity and compliance with European regulations. The production process involves the following steps:

1. Steel Coil Selection
Premium-grade non-alloy and fine-grain structural steels are chosen in accordance with EN 10219 specifications.
Common material grades include:

S235JRH

S275J0H

S355J2H

S420MH

2. Spiral Forming
Steel strips are fed into a spiral forming machine, where they are shaped into a continuous helical profile.

The spiral geometry allows for uniform stress distribution across the pipe body.

This enhances structural performance under heavy loads and high pressures.

3. Submerged Arc Welding (SAW)
A double-sided submerged arc welding (DSAW) process is used to join the edges:

Delivers deep weld penetration

Ensures high-strength, defect-free joints

Suitable for both internal and external welds

4. Non-Destructive Testing (NDT) & Quality Assurance
A series of rigorous tests verify weld quality and pipe integrity:

Ultrasonic Testing (UT): Detects internal and surface discontinuities

X-ray Inspection: Ensures weld consistency and flaw detection

Hydrostatic Pressure Testing: Confirms the pipe’s ability to withstand internal pressure without leakage or deformation

5. Anti-Corrosion Coating
To enhance longevity and resist environmental exposure, pipes are treated with various protective coatings such as:

Fusion Bonded Epoxy (FBE)

Three-Layer Polyethylene (3LPE)

Galvanized finishes

6. Final Inspection & Certification
Before dispatch, each pipe undergoes a thorough inspection covering:

Dimensional accuracy

Mechanical properties

Surface and coating quality
Pipes are then certified in accordance with EN 10219 and ISO 9001 standards, ensuring full compliance and traceability.
