The EN 10217 standard governs welded steel pipes intended for pressure applications, including boilers, pipelines, and industrial fluid transport systems. Issued by the European Committee for Standardization (CEN), this standard ensures that the pipes meet the required mechanical strength, weldability, and corrosion resistance needed for such critical applications.
While EN 10219 is meant for structural applications, EN 10217 is specifically tailored for pressure-bearing systems. This makes it ideal for use in steam pipelines, gas transportation, and industrial processing plants. The SSAW (Spiral Submerged Arc Welding) variant of EN 10217 pipes is particularly well-suited for large-diameter pipes, offering excellent high-pressure resistance and cost-efficiency, making it a popular choice for industrial and energy infrastructure.
This guide provides an overview of the EN 10217 SSAW steel pipe.

Manufacturing Process of EN 10217 SSAW Steel Pipes
The production of EN 10217 Spiral Welded Steel Pipes adheres to strict quality standards to guarantee high pressure resistance, durability, and compliance with European regulations. Here’s a detailed look at the step-by-step manufacturing process:
Steel Coil Selection
High-quality non-alloy and fine-grain structural steel is selected based on EN 10217 material specifications. Common steel grades used include P235TR1, P235TR2, P265TR1, and P265TR2.
Spiral Forming Process
The steel strip is fed into a forming machine, where it is continuously rolled into a helical shape. This spiral seam design enhances pressure handling capabilities and provides flexibility.
Submerged Arc Welding (SAW)
Double-sided submerged arc welding (DSAW) is employed to ensure robust, durable welds. This welding method guarantees high mechanical strength, uniformity, and resistance to stress.
Quality Control & Testing
Both ultrasonic and X-ray testing are conducted to detect internal and external defects. Additionally, hydrostatic pressure testing is performed to verify that the pipes can endure high operating pressures.
Coating & Anti-Corrosion Treatments
To increase corrosion resistance, the pipes are coated with Fusion Bonded Epoxy (FBE), 3LPE, or zinc coatings.
Final Inspection & Certification
Pipes undergo thorough inspection for dimensional accuracy, pressure resistance, and surface quality. They are certified according to EN 10217 standards and ISO 9001 quality management guidelines.
