Overview of EN 10219 Spiral Welded Pipe
EN 10219 Spiral Welded Pipe is a European standard for cold-formed welded structural steel pipes, widely used in construction, infrastructure, water transmission, and industrial applications. Governed by the European Committee for Standardization (CEN), EN 10219 ensures that steel pipes meet high mechanical strength, corrosion resistance, and structural reliability.
These pipes are typically made from non-alloy and fine-grain structural steels, offering high strength-to-weight ratios, excellent weldability, and superior durability. Spiral welded pipes under EN 10219 are preferred for large-diameter and high-pressure applications, making them an ideal choice for bridges, offshore structures, and foundation piling.
In this guide, we will cover everything about EN 10219 Spiral Welded Pipes, including manufacturers, specifications, price trends, coatings, applications, and welding processes.

EN 10219 Spiral Welded Pipe Welding Process & Manufacturing
How Are EN 10219 Spiral Welded Pipes Manufactured?
إن EN 10219 Spiral Welded Pipe manufacturing process follows strict quality control measures لضمان high strength, durability, and compliance with European standards. Below is a step-by-step breakdown of the production process:
- Steel Coil Selection
- High-quality non-alloy and fine-grain structural steel is selected based on EN 10219 material specifications.
- Common steel grades include S235JRH, S275J0H, S355J2H, and S420MH.
- Spiral Forming Process
- The steel strip is continuously fed into a forming machine where it is rolled into a spiral shape.
- إن helical seam distributes stress evenly, making it ideal for high-strength structural applications.
- Submerged Arc Welding (SAW)
- Double-sided submerged arc welding (DSAW) is applied, ensuring deep penetration and strong welds.
- This method enhances mechanical strength and prevents defects.
- Non-Destructive Testing (NDT) & Quality Control
- الاختبار بالموجات فوق الصوتية (UT) detects internal and external defects.
- الفحص بالأشعة السينية يضمن weld integrity.
- اختبار الضغط الهيدروستاتيكي verifies that pipes can withstand internal pressure without failure.
- Coating & Corrosion Protection
- Pipes are coated with Fusion Bonded Epoxy (FBE), 3LPE (Three-Layer Polyethylene), or galvanized coatings to prevent corrosion.
- Final Inspection & Certification
- يتم اختبار كل أنبوب من أجل dimensional accuracy, mechanical properties, and coating quality.
- Certified as per EN 10219 and ISO 9001 standards.
