Introduction to EN 10219 Spiral Pipe

EN 10219 spiral pipe is a cold-formed welded structural steel pipe designed for construction, piling, offshore structures, and infrastructure projects. Manufactured using the spiral submerged arc welding (SSAW) process, EN 10219 pipes offer high strength, excellent durability, and superior load-bearing capacity.

Compared to ASTM and API standards, EN 10219 focuses on structural applications rather than fluid transportation, making it ideal for civil engineering projects, bridge foundations, and offshore platforms.

Why Choose EN 10219 Spiral Pipe?

✔ Ideal for structural and foundation applications
✔ High strength and excellent load-bearing capacity
✔ Cost-effective alternative to seamless pipes
✔ Available in large diameters for deep foundations
✔ Compliant with European quality standards

In this guide, we will cover EN 10219 spiral pipe specifications, pricing, manufacturing process, key suppliers, and comparisons with other steel pipe standards.

EN 10219 Spiral Pipe vs. ASTM A252 & API 5L: Key Differences

EN 10219 is designed for structural applications, whereas ASTM A252 and API 5L serve piling and oil & gas applications.

الميزة	EN 10219	ASTM A252	API 5L
التطبيق	Structural, piling, offshore platforms	Piling, deep foundations	Oil & gas transmission pipelines
Material	Non-alloy & fine-grain steel	Carbon steel	Carbon steel (various grades)
عملية التصنيع	Welded (ERW, SSAW, LSAW)	Welded (SSAW & LSAW)	Seamless & welded (ERW, SSAW, LSAW)
القوة	High	High	Very High
التكلفة	More affordable	Higher due to structural strength	Higher due to high-pressure applications

Which One Should You Choose?

✔ For structural applications → EN 10219 is the best choice
✔ For deep foundation piling → ASTM A252 is more suitable
✔ For oil & gas pipelines → API 5L is recommended

Cangzhou Spiral Steel Pipes Group manufactures various steel pipe grades to meet different project requirements.

EN 10219 Spiral Pipe Price Per Ton (2025)

The price of EN 10219 spiral pipes depends on factors like diameter, wall thickness, steel grade, and coatings. Below is an estimated wholesale price per ton for 2025:

سُمك الجدار (مم)	سعر الطن (بالدولار الأمريكي)
4 – 6 mm	900−900 – 900−1,200
8 – 12 mm	1,200−1,200 – 1,200−1,500
14 – 25 mm	1,500−1,500 – 1,500−1,900

Factors Affecting Pricing

✔ Steel Grade: Higher strength grades (S355J2H) cost more.
✔ Customization: Coatings, special dimensions, and end finishes increase the price.
✔ Order Quantity: Bulk purchases lower costs per ton.
✔ Shipping Costs: Prices vary depending on destination and freight charges.

EN 10219 Spiral Pipe Coating & Corrosion Protection

Why Is Coating Important for EN 10219 Spiral Pipes?

EN 10219 spiral pipes are primarily used in structural, offshore, and piling applications, where they are exposed to harsh environmental conditions such as moisture, seawater, and soil corrosion. Without proper coating, corrosion can weaken the structural integrity of the pipes, reducing their lifespan and increasing maintenance costs.

Applying a protective coating helps to:
✔ Prevent rust and structural deterioration
✔ Ensure durability in marine and underground environments
✔ Reduce long-term maintenance costs
✔ Improve mechanical strength and impact resistance

Common Coating Types for EN 10219 Spiral Pipes

نوع الطلاء	Best For	مقاومة التآكل	Temperature Resistance	المزايا
Fusion Bonded Epoxy (FBE)	Offshore & underground structures	High	Up to 85°C	Strong adhesion, chemical resistance, smooth surface
3-Layer Polyethylene (3LPE)	Underground piling & foundation projects	Very High	Up to 85°C	Excellent corrosion protection, high impact resistance
3-Layer Polypropylene (3LPP)	Offshore platforms & marine structures	Very High	Up to 140°C	High impact resistance, superior mechanical strength
Coal Tar Epoxy (CTE)	Marine piling & bridge supports	Very High	Up to 100°C	Cost-effective, effective in high-moisture areas
Galvanized Coating	Structural & general piling applications	معتدل	Up to 60°C	Affordable, suitable for general-purpose use

Choosing the Right Coating for Your Project

✔ For offshore and marine piling → 3LPP or Coal Tar Epoxy is best
✔ For underground and foundation piling → 3LPE provides excellent protection
✔ For bridge and general structural piling → FBE or Galvanized Coating works well

Cangzhou Spiral Steel Pipes Group provides customized coating solutions to meet specific project requirements.
