Introduction to ISO 3183 Spiral Pipe

ISO 3183 spiral pipe is a welded steel pipe standard for petroleum and natural gas industries, covering seamless and welded pipes for pipeline transportation systems. It is widely used for oil and gas transmission, water pipelines, and structural applications.

Manufactured using the spiral submerged arc welding (SSAW) process, ISO 3183 pipes provide high strength, durability, and resistance to extreme pressure and temperature conditions.

Why Choose ISO 3183 Spiral Pipe?

✔ Compliant with global oil & gas pipeline standards
✔ High strength and excellent pressure resistance
✔ Cost-effective alternative to seamless pipes
✔ Available in large diameters for long-distance pipelines
✔ Custom coatings available for corrosion resistance

In this guide, we will cover ISO 3183 spiral pipe specifications, pricing, manufacturing process, key suppliers, and comparisons with other steel pipe standards.

ISO 3183 Spiral Pipe vs. API 5L & ASTM A252: Key Differences

ISO 3183 is designed specifically for oil & gas pipelines, whereas API 5L and ASTM A252 serve multiple industries, including structural and piling applications.

الميزة	آيزو 3183	API 5L	ASTM A252
التطبيق	Oil & gas transportation pipelines	Oil & gas, structural applications	Piling, deep foundations
Material	Carbon steel (various grades)	Carbon steel (X42 – X80 grades)	Carbon steel
عملية التصنيع	Welded (ERW, SSAW, LSAW)	Seamless & welded (ERW, SSAW, LSAW)	Welded (SSAW & LSAW)
القوة	Very High	Very High	High
التكلفة	Moderate to High	High	More affordable

Which One Should You Choose?

✔ For oil & gas pipelines → ISO 3183 or API 5L is ideal
✔ For structural applications → API 5L is a better option
✔ For piling and foundation projects → ASTM A252 is recommended

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

ISO 3183 Spiral Pipe Price Per Ton (2025)

The price of ISO 3183 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)
6 – 10 mm	1,100−1,100 – 1,100−1,400
12 – 18 mm	1,400−1,400 – 1,400−1,800
20 – 25 mm	1,800−1,800 – 1,800−2,200

Factors Affecting Pricing

✔ Steel Grade: Higher strength grades (L485/X70) 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.

ISO 3183 Spiral Pipe Coating & Corrosion Protection

Why Is Coating Important for ISO 3183 Spiral Pipes?

ISO 3183 spiral pipes are primarily used for oil and gas transmission pipelines, where they are exposed to extreme weather conditions, underground environments, and corrosive substances. Without a proper protective coating, corrosion can weaken the pipes, reduce flow efficiency, and lead to costly repairs or failures.

Applying a protective coating helps to:
✔ Prevent corrosion and rust in harsh environments
✔ Enhance the lifespan of pipelines
✔ Reduce maintenance and operational costs
✔ Improve mechanical strength and impact resistance

Common Coating Types for ISO 3183 Spiral Pipes

نوع الطلاء	Best For	مقاومة التآكل	Temperature Resistance	المزايا
Fusion Bonded Epoxy (FBE)	Oil & gas pipelines, underground applications	High	Up to 85°C	Strong adhesion, chemical resistance, smooth surface
3-Layer Polyethylene (3LPE)	Underground and offshore pipelines	Very High	Up to 85°C	Excellent corrosion protection, high impact resistance
3-Layer Polypropylene (3LPP)	High-temperature pipelines	Very High	Up to 140°C	High impact resistance, superior mechanical strength
Coal Tar Epoxy (CTE)	Marine pipelines, buried pipelines	Very High	Up to 100°C	Cost-effective, effective in high-moisture areas
Galvanized Coating	Structural applications, low-pressure pipelines	معتدل	Up to 60°C	Affordable, suitable for general-purpose use

Choosing the Right Coating for Your Project

✔ For oil & gas transmission pipelines → 3LPE or 3LPP is best
✔ For high-temperature applications → 3LPP provides superior protection
✔ For marine and buried pipelines → Coal Tar Epoxy works well
