Spiral Welded Pipe Factory Manufacturing Process

Step-by-Step Process Used by Leading Factories

Step	Process Description
1. Raw Material Selection	High-quality steel coils (API 5L, ASTM A252) are selected and tested for strength and durability.
2. Steel Strip Preparation	Steel coils are uncoiled, leveled, and edges prepared for welding.
3. Spiral Forming	Steel strips are fed into a spiral forming machine and shaped into a cylindrical pipe.
4. Submerged Arc Welding (SSAW)	Inside and outside welding is performed using submerged arc welding, ensuring strong weld seams.
5. Non-Destructive Testing (NDT)	Ultrasonic and X-ray testing detects any defects in the welds.
6. Hydrostatic Testing	Pipes are tested under high pressure to check for leaks or weaknesses.
7. Surface Protection & Coating	Pipes are cleaned, shot-blasted, and coated with anti-corrosion materials (FBE, 3LPE, etc.).
8. Final Inspection & Packing	Pipes are measured, labeled, and bundled for shipment.

China Spiral Welded Steel Pipe: Coating & Anti-Corrosion Treatments

Why Are Coatings Essential for Spiral Welded Steel Pipes?

Spiral welded steel pipes are used in various environments, including underground pipelines, offshore installations, and industrial applications. Without proper coatings, these pipes corrode, weaken, and fail prematurely, leading to costly repairs and replacements.

Types of Anti-Corrosion Coatings Used in Spiral Welded Steel Pipes

Coating Type	Best For	Corrosion Resistance	Temperature Resistance	Advantages
Fusion Bonded Epoxy (FBE)	Water pipelines, oil & gas	High	Up to 85°C	Strong adhesion, smooth surface, high chemical resistance
3-Layer Polyethylene (3LPE)	Underground pipelines, oil & gas	Very High	Up to 85°C	Excellent corrosion protection, long service life
3-Layer Polypropylene (3LPP)	Offshore pipelines, high-temperature applications	Very High	Up to 140°C	High resistance to impact, excellent mechanical strength
Coal Tar Epoxy (CTE)	Buried pipelines, marine environments	Very High	Up to 100°C	Effective in high-moisture environments, cost-effective
Galvanized Coating	Structural applications, fencing	Moderate	Up to 60°C	Affordable, durable, suitable for general-purpose use

How to Choose the Right Coating?

✔ For underground pipelines → Choose 3LPE or 3LPP.
✔ For offshore applications → 3LPP or Coal Tar Epoxy is best.
✔ For industrial water pipelines → FBE provides excellent protection.
