Manufacturing Process of Spiral Welded Carbon Steel Pipes in Chinese Factories

Chinese factories follow strict quality control measures to ensure high-performance spiral welded pipes. Below is a step-by-step breakdown of the manufacturing process:

1. Raw Material Selection

• High-quality carbon steel coils (API 5L, ASTM A252, GB/T9711) are selected.
• The steel undergoes chemical and mechanical property testing to meet project requirements.

2. Spiral Welding & Fabrication

• The steel plates are rolled into a spiral shape using automated forming machines.
• The edges are submerged arc welded (SAW) using double-sided automatic welding for strong weld seams.

3. Hydrostatic Testing

• Each pipe undergoes high-pressure hydrostatic testing to check for leaks or structural weaknesses.

4. Non-Destructive Testing (NDT)

• Ultrasonic Testing (UT) – Detects internal defects in the weld seam.
• Radiographic Testing (X-ray) – Used for critical applications requiring 100% weld inspection.
• Magnetic Particle Testing (MT) – Identifies surface cracks and imperfections.

5. Surface Preparation & Coating

• Pipes are cleaned using sandblasting or shot blasting to remove rust and contaminants.
• Protective coatings (FBE, 3LPE, 3LPP, Coal Tar Epoxy) are applied for corrosion resistance.

6. Final Inspection & Packaging

• Pipes are marked, labeled, and bundled for shipment.
• Each pipe is tagged with batch numbers, steel grade, and production details for full traceability.

Why Choose a Certified China Spiral Welded Carbon Steel Pipe Factory?

✔ Ensures compliance with API, ASTM, ISO, and GB/T standards
✔ Mitigates risks of defects, leaks, and failures in pipelines
✔ Guarantees long-term durability and reliability
