China Spiral Steel Pipe Manufacturing Process & Quality Control

How Are China Spiral Steel Pipes Manufactured?

The manufacturing process of China Spiral Steel Pipes follows strict API 5L, ASTM A252, GB/T9711, and DIN standards to ensure high durability, corrosion resistance, and mechanical protection. Below is a step-by-step breakdown of the production process:

1. Raw Material Selection

• High-quality steel coils (API 5L, ASTM A252, GB/T9711) are selected based on chemical composition and mechanical properties.
• The steel undergoes rigorous testing to verify yield strength, tensile strength, and impact resistance.

2. Pipe Forming & Spiral Welding

• 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 to ensure strong, defect-free weld seams.
• The welding process is continuously monitored for high structural integrity and durability.

3. Hydrostatic Testing

• Each pipe undergoes high-pressure hydrostatic testing to verify leak-proof performance and structural reliability.

4. Ultrasonic & Radiographic Testing

• Non-destructive testing (NDT) is performed to detect internal or external welding defects.
• Ultrasonic, X-ray, and magnetic particle testing ensure the highest quality control.

5. Surface Preparation

• يتم تنظيف الأنابيب باستخدام sandblasting or shot blasting to remove rust, scale, and contaminants.
• Proper surface preparation ensures better adhesion for protective coatings.

6. Coating Application (Optional)

• Fusion Bonded Epoxy (FBE), 3-Layer Polyethylene (3LPE), 3-Layer Polypropylene (3LPP), and Coal Tar Epoxy coatings are applied based on project requirements.
• Coatings provide superior corrosion resistance, UV protection, and extended lifespan.

7. Beveling & Cutting

• Pipes are cut to required lengths using automated machinery.
• The pipe ends are beveled for easy welding and connection.

8. Final Inspection & Packaging

• Pipes are marked, inspected, and bundled according to customer specifications.
• Each pipe is labeled with batch numbers, specifications, and manufacturer details for full traceability.
