DIN 30670 PE Coated Spiral Weld Pipe Manufacturing Process & Quality Control

How Are DIN 30670 PE Coated Spiral Weld Pipes Manufactured?

The manufacturing process of DIN 30670 PE Coated Spiral Weld Pipes follows strict DIN, AWWA, API 5L, ASTM A252, and GB/T9711 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 carefully selected to meet chemical and mechanical composition requirements.
• The steel undergoes chemical and mechanical 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 advanced forming machines.
• The edges are submerged arc welded (SAW) using double-sided automatic welding to ensure defect-free, high-strength weld seams.
• This welding process ensures full penetration and structural stability, making it ideal for water transmission, oil & gas, and industrial applications.

3. Hydrostatic Pressure Testing

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

4. Ultrasonic & Radiographic Testing

• Non-destructive testing (NDT) is performed to detect internal or external defects in the weld seam.
• Ultrasonic, X-ray, and magnetic particle testing are conducted based on pipe grade and project requirements.

5. Surface Preparation

• The pipe surface is thoroughly cleaned by sandblasting or shot blasting to remove rust, scale, and contaminants.
• Proper surface preparation ensures better adhesion of the PE coating.

6. Polyethylene (PE) Coating Application (DIN 30670)

• Layer 1 (Fusion Bonded Epoxy – FBE): A layer of fusion bonded epoxy (FBE) is applied electrostatically to provide corrosion resistance.
• Layer 2 (Adhesive Layer): A thermosetting adhesive layer is applied to ensure strong bonding between the epoxy and outer polyethylene layer.
• Layer 3 (Polyethylene – PE Layer): A continuous extruded polyethylene outer layer is applied uniformly to provide mechanical protection against impact, soil stress, and weather conditions.
• Thickness Control: The coating thickness is measured to meet DIN 30670 specifications.

7. Beveling & Cutting

• Pipes are cut into 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 requirements.
• Each pipe is labeled with batch numbers, specifications, and manufacturer details for full traceability.

Why DIN 30670 PE Coated Spiral Weld Pipes Are Preferred?

✔ Designed for high-pressure water and oil & gas pipeline systems
