X70 Spiral Weld Pipe Manufacturing Process & Quality Control

How Are X70 Spiral Weld Pipes Manufactured?

The manufacturing process of X70 Spiral Weld Pipes follows strict API 5L standards to ensure high durability, strength, and reliability. Below is a step-by-step breakdown of the production process:

1. Raw Material Selection

• High-quality API 5L X70 hot-rolled steel coils are sourced based on API 5L, GB/T9711, or ASTM A252 standards.
• The steel undergoes chemical composition analysis to ensure uniform mechanical properties, including yield strength and tensile strength.

2. Pipe Forming & Spiral Welding

• The steel plate is formed into a spiral shape using advanced rolling machines.
• The edges are submerged arc welded (SAW), forming a continuous, high-strength weld seam.
• The welding process ensures full penetration and defect-free welds, which are essential for oil & gas pipelines.

3. Heat Treatment & Strength Testing

• Pipes undergo heat treatment to improve tensile strength and load-bearing capacity.
• Each pipe is tested for bending strength, impact resistance, and structural integrity.

4. Hydrostatic Pressure Testing

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

5. 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 used based on pipe grade and project requirements.

6. Beveling & Cutting

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

7. Coating & Anti-Corrosion Treatment

• Pipes can be coated with 3LPE, FBE, Epoxy Coal Tar, or Polyurethane coatings to enhance corrosion resistance.

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 X70 Spiral Weld Pipes Are Preferred?

✔ Designed for high-pressure oil & gas pipeline systems
✔ Manufactured with advanced welding and heat treatment processes
✔ High resistance to bending, compression, and environmental exposure
