GRB Spiral Weld Pipe Manufacturing Process & Quality Control

How Are GRB Spiral Weld Pipes Manufactured?

The manufacturing process of GRB Spiral Weld Pipes is designed to ensure high durability, strength, and precision. Below is a step-by-step breakdown of how these pipes are produced:

1. Raw Material Selection

• High-quality API 5L Grade B (GRB) hot-rolled steel coils are selected based on GB/T9711, API 5L, or ASTM A252 standards.
• The steel undergoes chemical composition analysis to ensure uniform mechanical properties such as yield strength and tensile strength.

2. Pipe Forming & Spiral Welding

• The steel plate is formed into a spiral shape using specialized rolling machines.
• The edges are submerged arc welded (SAW) to create a continuous, high-strength weld seam.
• The welding process ensures full penetration and defect-free welds.

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 water testing to verify leak-proof and structural performance.

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 GRB Spiral Weld Pipes Are Preferred?

✔ Designed for structural, oil & gas, and water transmission applications
✔ Manufactured with advanced welding and heat treatment processes
