- PSL2: Higher-quality pipe with improved mechanical properties, tough weld seam requirements, and stricter testing for high-pressure and critical applications.
Key Features of API 5L PSL2 Spiral Welded Pipe
✔ Manufactured using Submerged Arc Welding (SAW) or Helical Submerged Arc Welding (HSAW)
✔ Higher strength and toughness than PSL1 pipes
✔ Designed for oil, gas, and high-pressure fluid transport
✔ Available in steel grades X42, X52, X60, X70, and X80 for different pressure ratings
✔ Strict testing requirements: Charpy impact test, hardness test, and non-destructive inspection

How Are API 5L PSL2 Spiral Welded Pipes Manufactured?
The API 5L PSL2 Spiral Welded Pipe manufacturing process follows strict quality control measures to ensure high strength, durability, and compliance with international standards. Below is a step-by-step breakdown of the production process:
1. Steel Coil Selection
- High-quality carbon steel coils are selected based on API 5L PSL2 material requirements.
- Common steel grades include X42, X52, X60, X70, and X80, with higher grades providing increased strength and pressure resistance.
2. Spiral Forming Process
- The steel strip is continuously fed into a forming machine, where it is rolled into a helical shape.
- The spiral seam provides enhanced strength and flexibility, making it ideal for oil & gas pipelines and industrial applications.
3. Submerged Arc Welding (SAW) Process
- Double-sided submerged arc welding (DSAW) is used to create strong, defect-free welds.
- This welding method ensures deep penetration, uniformity, and stress resistance, making it ideal for high-pressure applications.
4. Quality Control & Testing
- Charpy Impact Testing ensures toughness and resistance to fractures.
- Ultrasonic & X-ray Testing detects any internal or surface defects.
- اختبار الضغط الهيدروستاتيكي verifies the pipe’s ability to withstand high operational pressures.
- Dimensional Inspection ensures straightness, thickness uniformity, and diameter accuracy.
5. Coating & Corrosion Protection
- Pipes can be coated with Fusion Bonded Epoxy (FBE), 3LPE, Bitumen, or Cement Mortar Lining to resist corrosion, moisture, and environmental damage.
6. Final Inspection & Certification
- Every pipe is checked for compliance with API 5L PSL2, ISO 9001, and other relevant quality certifications.
