Product Description
API 5L X65 SSAW Spiral Welded Carbon Steel Pipe 219mm-3500mm OD 5.0mm-28mm WT SY/T5037 Oil Gas Water Pipeline
Product Overview

Our API 5L X65 SSAW (Spiral Submerged Arc Welded) carbon steel pipe is engineered for large-diameter, high-pressure pipeline applications. Manufactured to SY/T5037 and API 5L specifications using advanced double-sided submerged arc welding technology, this pipe delivers superior strength (minimum yield 450 MPa) and reliability for critical infrastructure projects.

Product Features
  • Spiral Welding Technology: Continuous spiral forming allows production of large-diameter pipes with excellent roundness and straightness
  • X65 High Strength Grade: Minimum yield strength of 450 MPa (65 ksi) for high-pressure transmission pipelines
  • Extra-Large Diameter Range: OD from 219mm to 3500mm covers all major pipeline specifications
  • Double-Sided Welding: Internal and external submerged arc welding ensures full penetration and defect-free joints
  • Long Length Capability: Available in lengths up to 24 meters to reduce field welding joints
Applications
  • Long-distance oil and gas transmission pipelines
  • Water supply and sewage treatment mains
  • Offshore and subsea pipeline projects
  • Structural pipe piling and foundation engineering
  • Petrochemical and refinery process piping
Quality Assurance

Comprehensive testing includes 100% hydrostatic pressure test, radiographic (X-ray) weld inspection, ultrasonic testing, mechanical properties testing (tensile, yield, elongation, impact), chemical analysis, and dimensional verification.

Full Mill Test Certificate (EN 10204/3.1) provided. Third-party inspection by SGS, TUV, BV, or Lloyds available.
Packaging & Delivery

Standard shipping package with plastic end caps, bundled and secured with steel straps, waterproof wrapping for ocean transport. Delivery within 15-30 workdays from order confirmation.
