API-Certified Welded Round Steel Pipe for Oil and Gas Pipeline Transport Applications

Hunan Yige Special Steel delivers API-certified welded steel pipes engineered for critical oil and gas pipeline infrastructure. Manufactured under ISO9004 and ISO14000 standards, these carbon steel conduits ensure reliable transportation of petroleum products under extreme pressure and environmental conditions. With over eight years of industrial expertise, our facility produces pipes meeting rigorous API 5L specifications for pipeline integrity and operational safety.

Core Technical Advantages:

• Pressure Resilience: Hydrostatically tested beyond standard operating requirements
• Corrosion Resistance: Optional external coatings available for harsh environments
• Precision Welding: Longitudinal seam welding with automated NDT verification
• Custom Geometry: Tailored diameter/wall thickness configurations

Performance Specifications:

Note: All pipes undergo dimensional verification, hydrostatic testing, and non-destructive examination. Material traceability documentation provided.

These welded pipes feature consistent metallurgical properties throughout the structure, minimizing weak points in pipeline networks. The manufacturing process includes continuous quality checks from raw material inspection to final packaging. For offshore applications, supplementary cathodic protection compatibility can be engineered upon request.

Operational Benefits:

• Reduced maintenance costs through extended service life
• Compatibility with automatic welding techniques during installation
• Seamless integration with existing pipeline infrastructure
• Compliance with international safety regulations
