FAQs for API 5L Welded Pipe
API SPEC 51 refers to the specific requirements and testing procedures outlined in the API 5L standard for welded steel line pipe. Compliance with API SPEC 51 ensures the pipe meets the quality and performance standards necessary for its intended use.
Several welding methods can be used to manufacture API 5L Welded Steel Pipe, including:
Electric Resistance Welding (ERW): Commonly used for smaller diameter pipes.
Submerged Arc Welding (SAW): Suitable for larger diameter pipes and offers high welding speeds.
Double Submerged Arc Welding (DSAW): A variant of SAW that uses two welding arcs for increased penetration and productivity.
Longitudinal Submerged Arc Welding (LSAW): Used for large-diameter pipes and provides excellent weld quality.
Spiral Submerged Arc Welding (SSAW) / Helical Submerged Arc Welding (HSAW): Used for very large diameter pipes.
