Overview of API 5L PSL1 Spiral Welded Pipe
API 5L PSL1 Spiral Welded Pipe is a widely used carbon steel pipe designed for oil & gas transmission, water pipelines, and structural applications. It follows the API 5L standard, specified by the American Petroleum Institute (API), ensuring reliable performance, durability, and industry compliance.
API 5L pipes are divided into two product specification levels (PSL):
- PSL1: The basic and most commonly used type for oil, gas, and water transmission pipelines.
- PSL2: A higher-quality version with stricter testing, mechanical properties, and toughness requirements for critical applications.
Key Features of API 5L PSL1 Spiral Welded Pipe
✔ Manufactured using Submerged Arc Welding (SAW) or Helical Submerged Arc Welding (HSAW)
✔ Available in steel grades X42, X46, X52, X56, X60, X65, and X70
✔ Designed for oil, gas, water, and structural applications
✔ Less stringent testing compared to PSL2 but still reliable for general use
✔ Cost-effective alternative to seamless pipes for large-scale projects
In this guide, we’ll explore everything about API 5L PSL1 Spiral Welded Pipes, including manufacturers, specifications, price trends, coatings, applications, and welding processes.
