API-5L PSL1 Welded Spiral Pipe

Product Type - Steel Pipe

API 5L PSL1 pipes are available in various sizes, grades, and wall thicknesses, and are commonly used in the oil and gas industry for pipeline transportation of hydrocarbons, as well as in other industries such as the chemical and petrochemical industries. PSL1 pipes have fewer testing and inspection requirements compared to PSL2, and they also have less strict chemical and mechanical properties.


  • High Precision Dimension: The carbon steel plate has excellent processing technology good molding and easy welding. Thickened material, stable performance, and high hardness, not easy to rust.
  • Low Friction: Low dissipation factor. More durable than most ordinary domestic bearings. Lower operating costs​
  • Life Is Long: High-quality steel through strict quality inspection, quality control layer-by-layer detection, and reliable quality, long service life.
  • Customization: Drawings and samples can be processed and customized. Conventional large-scale spot, non-standard customization.
