Spiral Welded (SAW) or Longitudinal Submerged Arc Welded (LSAW) pipes are high-quality products manufactured in accordance with the stringent standards of ISO 3183 and API 5L. They are designed to meet the complex requirements of safe and efficient transportation of liquids and gases in various industrial applications. These pipes are produced by longitudinally or spirally welding steel plates under a submerged flux.

SAW Welded Pipe

• Material: Non-alloy or alloy steel.

• Manufacturing Process: In the SAW process, the welding is done spirally along the length of the pipe under a submerged flux.

• Applicability: Suitable for producing large-sized pipes, especially for large diameters and thicker wall thicknesses.

LSAW Welded Pipe

• Material: Non-alloy or alloy steel.

• Manufacturing Process: In the LSAW process, the welding is done longitudinally along the length of the pipe under a submerged flux.

• Applicability: Used for producing large-sized pipes, but it is also suitable for pipes with smaller diameters and wall thicknesses than those made by the SAW process.

Common Uses

• Oil and Gas Transportation: Used in pipeline construction to transport oil, natural gas, and other fluids from production sources to refineries, terminals, and other distribution points.

• Energy and Industrial Infrastructure: Essential in developing and expanding energy and industrial infrastructure, including in the construction of pipelines for transporting water, heat, and other fluids required in various industrial processes.

Relevant Standards

• ISO 3183: Specifies the requirements for transportation pipelines and accessories used in the oil and natural gas industry.

• API 5L: Developed by the American Petroleum Institute, this standard sets the requirements for transportation pipelines and accessories used in the oil and gas industry.
