Spiral Submerged Arc Welded

Spiral Submerged Arc Welded

SSAW (Spiral Submerged Arc Welded) Steel Pipes are manufactured using a spiral welding process where a steel coil is continuously formed and welded. Designed for large-diameter and long-distance applications, SSAW pipes are available in outside diameters ranging from 219.1mm to 3500mm, wall thicknesses from 6mm to 25mm, and lengths of 3 to 18 meters. Known for their cost-effectiveness and strength, these pipes are ideal for water transport, oil & gas pipelines, piling, and civil infrastructure.

Manufacturing & Surface Treatment:

Produced using the automatic double-wire double-sided submerged arc welding process, SSAW pipes offer excellent compressive and impact strength, ensuring high safety and long service life. Surface treatment options include bare, light oiling, black painting, and anti-corrosion coatings like FBE, 2PE, and 3PE, providing protection against harsh environmental conditions. Pipes are packaged in bulk with end protectors and waterproof wrapping to prevent damage during transit.

Standards and Steel Grades:

SSAW pipes are manufactured according to major standards such as API 5L, ASTM A53, ASTM A252, EN 10219, EN 10248, EN 10249, and AS 1163. Steel grades include X52, X60, X65, X70, X80 for oil and gas applications, and S275GP to S430GP for structural and piling use. These standards ensure consistent quality, mechanical properties, and performance across industries worldwide.

Applications and Versatility:

Thanks to their large diameter and high-pressure handling capabilities, SSAW pipes are widely used in water supply systems, oil and gas pipelines, steel piling, port construction, marine structures, and offshore foundations. They are particularly suited for applications requiring foundation stability, such as bridge piles, dock piles, and harbor engineering, where durability and strength are critical under load and environmental stress.

Advantages and Performance:

SSAW steel pipes offer excellent weld quality, uniform thickness, and cost efficiency, especially for long-distance pipeline projects. Their spiral design allows for greater diameter flexibility, making them ideal for transporting large volumes of fluid or serving as load-bearing structures. With high impact strength and pressure tolerance, they deliver long-term reliability and reduced maintenance in both land and marine environments.
