HSAW PIPES

HSAW pipes are manufactured by forming hot-rolled steel coils into a helical shape and welding them with a submerged arc welding process. This construction method provides strong, high-quality welds, suitable for large-diameter pipes used in various applications.

Grades:

1. API 5L:
   • Grades X42, X46, X52, X56, X60, X65: Suitable for pipelines transporting oil, gas, and water.
2. ASTM A252:
   • Grades 1, 2, 3: Used for piling applications and structural support.
3. ISO 3183:
   • L245, L290, L360, L415: For natural gas and petroleum pipelines.

Sizes:

• Nominal Pipe Size (NPS): Typically ranges from 16 inches to 100 inches
• Wall Thickness: Varies depending on diameter and application requirements

Applications:

1. Oil and Gas Transmission: Ideal for long-distance pipelines due to their strength and ability to withstand high pressures.
2. Water Supply: Used in large-diameter water mains and distribution systems.
3. Structural Applications: Employed in piling, foundation work, and other structural support systems.

HSAW pipes are known for their ability to handle large diameters and high-pressure conditions, making them suitable for major infrastructure projects and industrial applications.
