ASTM A252 GR.3 LSAW PIPES

Sizes：

Outer Diameter：Ranges from 406 mm to 1420 mm

Wall Thickness：Typically between 8 mm to 60 mm

Length：Ranges from 1m to 18m,depending on the application

Applications:

- Foundation Piling: For buildings, bridges, and other heavy structures.

- Marine Structures: Such as offshore platforms, docks, and seawalls.

- Low-Pressure Fluid Transport: For water, gas, and oil in non-critical environments.

Advantages:

- High Strength: Suitable for heavy-load applications.

- Excellent Weldability: Ensures strong and durable joints.

- Corrosion Resistance: Can be further enhanced with coatings or treatments.

- Versatility: Available in various sizes and thicknesses to meet diverse project needs.

Welding performance: ASTM A252 GR.3 steel pipes usually adopt double-sided submerged arc welding technology to ensure that the welding quality is stable, and it is not prone to defects such as misaligned edges and unwelded.

Production process:

- Steel plate pretreatment: Ensure that the surface of the steel plate is not scratched, uniformly deformed, and residual stress is reduced.

- Welding technology: Adopt advanced submerged arc welding technology to ensure that the welding position is accurate and the quality is controllable.

- Inspection and quality control: Ensure that products meet standard requirements through hydraulic testing, eddy current testing and third-party testing.
