Spiral SAW (SSAW) Steel Pipes

SSAW steel pipe is formed from coil with a spiral weld. For large-diameter projects in the Philippines, match the diameter and wall to the engineered pipe specification.

Applications

The final pipe must match the design, transported medium or structural duty, protection system, connections, inspection, and installation plan.

What is SSAW steel pipe?

Spiral submerged arc welded pipe is made by forming hot-rolled steel coil into a helix and welding the spiral seam. The process supports large-diameter pipe for transmission, piling, structural, and industrial projects.

The spiral seam identifies how SSAW pipe is made. Select the pipe against the project standard and grade, dimensions, pressure or structural design, protection, joints, testing and installation plan.

Compare SSAW and LSAW pipe against the project specification.

Specify the SSAW pipe your project needs.

Start with the project specification. Check how the pipe is made as well as its dimensions, grade, protection, joints and inspection requirements.

Standard and grade: Identify the governing standard, grade, mechanical properties, corrosion allowance, and required evidence.
Diameter and wall: State the OD, wall, length, quantity, tolerances, ends and design basis. For water transmission, include the pressure class.
Protection and installation: Coordinate coating or lining, joints, weld inspection, testing and installation. For piling and marine work, also review driveability and corrosion allowance.

Use the steel pipe standards guide alongside the project specification.

Check the SSAW diameter and wall together.

The spiral-welded range has its own diameter and wall combinations. Use the SSAW schedule when preparing the pipe requirement.

Outside diameter: 24 to 120 in
Wall thickness: 1/8 to 1 in

The overall ranges are reference limits, not a list of available combinations. A checked table of individual combinations is not yet available. Ask for a verified size schedule for your project.

Review SSAW sizes, properties, and grades.

Use these ranges to compare with the designer’s specification. Ask us to confirm the exact size and grade required; the tables do not show current stock or establish project suitability.

Review the SSAW pipe specification.

SSAW uses a spiral seam formed from coil. The project specification must determine whether the manufacturing route, grade, dimensions, coating, and testing are acceptable.
