Overview of AS 1579 Spiral Welded Pipe
AS 1579 Spiral Welded Pipe is a widely used steel pipe standard in Australia and New Zealand, primarily designed for water transmission, wastewater treatment, and industrial applications. Governed by Australian Standard AS 1579, this specification ensures high strength, corrosion resistance, and durability, making it an ideal choice for municipal water projects, irrigation systems, and large-scale infrastructure.
Unlike seamless or ERW pipes, spiral welded pipes offer cost-effectiveness, large-diameter capabilities, and superior pressure handling, making them a preferred option for long-distance water supply systems.
