Product Description
Product Overview

This Water Treatment 304 Seamless Stainless Steel Pipe is produced for municipal water supply, drinking water distribution and wastewater treatment plants where reliable, hygienic and long-lasting piping is required. The 304 austenitic grade resists rust and general corrosion in fresh water, so the pipe keeps the water clean and avoids the discolouration and leaks that affect ordinary carbon steel or galvanised pipe over time.

Because it is seamless, the pipe has no internal weld bead that could trap deposits or reduce flow, making it a practical choice for pumps, filtration skids and distribution manifolds.

The pipe is supplied in outside diameters from 6 mm to 630 mm and wall thickness from 0.5 mm to 30 mm, pickled and annealed for a clean internal and external surface. Smooth bore, precise dimensions and full traceability help water utilities and contractors meet project specifications. Lengths of 6 m or 12 m are standard, and cut-to-length supply keeps site waste to a minimum on large distribution projects.
