Chlorinated water disinfection introduces a corrosion consideration standard stainless doesn't always handle gracefully — material selection depends heavily on chlorine residual levels and water chemistry.
| Dominant Failure Mode | Chlorine-driven pitting, biofouling |
| Governing Standard | General ASME/TEMA, potable water certification where applicable |
| Typical Material Default | Stainless Steel 316L, Titanium for high-chlorine service |
| Typical Structural Type | Fixed or Floating, depending on fouling tendency |
Chlorine residual level is the key variable driving material selection.
There's no single universal threshold — it depends on residual chlorine concentration, temperature, and water chemistry together. High-chlorine disinfection applications often warrant titanium; confirm your specific conditions with our engineering team.
We can support potable water certification documentation needs; confirm your specific destination market's requirement (e.g., NSF-adjacent certification) at enquiry stage, since requirements vary by jurisdiction.
Generally less severe than seawater, but still relevant in water treatment, particularly in warmer climates or slower-flow sections of the system — flow design and material choice both play a role.
Every enquiry is checked against governing code, material compatibility and manufacturing feasibility before a quote is issued. Use our product, material, grade and standards guides to freeze the RFQ — then confirm with engineering.
Send your fluid service, pressure class and governing standard — we'll confirm the right product and material.
