Selection and installation notes
- 304 or 316? General purpose; water, heating and cooling, compressed air and food plants. For chloride-containing media, sea water or swimming pools choose AISI 316.
- Seal threaded joints with PTFE tape or a stainless-compatible liquid sealant; over-tightening stainless threads can cause galling.
- Joining stainless steel directly to galvanized or carbon steel pipe can cause galvanic corrosion; a dielectric (insulating) union is recommended between different metals.
