Marine Generator Exhaust Flex Pipes:
- Size: 2" to 24" diameter (custom sizes available)
- Grade: ASTM A240/A312 (stainless steel), ASTM B111/B543 (copper-nickel)
- Viscosity: N/A (not applicable for solid piping)
- Buoyancy: Typically negative (depends on material and insulation)
- Material: 304/316L stainless steel, Cu-Ni 90/10 or 70/30, EPDM rubber (flexible sections)
Marine Exhaust Systems:
- Size: 3" to 36" diameter (varies by engine output)
- Grade: ASTM A53/A106 (carbon steel), ASTM A312 (stainless steel)
- Viscosity: N/A (system design accounts for exhaust flow resistance)
- Buoyancy: Neutral/positive (insulated systems may include floatation)
- Material: Carbon steel, 316L stainless steel, fiberglass-reinforced elastomers
Common Features:
- Temperature range: -20°C to +700°C (depends on insulation)
- Pressure rating: 10-150 PSI (flex pipes lower than rigid systems)
- Corrosion resistance: Saltwater-rated coatings or alloys
- Flexibility: Multi-ply bellows (stainless steel) or reinforced rubber
