ISOMAX LPS FLANGE INSULATION SET

ISOMAX HPS FLANGE INSULATION SET

ISOMAX LPS Flange Insulation Set

The LPS gasket is an economical seal for electrical flange isolation and general applications requiring higher performance capabilities than those offered by neoprene-faced phenolic gaskets.

The gasket comprises grooves that are machined into high strength G10 laminate and in to which are inserted either spring energized PTFE or Viton o-ring seals which offer excellent sealability at low loads. The LPS gasket is highly suited for use in classes up to and including class 600 lb gasket.

The LPS gasket is available in full face (Type E) and ring style (Type F) configuration.

General Properties
• Gives a high sealing reliability in low pressure system.
• Excellent electrical insulation when used on cathodic protection systems.
• Is suitable for most hydrocarbons services subject to seal ring material selection.
• Reduces galvanic corrosion in dissimilar metal flanges.
• Design eliminates media-induced corrosion and flow-induced erosion from flange faces.
• Design requires reduced flange/bolt assembly stress.
• Easy installation and removal.
• Suitable for all ANSI rated flanges up to class 600 lb.

Materials
Gasket Insulating Material & Washers: G-10 Glass Reinforced Epoxy (GRE) as standard (G-11 high temperature grade also available).
Spring energized PTFE or O-Ring pressure activated seal: PTFE (spring energized) as standard (Viton and Nitrile also available).
Insulation sleeves: GRE (standard) or Nomex for high temperature service.

LPS Flange Gasket Advantages & Benefits

  • Low pressure sealing (ANSI class 150, 300 and 600) service.
  • Seals are pressure activated.
  • High strength laminate material reduces failure due to excess compression.
  • Excellent electrical insulation when used on cathodic protection systems.
  • Design eliminates media-induced corrosion and flow-induced erosion from flange faces.
  • Reduces galvanic corrosion in dissimilar metal flanges.
  • Also available with a variety of elastomeric seals.
  • Easy installation, assembly and removal as design requires reduced flange/bolt assembly stress.
  • Flanges do not have to be spread as would be the case with RTJ gaskets. The LPS easily slips in place.
  • Gasket is self-aligning and centering, quick to install, no special tools are required.
    Maintenance-free, corrosion resistant design.
