Insul-Flange Instulated Spool Flange

A cast-nylon insulating flange for use on marine docks and terminals.

If the piping system of a marine terminal is electrically conductive, an elecrical charge flows along the piping because of dock/pier-side cathodic protection systems. With the potential inductive effect of the piping system, a spark could occur at the moment when the hose is disconnected.

Insul-Flange controls undesirable electrical currents. The Insul-Flange prevents the heavy electrical flow in the piping system and eliminates the risk of an electrical arc when the hose is disconnected.

• Insul-Flange retains the properties of insulating flange gasket kits, but they are much easier to install and inspect for the properties of non-conductivity.
• Provides greater electrical resistance than regular insulating gasket kits.
• Prevents any possibility of an electric arc upon disconnection of the hose.
• Eliminates the need for separate bonding wire.
• Complies with several standards:
  • California State Lands Commission, M.F.D. § 2380
  • U.S.C.G. 154.810 Vapor Line Connections, Section G – Facility Vapor Connections
  • ISGOTT Chapter 6 – Electrical Insulation
