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 is constructed of cast Nylon and is resistant to most common solvents, lubricants, hydrocarbons, esters, key tones and aqueous solutions of acids and alkalies at pH5 to pH 11. For more severe chemical service, PTFE lining is an option. Melting Point: 428°F/220°C. Elect. Resistivity: 1012 ohm/cm.
Other flange ratings or standards available on request.
