Insulation Kits

Insulation kits are specified in order to offer electrical protection where two dissimilar flange materials are mated together.  The sets remove the possibility of the system acting as a galvanic cell and reduces the risk of corrosion of the pipe work.  They also offer cathodic protection by isolating protected piping systems and preventing the flow of electro-static charges.
