The PGE insulation set

The PGE insulation set uses a machined, glass-reinforced epoxy (GRE) resin with an o-ring or spring energised seal. PGE can be used for flange ratings from class 150 to 600 and offers greatly improved compressive strength over conventional insulation sets with greater resistance to overcompression and cracking.

PGE can be constructed from standard G10 or high-temperature G11 resin with a seal ring which can be manufactured from a range of rubbers or PTFE. PGE insulation sets are supplied with GRE sleeves and washers with zinc plated steel backup washers.

PGE gaskets are supplied with GRE insulation washers with a greater compressive strength and resistance to cracking the commonly used materials.
