Gaskets and rings:

Gaskets are designed to lock and seal flanges where heat, pressure, vibration and flow rates are beyond the capacity of conventional materials.
They are used worldwide for pipelines and pressure vessels on steam, petrochemical, nuclear, marine and hydraulic plant, as well as on heat exchangers.

Insulation Sets:

Insulation kits are used in petrochemical applications.
Insulation sets are primarily used in petrochemical applications to electrically isolate two mating flanges.
Insulation sets are also employed to prevent the flow of electrostatic charges and to reduce sparking in hazardous environments.
