Area of usage: used for packing armature, tubing and other equipment of energy engineering, chemical and petrochemical industries.
Liability and impermeability. Pressed sealing rings of pure expanded graphite are universally recognized and popular decision when packing stuffing boxes of armature at heat power stations, plants etc. Thanks to its perfect sealing qualities these rings ensure high grade of reliability and resource of packing assembly at area pressure of up to 40 MPa.
High working temperatures. These rings almost do not lose its weight and volume with time at temperature of 650C, especially in confined space of gland chamber.
Properties’ stability. These rings keep its properties at temperatures from -200C to +3000C during all period of exploitation. High resiliencies do not getting lower with time and allow to keep impermeability at many time heat changes without additional service.
High chemical resistance. These rings are universal as they possess high chemical resistance to nearly all areas excluding strong oxidants.
Absence of corrosion. Thanks to chemical inactivity these rings cause insignificant electrochemical corrosion of packing surfaces and so prolonging equipment exploitation period. And adding of inhibitors almost makes corrosion impossible.
Different types of structures. Types and manufacturing methods of different ring structures and the sizes also are defined according to Management directive “Gland Packings of Expanded Graphite for fittings and tubing(up to 40 MPa and 600C) that was developed by JSC “IrkytskNIIChimMash
