paronite of general purpose PON - B
Purpose General purpose paronite is used in the form of gaskets of various sizes and configurations for sealing flat connectors of fixed joints of the type: "smooth" with a working medium pressure of no more than 4 MPa; "Thorn - groove"; "Protrusion - depression" of vessels and apparatuses, pumps, fittings, pipelines, compressors, internal combustion engines and other units operating in various environments.
The permissible parameters for operation in various environments are as follows: Limit temperature Limit pressure Fresh superheated water 250 6.4 Saturated and superheated steam 450 6.4 Air - 50 + 450 1 Dry neutral and inert gases - 50 + 450 6.4 Liquid and gaseous ammonia - 40 + 150 2.5 Aqueous solutions of salts - 15 + 100 2.5 Alcohols 150 1.6 Heavy oil products (diesel oil, diesel fuel, fuel oil, paraffin, tar, asphalt, bitumen) 200 6.4 Light oil products (gas oil, gasoline , kerosene) 150 2.5 Liquid oxygen - 182 0.25 The roughness parameter of the sealed surfaces should be no more than 40 microns.
Technical characteristics General purpose paronite : is a sheet material made on paronite rolls from a mixture of chrysotile asbestos fibers, synthetic rubber, vulcanizing fillers.
Density, g / cm3 - 1.6 - 2
Conditional tensile strength, MPa, not less - 6.6
Weight gain in liquid media, % , no more than in water at a temperature of 100 ° C for 12 hours - 14 in kerosene at a temperature of 23 ° C for 12 hours - 40
Compressibility after relieving pressure 35 MPa, % , - 8 - 20
Recoverability after relieving pressure 35 MPa, % , not less - 30
All paronite batches are tested in special autoclaves for sealing capacity in a steam atmosphere at a pressure in the collector of 10 MPa and a temperature of 450 ° C and in a kerosene medium at a pressure in the collector of 15 MPa and a temperature of 20 ± 5 ° C.
Paronite is efficient in the Far North and tropical climate. For tropical climates, paronite is made using fungicides. Tropical paronite has the letter T. Paronite is produced both in the form of sheets and gaskets, the size and configuration of which are set by the customer's drawing agreed with the manufacturer.
