Graphite flange gaskets PFG (ПФГ)

Low prices. Quality. Optimal delivery times. New generation seals. Tightness 100% throughout the entire service life. Wide working range: the whole range of working environments, including aggressive ones; temperature from -200 to +800 C; pressure up to 25 MPa (250 kgf/cm2).

Flanged graphite gaskets PFG from reinforced (not reinforced) graphite sheet
Use
PFG are designed for sealing critical flange joints of the "plane-plane", "protrusion-depression", "spike-groove" type of pipelines, fittings, pumps, vessels, apparatus and various technological equipment.

Area of application
In all industries, from mining, processing and ending with the nuclear industry.

PFG manufacturing method
PFG is made by cutting and / or cutting out of sheet thermally expanded graphite TRG (graphite paper) without the use of abrasive tools.

PFG design
1. Not reinforced.
2. Reinforced (stainless steel, carbon steel, etc)
3. Without obturator (protective ring)
4. With obturator (stainless steel):
– on the outer diameter;
– on the inner diameter;
– on the outer and inner diameters

Properties
1. High tightness
2. Chemical resistance (inertness to various aggressive environment)
3. Heat resistance
4. Radiation resistance
5. Elasticity (in compression) - reusable.
6. Not susceptible to aging
7. Environmental safety - no harmful radiation, vapors, pollution

Operating conditions
1. Temperature: from -200 to +800 C
2. Pressure: up to 25 MPa (250 atm)

Working environment
1. Air at temperatures from -200 to +800 C.
2. Oxygen -  from -180 to +350
3. Carbon dioxide - up to +600
4. Water steam - up to +600
5. Fuel (jet, diesel, kerosene, gasoline) - from freezing point to flash point
6. Mineral and synthetic oils - from freezing point to flash point
7. Oil and petroleum products
8. Natural and associated gases (including liquefied gases)
9. Fuel conversion products (gaseous, liquid, solid)
10. Aggressive and other substances

Standard sizes
