Beldam Pilotgraph 4000

Beldam Pilotgraph 4000 is a 'Crossplait' constructed packing. Manufactured from innocent re-inforced pure expanded graphite. Also contains corrosion inhibitors which enables the packing to be used in contact with Stainless Steel. high thermal conductivity, self lubrication and rapid heat dissipation are just three of the advantages of using Beldam Pilotgraph 4000.


Petrochemicals, refineries, power stations, steel works (any steam valves).

Chemical Compatibilities

For the pH range 0-14, the packing is chemically inert and suitable for steam. It should not be installed in strong oxidising environments such as hot concentrated nitric acid, highly concentrated sulphuric acid and molten alkali metals.

Sizes Available

All square sections from 3mm (1/8”) to 25mm (1”) are generally available from stock in differing lengths depending on the cross section. Larger and rectangular sections can also be manufactured to order. Pilotgraph 4000 and 4003 packing can also be supplied in preformed or die formed rings.
