Expanded Graphite

Expanded Graphite PA2000-Exponded Grophite Packint Braided from low-sulphur expanded graphite yarns,which are reinforced by cotton fiher.It has a very low friction,does mot damage shafts or stems.Itshows good thermal and chemical resistance and high elasticity.Other reinforcement materials are also available: Glass fiber---High strengrh,lower cost Garbon fiber--Less weight loss 200k--Graphife panking with Corrosion inhibifor Corrosion inhibitor acts as a sacrificial anode to protect the valves stem and the stuffing box. Application:Usedin valves,pumps,expansion joints,mixers and agitators in high-pressure,high-temperature hostile environments of hydrocaron processing,pulp and paper,power stations,refineries and industries where effective sealing is vital.
