Joint packing is a deformable material which must prevent or control fluid passing between surfaces in relative movement, one towards the other. Working scheme of a pump stuffing box Working scheme of a valve stuffing box TECHNICAL ASPECTS End use Rotating and alternatives pumps, in general turning machines Valves and taps Raw materials used Para-aramid Para-aramid / viscose Preox Carbone Carbone / Inconel Fibres choice To make these braids, Schappe offers a wide range of dry or coated yarns, depending on the conditions of utilization. Generally, the choice of components will result from the following requirements : Mechanical resistance Temperature resistance Thermal conductivity Lowest friction coefficient Chemical inertia Lowest dilation coefficient ADVANTAGES The fibrous structure of Schappe spun yarns is perfectly suited for these type of applications for several reasons : The ability for coating the braid is improved. Water-proofing is then better and the friction between the braid and the shaft is decreased. The elastic behaviour of the braid is increased which contributes to ensure a better packing. The possibility to mix different types of fibres. Schappe Techniques • Z.A.
