On the side pressure in a Ftoroplast-4 (Teflon) packing

Deformation Characteristics of Gland Packings Made of Heat-Expanded Graphite

“…In [1-3], the coefficient k was determined from the peripheral deformation of the outer surface of the chamber wall at a fixed axial load on the packing placed in the chamber. This deformation can be determined from the readings of the strain resistors attached to the wall [1] or of an elastic element in contact with the outer surface of the chamber wall [2,3]. The accuracy of k determination depends on the radial rigidity of the chamber wall (on the wall thickness): the greater the rigidity, more reliable the results.…”
