Abstract
Water leakage rate through packed gland was measured to determine how total packing height, packing compressive stress and fluid pressure affect the leakage rate in stugffing-box seals. Two types of packing rings, asbestos and graphite, were tested at room temperature. It was found that the leakage rate can be described by the theory of leakage through porous packing and/or clearance between packing and side walls. An experimental equation to describe the sealing capability of packing has been determined as a function of packing compressive stress and fluid pressure.
