When packing the stuffing box on a valve whether during
manufacture or routine maintenance, ease and speed of fitting the
packing is of important consideration.
To facilitate this Hindustan Composites Ltd. offers preformed
rings intended for use to contain various media at different
temperature and pressure ranges.
The packings are available in scarf joined or angular slit open
blocked ring forms made to finely controlled.
densities and dimensional tolerance. The rings are available in
square as well as rectangular cross section. Selection of
appropriate metal in the wire form, binder and lubricant is an
important criteria depending upon the application.
Use of packing in ring form facilitates easier and quicker fitting
-an all important consideration in today's escalating labour and
overhead costs.
Since the rings are pre-compressed they fit and seal the shaft and
the entire gland chamber uniformly along the complete length thus
eliminating localized shaft wear producing a longer lasting seal.
