AESSEAL® offers a selected range of gland packing that have been specifically designed and manufactured to reduce plant operational and maintenance costs. Therefore, it is of the utmost importance to select the highest quality modern fibre packing in an inter-braided construction and optimized profile to provide the most resilient, long-lasting packing sealing solution.
Maximum Service Life and Resilience
The braiding quality is of prime importance, otherwise it could significantly affect the service life. Packing manufactured using smaller or obsolete braiding machines lacks the strength of real crosslock construction, because they are more rounded in cross-section and not as dense.
If the packing braid is loose, it is less durable. If round, it requires a greater gland pressure to carry out the sealing process thereby causing higher mechanical stress. As the packing wears out, more and more adjustments are needed to the gland, which in turn causes further mechanical stress on the packing, resulting in reduced life span.
The highest level of packing design is to be found in a trapezoid shaped construction as described on pages 9-11 of this publication.
