Garlock® Braided Compression Packing Construction

Yarns, rovings, ribbons and other various materials, either alone or in combination, are processed on equipment where strands pass over and under strands running in the same direction. Resulting packings are usually supplied in square cross-se ction, but rectangular sizes can also be braided by this method. The packing is usually and can carry a large percentage of lubricant. Square braided packings are easy on equipment and are generally used for high-speed rotary service at relatively low pre ssure. The packing's softness makes it usable on old or worn equipment.

Yarns, rovings, ribbons, and other forms of various materials, either alone or in combination, are processed on equipment where strands criss-cross from the surface diagonally through the body of the packing. Each strand is strongly locked by other strands to form a solid integral structure that cannot easily ravel or come apart during service. There are no jackets to wear through, and no plates to come loose. Lattice Braid packing has more even distribution of yarn density throughout and has the potential for improved lubricant retention. The finished packing is relatively dense, but flexible. Lattice braid packings are suitable for applications on reciprocating and centrifugal pumps, agitators, valves, and expansion joints and in grooves.

Also known as round braid or multiple braid. Round braiding machines braid tubular jackets using yarns, rovings, ribbons and other forms of various materials, either alone or in combination. Size is obtained by braiding jackets on over the oth er (braid-over-braid). Finished packings can be supplied in round, square or rectangular cross section. Braid-over-braid packings are relatively dense and are recommended for high pressure, slow-speed applications such as valve stems, expansion joints, gr oove gasketing etc.

Finished product is produced by round braiding one or more jackets of yarns, rovings, ribbons or other forms of various materials over a core, which may be extruded, twisted wrapped or knitted. This construction allows for a wide range of dens ities and cross sectional shapes
