Slade Incorporated has become a globally recognized company with all manufacturing performed at our facility located in Statesville, North Carolina USA. Founder Bob Crosier started Slade by drawing on his lifetime of experience in the sealing industry. Originally, Slade was to become a yarn manufacturer, supplying the packing industry with the first braidable expanded graphite yarn. Slade patented this newly developed technology in both its design and the machinery used to produce the graphite yarns.
In the years following, Slade not only produced that braidable expanded graphite yarn but also became a braided graphite packing manufacturer as well, the first of its kind. Slade has taken the raw materials of expanded graphite and high tensile strength carbon to form the finished product of a flexible, rope-style valve and pump graphite packing capable of high temperature and high pressure without the use of lubricating type binders.
Canusa-CPS is a forerunner in developing and manufacturing of specialty pipeline coating products and systems to protect against corrosion of pipeline joints.
Slade manufactures all of its own patented graphite yarns. The advantage is that each individual strand has its own unique core made of high tensile carbon fiber. Our yarns are protected by US & EU patents, and were developed to conduct heat like steel alloys, to transfer the heat away from the shaft.
When Slade Foil is compressed by 25% (the denser the better), die-formed density is achieved in the stuffing box. This forms a “heat sink” in the stuffing box, eliminating the need for flush-water to cool the shaft sleeve in most applications. In addition, Slade reduces the number of oxidation sites in the packing yarns so that Packing can be used in more severe temperature and chemical applications than competitor’s packings.
