Having been a fiberglass reinforced plastic (FRP) manufacturer and fabricator since 1965, Glas Mesh Company set as objectives (1) the development and marketing of several new and standardized FRP products for use by industry corrosion control engineers and technicians, and (2) insulating products suitable for the prevention of electrical contact shorts on buried and exposed pipelines or mains. Until recently, companies simply used whatever they happened to have on the job site. After a comprehensive development program, Glas Mesh Company designed and began fabricating a line of corrosion and abrasion control products specifically shaped for piping and particularly useful to the gas, oil and chemical industries. These new FRP products are standardized, work effectively and are economical to use. They are also immediately available from stock.
The first of Glas Mesh Company's line of FRP products was the highly successful Roll-On Shield, which stops corrosive and electrolytic wear of ferrous metal suspended or overhead pipe mains effectively and economically. FRP Roll-On Shields also eliminate or materially reduce hot or cold energy loss on thermally insulated pipe mains and serve to control abrasion and wear on plastic piping systems. Roll-On Shields are pre-shaped 240o peripherally.
Today Glas Mesh Company provides a complete line of FRP corrosion and abrasion control products: FRP Insulation Spacers, FRP Roll-On Shields, FRP Pipe Saddles, FRP Casing Insulators, and FRP Flatties. All are pre-formed and fabricated for specific functional uses.
When considering the advantages of modern plastics (light weight , ease of handling and installation, high dielectric strength, no corrosion problems), and their disadvantages (cold flow, cold temperature embrittlement, heat distortion, low abrasion resistance, relatively low compressive strength), it becomes obvious that fiberglass reinforced plastic (FRP) provides all the physical advantages and properties while eliminating or materially reducing the disadvantages of the non-reinforced plastics.
FRP's properties of light weight, ease of handling and installing, high dielectric strength, corrosion resistance with great compressive strength combine to make it the state-of-the-art material for Glas Mesh FRP abrasion control and electrical insulation products. Glas Mesh FRP products will not cold flow under pressure nor become brittle in cold temperatures, will not soften nor distort from heat, and they have excellent abrasion resistant properties.
Glas Mesh products are fabricated from a precision manufactured, filament wound, ultraviolet protected, FRP epoxy with integral epoxy liner and exterior coating. FRP products' inside diameters approximated the outside diameters of the carrier pipes, thus assuring close fit and requiring minimum clearance during installation. Glas Mesh products meet all known industry recommended standard specifications and properties.
Application: Provides an extremely tough, inexpensive casing insulator that electrically isolates a gas carrier main from a steel casing, and provides excellent abrasion control. The two pieces snap together surrounding the carrier pipe and separating it from the casing. No tools, banding or welding are required. Ideal for retrofits where original or existing spacer or insulator has been damaged, deteriorated or failed. Special lengths can be made available.
