DESCRIPTION

Corrosion Resistance IntegraLine fiberglass pipe ( fiberglass reinforced plastic pip – FRP) is designed to be “user friendly.” The resin, glass reinforcement materials and composite construction were selected to provide consistent corrosion resistance for the majority of chemical applications for which FRP pipe is considered appropriate. There remain certain extreme chemical services for which special construction and alternative resins should be considered. Fibrex can advise if this is required for your application. Weather Resistance IntegraLine pipe utilizes a heavily resinated exterior coat containing an ultraviolet stabilizer to impart long term resistance to the effects of sunlight and other weathering elements. Should pipe become weathered after many years in particularly severe environments, the exterior can be sanded and resin coated or painted. Color Pigmented exterior gel coats are not used on IntegraLine pipe in order to take advantage of the natural translucency of FRP. Visual inspection of the pipe, both new and after years of service, is more reliable with a “natural” laminate. Additionally, the liquid contents can often be observed in the pipeline… sometimes a process control advantage. When special color coding is required, however, this can be provided at a nominal added cost and slightly longer delivery time. Durability fiberglass_pipe_frp_shopThe high tensile elongation properties of the vinyl ester resins utilized in IntegraLine pipe impart a superior toughness to the pipe enabling it to resist cracking and crazing of the resin when subjected to heavy design loads. In addition to high fatigue resistance, this toughness also provides a safety factor against impact damage during shipping and installation. Resin IntegraLine pipe is manufactured with a premium vinyl ester resin as the standard production resin. Other vinyl ester resins specified by the customer are available, however delivery lead times will generally be longer. Epoxy vinyl ester resins are premium corrosion resistant resins. At both room and elevated temperatures, these resins offer resistance to a broad range of acids, alkalis, bleaches and solvents making them the appropriate choice of resins in many chemical processing industry applications. These resins, when properly formulated and cured, comply with FDA regulation 21 CFR 177.2420 covering materials intended for repeated use in contact with food. Specific chemical resistance information can be found in the Chemical Resistance and Engineering Guides, available from FIBREX or directly from the resin manufacturers. Reinforcement Materials A “C” glass (chemical grade) veil is provided on all surfaces exposed to corrosive media. Fiberglass used in all subsequent layers of the laminate has excellent electrical resistivity, high tensile strength, moderate thermal conductivity and is noncombustible. The basic types of fiberglass materials used; mat, woven roving and continuous strand, are selected for their physical properties, manufacturing characteristics and the chemical resistance of the laminate resulting from their use. Corrosion Barrier The corrosion barrier of IntegraLine pipe is nominally 100 mils thick and is comprised of 70% to 80% resin. This highly resinated laminate is reinforced by one layer of “C” glass veil followed by two layers of randomly oriented fiber strand mat. Structural Laminate Straight Pipe IntegraLine pipe is manufactured by the filament winding process utilizing continuous fiberglass strand wound in a helical pattern at a nominal 55 degree wind angle to produce an optimum combination of hoop and axial properties for most typical applications. The high glass content resulting from the filament winding process imparts excellent strength characteristics to the laminate providing superior protective structural backup to the resin rich corrosion barrier. Fittings IntegraLine pipe fittings are manufactured utilizing a highly efficient contact-molded laminate consisting of alternating layers of glass fiber strand mat and bi-directional woven glass roving. The high glass content resulting from the specific laminating process used for IntegraLine pipe fittings permits the wall thickness of this hand-layup process to closely approximate the wall thickness of filament wound straight pipe in equivalent pressure rated classes.
