Fiberglass pipe square Tube FRP Pultrusion Profiles
FRP Tube which is one of its main products. The product is a kind of structural plates which uses high-strength fiberglass roving as reinforcing material, thermosetting resin as the base and then is cast and formed on a special metal mold.
1 FRP Pultrusion
Pultrusion is a continuous process for the manufacture of products having a constant cross section, such as rod stock, structural shapes, beams, channels, pipe, tubing, fishing rods, and golf club shafts. Pultrusion produces profiles with extremely high fiber loading, thus pultruded products have high structural properties.
Pultrusion is a manufacturing process for producing continuous lengths of FRP structural shapes. Raw materials include a liquid resin mixture (containing resin, fillers and specialized additives) and reinforcing fibers. The process involves pulling these raw materials (rather than pushing as is the case in extrusion) through a heated steel forming die using a continuous pulling device. The reinforcement materials are in continuous forms such as rolls of fiberglass mat or doffs of fiberglass roving. As the reinforcements are saturated with the resin mixture (“wet-out”) in the resin impregnator and pulled through the die, the gelation (or hardening) of the resin is initiated by the heat from the die and a rigid, cured profile is formed that corresponds to the shape of the die.
FRP tube can be used in electrical & electronics markets, chemical anti-corrosion markets , building construction markets , and foundation engineering markets .such as radome, insulation ladder,handrail, undergrand pression pipe, stairs,oversize bridge protection closed system, movable house structure, working platform, window frame, window sash and its components,freeway antiglare shield and its handrail, lamp post, water treatment, bracket for huge industry cooling tower, etc. It is an ideal loading frame on corrosion circumstances.
