2023 Manufacturers supply FRP Fiberglass Pipes Price,frp round tube

FRP tubing/frp circular tube/hollow circular tube

FRP pipe is made of unsaturated polyester resin, continuous glass fiber yarn and glass fiber mat, the pultrusion process control, the process is irreversible, it can't be melt or forming again again, so it has high strength, light weight, antiseptic, beautiful, impact resistance and other characteristics

Molding process
During the pultrusion process, the raw material are pulled through a heated steel forming die using a continuous pulling device when the reinforcements are saturated with the resin mixture in the resin bath and the wetted reinforcement package is wrapped in a surfacing veil. the completed package then goes into premolding stage that roughly forms the package into the appropriate shape to enter the heated trimming die for curing. the trimming die is the exact shape of the final part desired. upon exiting the trimming die, the part is over 90% processing and solid. Cutting in accordance with requirements of the length, the entire process is completed.

Product specification

Company can also customize product according to customer requirements, such as perforation sizes, different shapes, different sizes, different load requirements, maximize meet customer demand, and reduce losses to a minimum, cost savings for customers.

Product advantage

(1) high strength Pultrusion profiles is 150-300 mpa tensile strength, bending strength of 200-300 mpa, the 1000 h after artificial accelerated aging of bending strength retention rate can reach 78%.
(2) low deformation rate Glass fiber reinforced plastic pipe by 1000 h after artificial accelerated aging change in length is + 0.03%, the width of the rate of 0.07%. Therefore making products with the pultrusion profiles geometric shapes and sizes can keep the long-term stability.
(3) high thermal deformation temperature Pultrusion profiles of the thermal deformation temperature of 186 ℃, high temperature softening, 60 ℃ the same crisp, to ensure the normal use of various kinds of ambient temperature.
(4) the bibulous rate is low General purpose bibulous rate is less than 0.5%, and the bibulous rate of pultrusion profiles is only 0.257%, suitable for use in damp environment.
(5) low coefficient of heat preservation and heat insulation heat transfer coefficient of pultrusion profiles with hard PVC close, made of the single frame of the double glass window insulation thermal insulation coefficient of only 2.69 W/(m2K), and with the same type of steel, aluminum ingot the coefficient of heat preservation and heat insulation of the window is as high as 4.0 W/(m2K), shows that FRP doors and Windows of energy saving is obvious.

widely used in petroleum, chemical industry and other corrosion environment of stairs and railings, operating platform, corridor, bracket, etc
