Anti corrosion Reinforced fiberglass frp pultrusion square pipe

Overview

FRP square pipe has high mechanical strength, strong chemical resistance, excellent fire and flame resistance, low thermal conductivity, small expansion coefficient, good temperature resistance, light weight, excellent anti-aging performance, long service life, easy installation, and Strong design, widely used in food, chemical, electric power, pharmaceutical, pesticide, dye, steel, smelting, water treatment, tap water, marine aquaculture, desulfurization and environmental protection.

The FRP square pipe is one of many sizes of pultruded FRP profiles, with uniform internal and external colors, and the color can be selected at will. Color can be customized according to customer requirements to improve the environment of the production site. Its designability is strong and it can design different sizes of FRP square tubes according to actual needs. Its flexible and convenient design makes it widely used in many fields.

(1) High strength:

The tensile strength of the glass fiber reinforced plastic square tube is 150-300MPa, the bending strength is 200-300MPa, and the bending strength retention rate after 1000h artificial accelerated aging can reach 78%.

(2) Low deformation rate:

The length change of FRP pultruded profile after 1000h artificial accelerated aging is +0.03%, and the width change rate is -0.07%. Therefore, the geometric shape and size of products made with the pultruded profile can be kept stable for a long time.

(3) High heat distortion temperature of glass fiber reinforced plastic square pipe:

 The heat distortion temperature of pultruded profile is 186℃, which will not soften at high temperature, and will not be brittle at -60℃, ensuring normal use under various environmental temperatures.

(4) Low water absorption:

the water absorption of ordinary glass fiber reinforced plastic products is less than 0.5%, while the water absorption of pultruded profiles is only 0.257%, which is suitable for use in humid environments.

(5) Low thermal insulation coefficient:

The heat transfer coefficient of the pultruded profile is close to that of rigid PVC, and the thermal insulation coefficient of the single-frame double-glass insulation window made of it is only 2.69W/(m2K), while steel , The thermal insulation coefficient of the same type windows made of aluminum is as high as 4.0W/(m2K), indicating that the energy saving of FRP doors and windows is very obvious.

(6) Strong corrosion resistance:

The hardness retention rate of pultruded profiles is 95% after immersed in 3% HCI aqueous solution for 24 hours. After soaking in 3% NaCl aqueous solution for 24 hours, the hardness retention rate is 89%. Therefore, doors and windows made of glass fiber reinforced plastic pultruded profiles are not only suitable for ordinary houses, hotels, restaurants, but also for industrial plants in coastal areas and corrosive working environments.

(7) Adapt to environmental requirements:

The production process used in processing pultruded profiles has the characteristics of low noise, high efficiency, low power consumption, and low pollution, which meets the relevant national environmental requirements.
