  • Description

The filament winding and material parameters of epoxy fiberglass tubes result in a high elastic modulus typically ranging between 2.5-3 GPa (363-435 ksi). This characteristic provides excellent stiffness and stability, making it suitable for use in challenging environments in fields such as chemical engineering, water treatment, marine engineering, etc. Additionally, its outstanding corrosion resistance is also one of the critical reasons why this product is highly favored.
