Introduzione alle prestazioni del prodotto
FRP (Fiber Reinforced Polymer) pipe is a high-performance composite pipe made from a combination of strong reinforcing fibers—typically glass, carbon, or aramid—embedded in a thermosetting resin matrix such as epoxy, vinyl ester, or polyester. This construction provides FRP pipes with excellent mechanical strength, corrosion resistance, and durability, making them ideal for use in demanding industrial and infrastructure applications.
One of the most significant advantages of FRP pipe is its superior corrosion resistance. Unlike steel or traditional metal pipes, FRP does not corrode when exposed to harsh chemicals, saltwater, or sewage. This makes it particularly suitable for use in chemical processing plants, desalination facilities, oil and gas pipelines, wastewater systems, and marine environments.
FRP pipes are also leggero, typically weighing only about 25–30% of steel pipes of the same diameter. This reduces transportation costs, eases handling, and simplifies installation. Despite being lightweight, they possess high tensile and compressive strength, allowing them to operate under high internal pressures and external loads.
Another benefit is the long service life of FRP pipes, which can exceed 50 years under normal operating conditions. They require little to no maintenance, contributing to a low lifecycle cost. FRP pipes also offer excellent thermal insulation and can be custom-fabricated in a wide range of diameters, thicknesses, and pressure ratings to meet specific project needs.
Common joining methods for FRP pipes include adhesive bonding, flanged joints, and mechanical couplings. The internal surface is often smooth, resulting in low friction losses and improved flow efficiency in fluid transport systems.
