FRP insulation pipe

Introduction:

FRP insulated pipes employ a foam-jacketed structure, primarily composed of FRP pipe, polyurethane, and an outer FRP protective layer. The superior advantages of the polyurethane jacket include cold resistance, heat insulation, lightweight, large bonding area with the outer protective layer, uniform load transfer, and good impact resistance.

Features:

Lightweight and high-strength, facilitating transportation, installation, and maintenance without the need for heavy lifting equipment.

The inner wall is resistant to scaling and remains smooth even after long-term use.

Low thermal conductivity, only 0.39 W/m·K, providing excellent insulation performance.

Good corrosion resistance and long service life, exceeding 30 years.

Specifications:

Operating Temperature: The long-term operating temperature of FRP pipes is generally -40℃ to 70℃. If a high-temperature resistant resin is selected, FRP pipes can operate continuously at 120℃ while maintaining good mechanical properties. Different resin systems (e.g., unsaturated polyester resin, vinyl ester resin, and epoxy resin) have different temperature limits. The appropriate resin should be selected based on the customer's application requirements.

Size: FRP pipes are available in sizes from DN25 to DN4000mm. Standard lengths for a single pipe are 6m, 9m, and 12m, but custom sizes are also available.

Pressure Rating: Pipes are designed according to pressure requirements, typically 0.25-16 bar.

Connection Methods: FRP pipes are primarily connected using socket joints, butt joints, flange joints, and sleeve joints.

Applications:

FRP insulated pipes can be used for transporting hot spring water, geothermal fluids in oil fields, and heating systems in cities and factories, among other applications requiring the transport of heat media.
