The structural s of fiberglass reinforced polyurethane insulated pipes are sequentially distributed from the inside out as anti-corrosion , anti-seepage , structural , protective , polyurethane insulation , and external protective . The physical and chemical properties of fiberglass reinforced polyurethane insulated pipes can be adjusted by changing the resin or reinforcing material to meet the needs of different media and working conditions.

Through the design of structural thickness and winding angle, the bearing capacity of the pipe body is adjusted, and fiberglass reinforced plastic pipes with different pressure levels or some special performance are made. This is incomparable to the l materials of fiber wound fiberglass reinforced polyurethane insulation pipes.

Compared to ordinary steel pipes and glass pipes, the strength and elastic modulus of steel pipes are larger than those of glass steel pipes. The linear expansion coefficient is basically the same, and the thermal conductivity and roughness are far greater than those of glass steel pipes.
