FRP PIPE
Fiberglass pipes are lightweight and economical pipes that can replace steel, iron, and concrete pipes.The core advantages of FRP continuously wound pipe lie in its high strength, high rigidity, excellent corrosion resistance, superior hydraulic performance, superior leak resistance, and the economic and length advantages afforded by continuous production. It seamlessly integrates materials science with advanced manufacturing processes, offering a high-performance, cost-effective, and environmentally friendly modern engineering piping solution, particularly suited for long-distance, high-flow, and corrosive transport.
Epoxy fiberglass pressure pipes typically refer to composite pipes made of epoxy resin as the matrix and glass fiber as the reinforcing material, manufactured through processes such as winding, and are specifically designed to withstand internal pressure.
Products Description
Epoxy fiberglass pressure pipes typically refer to composite pipes made of epoxy resin as the matrix and glass fiber as the reinforcing material, manufactured through processes such as winding, and are specifically designed to withstand internal pressure.
Good Pressure Resistance
Through scientific winding design, the circumferential and axial strength of the pipe can be precisely controlled to meet the requirements of different pressure levels. The working pressure can typically range from a few kilograms to tens of kilograms.
Main Application Areas
Petrochemical industry : oilfield water injection pipes, crude oil transportation pipes, chemical process pipelines, and transportation of corrosive media.
Municipal water supply and drainage : main urban water supply pipelines, reclaimed water pipelines, and pressurized sewage pipelines.
Power industry : circulating cooling water pipelines, ash and slag conveying pipelines, and desulfurization system slurry pipelines.
Marine engineering : seawater desalination plant pipelines, ship pipelines, and offshore platform water supply pipelines.
Mining : Slurry transport pipelines, tailings transport pipelines, ventilation pipelines.
Food and brewing : Due to its smooth inner wall that does not accumulate scale, it is also used in process pipelines in the food and beer industries.
Specifications and Standards
Diameter range : typically from DN25 to DN4000 or even larger.
Pressure ratings : Common ratings include PN0.6, PN1.0, PN1.6, PN2.5, and PN4.0 MPa, and higher pressure ratings can also be customized.
Implementation standards : Chinese standards: GB/T 21238 "Glass fiber reinforced plastic sand-filled pipe", JC/T 695 "Centrifugally cast glass fiber reinforced unsaturated polyester resin sand-filled pipe", etc. (Note: These standards are mainly for polyester pipes, but epoxy pipes can refer to their mechanical performance requirements, and corrosion resistance needs to be agreed separately.)
International/Foreign Standards: ASTM D2996 (centrifugal casting), ASTM D2997 (fiber winding), AWWA C950, etc.
Comparison with Other Types of Fiberglass Pipes
| characteristic | Epoxy fiberglass pressure pipe | Unsaturated polyester (UP) fiberglass pipe | Vinyl ester (VE) fiberglass pipe |
| Corrosion resistance | Excellent , especially for alkaline and organic solvents. | Good, but slightly worse for alkaline media and some solvents. | Excellent overall corrosion resistance, especially resistant to strong acids and high-temperature corrosion. |
| Temperature resistance | Medium (approximately 80-110°C) | Lower (approximately 60-80°C) | High (approximately 100-120°C) |
| Mechanical strength | High, strong adhesion | good | Very high, extremely strong adhesion |
| cost | higher | lowest | Highest |
| Main applications | Chemical industry, high-requirement water supply, power | Municipal water supply and drainage, cooling water, and general corrosive environments | Stringent chemical and metallurgical |
Epoxy resin pipes are an upgrade from unsaturated polyester pipes in terms of corrosion resistance, mechanical strength, and overall performance , but they are also more expensive. For the most demanding corrosive environments, vinyl ester pipes, which offer better performance but are also more expensive, are chosen.
