Innovation that Drives Performance, Efficiency and Long-Term Value
At Dongjie, innovation is not a slogan—it is a systematic approach built on research collaboration, engineering tools, advanced materials, and rigorous performance validation.
This is a composite pipeline made with glass fiber as the reinforcing material and resin as the matrix, and it is formed through the winding process.
Core feature
• Corrosion-resistant: Resistant to acids and alkalis, to chemical media, does not rust or form scale, suitable for harsh working conditions.
• Lightweight and high strength: The weight is only 1/4 to 1/5 of that of steel pipes, with high strength and strong pressure-bearing capacity.
• Low fluid resistance: The inner wall is smooth, resulting in high conveying efficiency and low energy consumption.
• Long lifespan: Anti-aging, anti-fatigue. The designed service life can reach 50 years.
• Insulation and flame retardancy: Non-conductive, flame retardant performance, suitable for power and chemical industries scenarios
This is a fiberglass-reinforced plastic panel formed by the pultrusion process, and it is a lightweight and high-strength composite sheet.
Core feature
• Corrosion-resistant: Resistant to acids and alkalis, anti-aging, suitable for humid and corrosive environments
• Lightweight and high-strength: Light in weight, high in strength, and in load-bearing performance.
• Insulation and flame retardancy: Non-conductive, flame-retardant, suitable for power and chemical industry scenarios
• Structural stability: Wave/rib design, with strong resistance to bending and impact.
• Easy to install: Can be cut and joined, with a convenient construction process
This is a matching connection component for the fiberglass reinforced plastic (FRP) pipeline system, which is formed as a single piece through the molding process.
Core feature
• Corrosion-resistant: Resistant to acids and alkalis, as well as various chemical media. Suitable for harsh environments such as those in the chemical industry and sewage treatment.
• High strength: The molded structure is dense, has strong pressure-bearing capacity, and provides reliable sealing.
• Lightweight: The weight is approximately only 1/4 of that of carbon steel flanges, making installation very convenient.
• Insulation and flame retardancy: Non-conductive, flame retardant, suitable for power and environmental protection applications
• Long lifespan: Anti-aging, anti-fatigue, and low maintenance cost
These are profile products produced through the extrusion molding process. In the figure, of them are FRP (fiberglass reinforced plastic) extruded profiles.
Core feature
• Material: Made with glass fiber as the reinforcing material and unsaturated polyester resin as the matrix, it is formed through continuous pultrusion and a curing process.
• Performance:
• Lightweight and high strength: The weight is only 1/4 of that of steel, and the strength is comparable to that of steel.
• Corrosion-resistant: Resistant to acids, alkalis, salt spray and chemical media. Suitable for humid and corrosive environments.
• Insulation and flame retardancy: Excellent electrical insulation properties. Some models also possess flame-retardant and anti-static features.
• Strong weather resistance: Resistant to ultraviolet rays and able to withstand high and low temperatures. It will not age or deform over a long period of use.
• Structure: The cross-sections are diverse (such as rectangular, slot-shaped, I-shaped, square tubes, etc.), and can be customized according to requirements. The figure shows a typical hollow/porous structure that balances strength and lightweight.
