Our tees are manufactured with a one-piece molding process without weld seams. Their extremely smooth and flat interior effectively prevents impurity accumulation and avoids the interlayer separation and leakage accidents.
FRP molded elbows can effectively resist fluid impact and are commonly used for the transportation of high-speed fluids at pipe turning points. We offer custom curvature radius options to adapt to the resistance of your fluid.
The leakage rate of the FRP flange is less than 0.01%, and the matching bolts are easy to disassemble. They are used for connecting pipelines in the chemical and power systems that require regular maintenance and inspection.
FRP crosses are used in pipeline systems with branches going up, down, left, and right. It connects pipelines in four directions, simplifying the installation process and increasing space utilization.
Its gap variation at its sealing connection is < 0.05mm, which completely prevents end leakage. It does not require metal bolts, thus avoiding the collapse accident of the end bolts.
They have different structural shapes. They are used for the connections in building structures, enhancing the coordination and seismic resistance of the entire building system.
It connects multiple FRP reinforcement bars, replacing steel bars. The load-bearing capacity of FRP bars is stronger than ordinary steel bars. They provide higher durability and safety under loads.
The low friction coefficient of FRP nuts and bolts gives a higher anti-loosening torque, ensuring no loosening for 72 hours in vibration tests and avoiding safety hazards caused by loosening.
Features of FRP Connector
The specific strength of FRP connectors is 1.5 times that of steel. They significantly reduce the overall weight under the same load-bearing capacity.
FRP connectors can withstand various corrosive environments, ranging from pH 1 to 14. The vinyl resin system ensures stable performance and no rust for over 20 years.
FRP materials are insulated and do not generate stray currents. This eliminates electric shock and electrochemical corrosion, and extends the structural lifespan by more than three times.
The thermal conductivity of the FRP connectors is only 0.3 W/m·K, which offers excellent insulation performance and enhances the insulation efficiency of the overall building.
The FRP connectors with built-in ultraviolet absorbers can withstand 10 years of outdoor exposure without fading or cracking.
The low density of FRP connectors makes them easy to cut with ordinary tools. The simple structure of connectors is very convenient for the mold-based integrated molding process.
Insulation Safety
FRP connectors are naturally insulating, with a volume resistivity of over 1×10¹² Ω·cm. They can prevent electric leakage of buildings and equipment in various industries, which reduces human casualties.
Long Service Life
Our FRP connectors have outstanding mechanical properties and corrosion resistance after strict manufacturing processes, effectively preventing internal corrosion, cracking, and delamination of equipment and buildings. This ensures your expensive equipment operates long-term and stably.
Applications of FRP Connector
FRP connectors are corrosion-resistant and can withstand the corrosive environment underground. They have good cutting properties and can be used for concrete walls and soil nails in shield tunneling.
Its light self-weight and high-strength characteristics enable it to withstand extremely large dynamic loads, and are used as the cables of suspension bridges and the prestressed steel bars in concrete bridges.
The FRP bolt connection system effectively withstands the high-salt-spray environment at sea. It solves the corrosion problem in offshore engineering structures and significantly extends their lifespan. The smooth surface reduces the attachment of marine organisms.
The sulfur dioxide gas in industrial wastewater is corrosive, and epoxy vinyl ester FRP connectors can resist sulfides. Their smooth inner walls prevent scaling, and they have an obvious energy-saving effect during long-term operation.
FRP pipe clamps can withstand continuous exposure to highly concentrated corrosive liquids, effectively solving the acid overflow problem in chemical processing plants.
The FRP support has excellent insulation properties and can completely block the stray current return path, eliminating electrochemical corrosion fundamentally. It is widely used in evacuation platforms and cable supports of subway lines.
FRP is a glass fiber composite material with excellent comprehensive properties and stable chemical properties. It does not react with metals in normal environments. However, metals are prone to electrochemical reactions in a high-humidity environment. Therefore, we recommend adding rubber gaskets between it and the metal.
Under long-term loading conditions, FRP components will undergo slight creep. However, we took this into account during the design process. We design FRP connectors according to their elasticity and the applied stress, ensuring that the deformation within 50 years is less than 1.6 times the initial value. This avoids potential safety hazards to your project caused by creep.
Aluminum-magnesium alloys are also lightweight but have narrower adaptability. When exposed to carbon steel, they are easy to corrode electrochemically, leading to rusting.
The fatigue limit of aluminium-magnesium alloy is lower than that of FRP. Its connecting parts need to be designed to meet the fatigue limit to prevent crack formation under long-term loads. However, FRP has a stronger fatigue performance.
Furthermore, the prices of aluminum-magnesium alloy raw material are affected by the market, while the prices of FRP are stable.
For FRP connectors used in the food industry, the resin base material is food-grade quality and has FDA certification.
During production, we avoid adding antimony trioxide to prevent its biological toxicity and loss to your food materials. We ensure your food complies with food safety regulations.
The surfaces of the food-grade FRP connectors have all been polished, achieving a mirror-like smoothness on the surfaces that contact food, thereby preventing the residue of microorganisms and pathogens.
What Are FRP Connectors?
FRP connectors are connection components made of FRP composite materials with different diameters, lengths, and shapes. They are used in industrial projects to connect fiberglass pipes or to connect fiberglass pipes to other materials.
FRP connectors overcome the disadvantages of traditional connectors, including corrosion failure, excessive self-weight, and poor fatigue resistance. This article will introduce eight common types of FRP connectors and their selection criteria, helping you choose the correct connector for your project.
How to Choose FRP Connectors?
Environmental Factor
Corrosivity
For environments with strong acids and alkalis, such as the salt spray environment and the rock and soil environment, we recommend FRP connectors made of vinyl resin.
Traditional metal connectors can not cope with highly corrosive environments well. Vinyl materials have excellent chemical stability, which protects the FRP connectors from corrosion caused by salt fog and marine pollutants.
The salts and acids in the rock and soil have high corrosiveness and easily corrode the metal connectors, leading to anchoring failure. The natural corrosion resistance of FRP connectors ensures a long-term anchoring effect, thereby protecting the structure.
Ultraviolet Exposure
Overseas bridges withstand long-term exposure to sunlight. Prolonged ultraviolet radiation causes the resin in FRP to degrade, affecting the performance and mechanical strength of the FRP connectors.
For cross-sea bridges that are exposed to high-intensity ultraviolet rays for a long time, we recommend applying an anti-UV coating on the surface of the FRP connectors or adding UV absorbers to the resin raw materials.
Performance Requirement
Load-Bearing Requirements
For building structures with high load requirements, we recommend FRP connectors made by the pultrusion process. The pultrusion process ensures the continuity of the fibers, allowing the load to be efficiently transferred along the fibers. The tensile strength and the load-bearing capacity per unit area of the pultruded FRP connectors are much higher than those of other processes.
Seismic Resistance Requirements
Buildings such as bridges and tunnels are prone to damage under impacts of strong earthquakes. FRP connectors made of impact-resistant resin absorb the energy of vibrations and prevent structural collapse. Moreover, FRP connectors produced by pultrusion and molding processes have better seismic resistance. They disperse the impact force and avoid internal tearing caused by assembled connectors.
Cutting Property
FRP is easy to cut and does not damage the cutting tools. A rotary cutting machine can easily cut FRP connectors during tunnel construction. This significantly saves construction time and material consumption. We offer pre-cutting services and ensure precise cutting dimensions, saving installation time for your project.
