FRP pipes

Our Glass Fiber Reinforced FRP Pipe is a high-performance piping solution engineered for large-scale infrastructure projects in the municipal, industrial, and agricultural sectors. Manufactured by Hebei Ludi Environmental Protection Technology Co., Ltd., these pipes offer a modern and superior alternative to traditional materials like concrete, steel, and ductile iron. By utilizing an advanced filament winding process, we create a composite pipe that provides exceptional corrosion resistance, a long service life, and significant installation advantages, making it the premier choice for engineers, contractors, and distributors seeking reliability and long-term value.

 

 

Key Advantages of Our Composite Piping Systems
The primary benefit of our Glass Fiber Reinforced FRP Pipe lies in its complete immunity to corrosion. The inert composite materials will not rust, degrade from chemical exposure, or be affected by electrolysis, making them ideal for transporting potable water, wastewater, seawater, and industrial chemicals. This inherent resistance eliminates the need for costly coatings or cathodic protection, drastically reducing lifetime maintenance costs. Furthermore, our FRP pipes are up to 75% lighter than steel and 90% lighter than concrete pipes of the same diameter. This remarkable weight reduction lowers transportation costs, allows for the use of lighter installation equipment, and significantly speeds up project timelines, delivering direct cost savings to our clients.

Advanced Filament Winding Technology
The exceptional strength and performance of our Glass Fiber Reinforced FRP Pipe are derived from our precision manufacturing process. Each pipe is constructed in layers on a rotating mandrel. It begins with a resin-rich inner liner that acts as a seamless, hydraulically smooth, and impermeable corrosion barrier. Next, continuous, high-strength glass fiber rovings are saturated in a thermosetting resin (such as polyester or epoxy) and wound around the liner at computer-controlled, specific angles. This process builds the structural wall of the pipe, engineered to meet exact pressure and stiffness requirements. A final resin-rich exterior layer is added for protection against UV radiation and mechanical abrasion, ensuring durability in harsh environmental conditions. This multi-layer construction results in a monolithic pipe with predictable and superior engineering properties.

Our Commitment to Manufacturing Excellence
Our large-scale production facility is equipped with state-of-the-art, automated filament winding machines and curing systems, ensuring unparalleled product consistency and quality for even the largest orders. At Hebei Ludi, quality assurance is integrated into every step of the process. We conduct rigorous testing on all raw materials and maintain strict in-process controls. Critically, every section of our Glass Fiber Reinforced FRP Pipe, or a statistical sample based on project requirements, undergoes hydrostatic pressure testing to verify its structural integrity and guarantee it meets or exceeds international standards like ASTM and ISO. This commitment to quality ensures that you receive a product ready for immediate and reliable deployment in the field.

When you choose Ludi, you are not just buying pipe; you are gaining a partner dedicated to your project's success. We specialize in providing comprehensive OEM/ODM solutions, allowing us to manufacture pipes to your exact specifications, including custom diameters (up to 4000mm), pressure ratings, stiffness classes, and lengths. Our in-house engineering team can provide technical support to help you select the optimal product for your application. With extensive experience in global logistics, we ensure your order is securely packaged and efficiently delivered to your project site, anywhere in the world.

1. What standards do your FRP pipes comply with?
Our pipes are manufactured to meet major international standards, including ASTM D2996, AWWA C950, and ISO 10639, ensuring they meet strict criteria for quality, performance, and safety.

2. What methods are used to join the pipes?
We offer several reliable joining methods depending on the application, with the most common being a bell-and-spigot joint with a secure EPDM rubber O-ring seal. We also provide butt-wrap lamination joints and flanged connections for easy integration with other equipment.

3. What is the expected service life of your Glass Fiber Reinforced FRP Pipe?
Due to their inherent corrosion resistance and robust construction, our FRP pipes are designed for a maintenance-free service life of 50 years or more, even in aggressive environments.
