To meet the diverse construction demands of municipal water supply, hydraulic engineering, and pipe network renovation, and continuously optimize our supporting product portfolio for pipe connections, our mature Restrained Flange Adaptor for PE serves as a standardized, safe, efficient, and durable connection solution for various pressure pipeline projects. Developed to address core connection challenges between PE pipes, flange equipment, and ductile iron pipes, this product features an advanced structural design, stringent manufacturing techniques, and stable operational performance, making it suitable for complex engineering scenarios.
PE pipes are commonly used in pipeline engineering due to their excellent toughness, outstanding corrosion resistance, and cost-effectiveness. However, ensuring a reliable connection between PE pipes and traditional flange fittings, as well as ductile iron pipes, has been a significant challenge in pipe network construction and renovation. Conventional connection methods can lead to issues such as pipe slippage, seal leakage, and axial displacement, undermining the operational stability of pipe networks and increasing long-term maintenance costs. To tackle these industry challenges, our R&D team has optimized the design of the restrained flange adaptor, effectively resolving common issues related to sealing performance, position fixation, and compatibility in PE pipe flange connections.
Our Restrained Flange Adaptor for PE offers notable core technical advantages and superior performance compared to similar products in the industry. Constructed from GGG50/40 ductile iron and fitted with A2-70 stainless steel fastening bolts, it ensures high structural strength and strong impact resistance, even in harsh outdoor construction environments. The surface features a fusion-bonded epoxy coating thicker than 250 microns, adhering to high-end industrial anti-corrosion standards. This coating effectively resists erosion from acids, alkalis, moisture, and groundwater, significantly extending the product's service life. Fitted with EPDM rubber gaskets that comply with EN681-1 standards, the sealing system provides stable and reliable performance, preventing water seepage and leakage under high-pressure and long-term operating conditions.
Regarding performance and compatibility, this adaptor supports multiple pressure ratings, including PN10, PN16, and PN25, and accommodates mainstream pipe diameters ranging from DN50 to DN300, fully meeting the requirements of high and low-pressure water supply, drainage, irrigation, and other pipeline projects. Its built-in axial thrust restraint structure firmly locks the pipe in place, preventing slippage and displacement caused by pressure fluctuations and water impact. This eliminates the need for additional fixing brackets and greatly enhances the safety of pipeline operations. Manufactured in strict accordance with ISO2531 and EN545 international standards, it boasts strong universal compatibility, enabling quick, stable connections between PE pipes and ductile iron pipes, valves, water pumps, and other flange equipment, making it suitable for new pipe network construction, old pipe network renovation, and equipment connection projects.
Compared to traditional pipe connection fittings, our Restrained Flange Adaptor for PE offers significant advantages in construction efficiency and cost control. Its lightweight modular structure allows for quick, welding-free installation with low construction torque and no need for complex equipment. This approach shortens the construction cycle by over 30% and reduces labor and engineering costs. The product is suitable for various applications, including surface-laid and buried pipe networks, reclaimed water delivery, industrial water transportation, and municipal rainwater drainage systems.
With years of extensive experience in the pipe fitting industry, our company is committed to market-oriented development and focuses on addressing practical engineering challenges while continuously enhancing product craftsmanship and performance. The wide application of the Restrained Flange Adaptor for PE further enriches our product line and fills a gap in high-efficiency flange connection solutions for PE pipes. Moving forward, we will continue to expand our presence in municipal pipe networks, water conservancy projects, and industrial fluid transportation. We are dedicated to developing high-performance, highly compatible, and cost-effective pipe fittings, providing comprehensive pipeline engineering solutions for global clients and supporting the successful implementation of various infrastructure projects.
