Welcome to Shandong Donghong Pipe Industry Co., Ltd.! Discover a remarkable array of high-quality drinking water pipes specifically designed to tackle common issues such as microbial growth, yellowing water, corrosion, scaling, and reduced water transmission capacity. Say goodbye to secondary pollution and enjoy superior water quality with our state-of-the-art innovations.
Our cutting-edge composite pipeline products are meticulously engineered with anti-bacterial and anti-scaling properties, ensuring the highest safety standards for drinking water networks. Trust Shandong Donghong for reliable solutions that emphasize unparalleled quality and innovation.
High Quality: The Blue Dream series is expertly crafted from top-tier food-grade polyethylene resin, providing customers with premium raw materials that ensure the long-term performance and reliability of the pipeline.
Enhanced Steel Wire: We employ copper-plated steel wire that meets GB/T14450 standards, boasting an impressive strength of 2050MPA, significantly exceeding the standard requirement of 1850MPA. This ensures exceptional durability, reliability, and performance even under the most demanding conditions.
Adhesive Resin: Our proprietary adhesive resin, developed through our unique technology, offers superior adhesion to steel wire and exceptional process adaptability. This innovative solution ensures our pipes are both robust and reliable, capable of excelling in various challenging environments.
Our Advantages
Anti-Scaling and Low Flow Resistance: By leveraging the lotus leaf effect principle, our design achieves a low contact angle (>105°) on the pipe's inner wall. This innovation prevents scaling and reduces wetting tension, drastically enhancing hydraulic transportation efficiency.
The Blue Dream series guarantees superior performance for customers' high-quality water needs, reducing secondary pollution and scaling within the pipes to maintain consistent long-term pipeline efficiency. This synergy ensures both hygiene and safety, contributing to an elevated quality of life.
1. Electrofusion Welding: Utilizing state-of-the-art equipment, this method involves heating the pipe ends and fittings to their melting points, allowing the material to seamlessly fuse together, ensuring an unyielding bond.
2. Butt Fusion Welding: This technique mirrors electrofusion welding by heating the pipe ends, but instead of fittings, the ends are directly pressed together to form a flawless, integral joint.
3. Flange Connections: This method employs flanges affixed to the pipe ends, which are subsequently bolted together with gaskets, ensuring a secure, leak-proof seal.
4. Mechanical Couplings: Ideal for swift and efficient connections, mechanical couplings use compression fittings or clamps to join pipe sections, providing a robust and reliable connection.
5. Threaded Connections: Certain steel wire reinforced PE composite pipes come with threaded ends, allowing them to be effortlessly screwed together with compatible fittings or adapters, ensuring versatility and ease of installation.
1. Our R&D team stands at the forefront of innovation, designing and developing raw materials independently. With robust manufacturing capabilities and proprietary technology, we produce wear-resistant materials known for their exceptional elasticity. This core scientific prowess ensures unmatched product quality and reliability.
2. Donghong boasts a state-of-the-art high-pressure pipe fittings factory, producing a wide array of fittings for diverse projects. We offer bespoke solutions, customizing pipe fittings to meet specific customer requirements and project environments, ensuring optimal performance and satisfaction.
3. The Donghong construction team specializes in pipeline installation, maintenance, and advanced protection techniques. From pipe cleaning and pressure testing to fibre optic cable laying and PCM audio leakage detection, our expertise spans mining, oilfield, civil, and infrastructure sectors. Drawing from extensive experience in challenging environments like mountains and paddy fields, we deliver superior pipeline construction solutions.
