Welcome to Shandong Donghong Pipe Industry Co., Ltd.! Our company specializes in delivering an exceptional array of high-quality drinking water pipes, meticulously designed to combat common issues such as microbial breeding, yellow water, corrosion, scaling, and reduced water transmission capacity. Bid farewell to secondary pollution and embrace enhanced water quality with our state-of-the-art innovations.
Our cutting-edge composite pipeline products are ingeniously engineered with both anti-bacterial and anti-scaling properties, guaranteeing the utmost safety and purity of drinking water networks. Trust Shandong Donghong for reliable solutions that prioritize unparalleled quality and groundbreaking innovation.
High Quality: The Blue Dream series is expertly crafted from premium food-grade polyethylene resin, providing customers with superior raw materials to ensure the long-term performance and reliability of the pipeline.
Enhanced Steel Wire: Our pipes utilize copper-plated steel wire that meets GB/T14450 standards, boasting an impressive strength of 2050MPA, significantly surpassing the standard requirement of 1850MPA. This ensures unparalleled durability, reliability, and performance even under the most demanding conditions.
Adhesive Resin: Our proprietary adhesive resin, developed with cutting-edge technology, offers outstanding adhesion to steel wire and superior process adaptability. This innovative solution guarantees that our pipes are both reliable and robust, 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 inner wall of the pipe. This innovation effectively prevents scaling and reduces wetting tension, significantly boosting hydraulic transportation efficiency.
The Blue Dream series offers a performance guarantee for customers' high-quality water needs, effectively mitigating secondary pollution and scaling within the pipes. This ensures long-term consistency in pipeline efficiency, guaranteeing hygiene and safety, and thereby contributing to an enhanced quality of life.
1. Electrofusion Welding: Utilizing state-of-the-art equipment, this technique heats the pipe ends and fittings to a high temperature, causing the material to melt and seamlessly fuse. This results in a strong, reliable bond.
2. Butt Fusion Welding: By applying heat to the pipe ends and pressing them together, butt fusion welding creates a flawless, seamless joint. This method ensures robust and enduring connections.
3. Flange Connections: This method employs flanges affixed to the pipe ends, which are then bolted together with precision-engineered gaskets to ensure a tight, secure seal, enhancing durability and reliability.
4. Mechanical Couplings: Designed for ease and efficiency, mechanical couplings join pipe sections using compression fittings or clamps. This method offers a swift, straightforward solution for connecting pipes.
5. Threaded Connections: Featuring threaded ends, some steel wire reinforced PE composite pipes can be quickly and securely screwed together with compatible fittings or adapters, ensuring a highly reliable connection.
1. Our state-of-the-art R & D team excels from the very beginning, with unmatched capabilities in the independent design and development of raw materials.
