Welcome to Shandong Donghong Pipe Industry Co., Ltd.! Our company specializes in an exceptional range of high-quality drinking water pipes designed to combat prevalent issues such as microbial breeding, yellow water, corrosion, scaling, and diminished water transmission capacity. Bid farewell to secondary pollution and embrace unparalleled water quality with our cutting-edge innovations.
Our advanced composite pipeline products are meticulously engineered with anti-bacterial and anti-scaling properties, ensuring the utmost safety of drinking water networks. Trust Shandong Donghong for dependable solutions that prioritize top-tier quality and breakthrough innovation.
High Quality: The Blue Dream series is crafted from premium food-grade polyethylene resin, offering customers superior raw materials that guarantee the long-term performance and reliability of the pipeline.
Enhanced Steel Wire: We utilize copper-plated steel wire that meets GB/T14450 standards and boasts a remarkable strength of 2050MPA, significantly surpassing the standard requirement of 1850MPA. This ensures unparalleled durability, reliability, and performance under the most challenging conditions.
Adhesive Resin: Our patented adhesive resin, developed with proprietary technology, offers exceptional adhesion to steel wire and outstanding process adaptability. This innovative solution guarantees our pipes are both reliable and robust, capable of excelling in various challenging environments.
Our Advantages
Anti-Scaling and Low Flow Resistance: Utilizing the lotus leaf effect principle, our design creates a low contact angle (>105°) on the inner wall of the pipe. This advanced innovation prevents scaling and reduces wetting tension, significantly enhancing hydraulic transportation efficiency.
The Blue Dream series ensures a performance guarantee for customers' high-quality water needs, effectively mitigating secondary pollution and scaling within the pipes. This synergy maintains long-term consistency in pipeline efficiency, guaranteeing both hygiene and safety, and contributing to an elevated quality of life.
1. Electrofusion Welding: This advanced technique employs specialized equipment to heat the pipe ends and fittings, effectively melting the material to fuse them together seamlessly. It ensures a strong, durable connection ideal for high-stress environments.
2. Butt Fusion Welding: In this robust process, the pipe ends are heated and pressed together to form a flawless, continuous joint. This method guarantees an exceptionally strong bond, making it perfect for long-term, high-pressure applications.
3. Flange Connections: Flange connections are achieved by attaching flanges to the pipe ends, which are then bolted together with gaskets to ensure a secure and leak-proof seal. This method is ideal for installations requiring frequent disassembly or maintenance.
4. Mechanical Couplings: For a quick and efficient solution, mechanical couplings join pipe sections using compression fittings or clamps. This method provides a reliable connection that is easy to install and ideal for temporary or emergency repairs.
5. Threaded Connections: Certain steel wire reinforced PE composite pipes come with threaded ends, enabling them to be screwed together effortlessly with compatible fittings or adapters. This method offers versatility and ease of assembly for various applications.
1. Our Research & Development (R&D) team excels with independent design and development of raw materials, contributing to manufacturing prowess. We hold exclusive intellectual property rights, enabling us to independently develop, produce, and apply wear-resistant materials with unmatched elasticity. This mastery over core science and technology ensures impeccable product quality.
