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 enhanced water quality with our cutting-edge innovations.
Our advanced composite pipeline products are engineered with anti-bacterial and anti-scaling properties, ensuring the utmost safety of drinking water networks. Count on Shandong Donghong for dependable solutions that prioritize top-tier quality and innovation.
High Quality: The Blue Dream series is crafted from premium food-grade polyethylene resin, offering customers superior raw materials to 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, far surpassing the standard requirement of 1850MPA. This ensures superior 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 performing 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 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, mitigating secondary pollution and scaling within the pipes to maintain long-term consistency in pipeline efficiency. This synergy guarantees both hygiene and safety, contributing to a superior quality of life.
1.Electrofusion Welding: This method involves using specialized equipment to heat the pipe ends and fittings, melting the material and allowing them to fuse together.
2.Butt Fusion Welding: Similar to electrofusion welding, butt fusion welding involves heating the pipe ends and then pressing them together to create a seamless joint.
3.Flange Connections: Flange connections utilize flanges attached to the pipe ends, which are then bolted together with gaskets to create a secure seal.
4.Mechanical Couplings: Mechanical couplings are used to join pipe sections together using compression fittings or clamps, providing a quick and easy connection method.
5.Threaded Connections: Some steel wire reinforced PE composite pipes feature threaded ends, allowing them to be screwed together with compatible fittings or adapters
1.R & D team can be achieved from the source of raw materials independent design and development, manufacturing capacity and has independent intellectual property rights, independent development of wear-resistant materials with elasticity, independent production and application, the real mastery of the core science and technology to ensure product quality.
2.Donghong has a professional high pressure pipe fittings factory, which produces various types of high pressure pipe fittings for projects, and can also help customers to customise special pipe fittings according to customer requirements and project environment.
3.Donghong construction team is engaged in pipeline installation, pipe cleaning, pressure testing, drying, replacement, cathodic protection, hydraulic protection, fibre optic cable laying, pipeline lining repair HDPE, CIPP technology, PCM audio leakage detection and other specialised constructions around pipeline construction in the fields of mining, oilfield, civil, infrastructure and so on. After many years of case accumulation, we have summarised the construction experience in various complex operating environments such as mountains, paddy fields, ponds and so on.
