Welcome to Shandong Donghong Pipe Industry Co., Ltd.! We proudly offer a remarkable range of high-quality drinking water pipes, specifically designed to address common issues such as microbial breeding, yellow water, corrosion, scaling, and reduced water transmission capacity. Say goodbye to secondary pollution and welcome superior water quality with our state-of-the-art innovations.
Our cutting-edge composite pipeline products boast anti-bacterial and anti-scaling properties, ensuring the utmost safety and purity of drinking water networks. Trust Shandong Donghong for reliable solutions that prioritize excellence and innovation.
High Quality: Our Blue Dream series is meticulously crafted from premium food-grade polyethylene resin. This ensures our customers receive superior raw materials, guaranteeing the long-term performance and reliability of our pipelines.
Enhanced Steel Wire: We incorporate copper-plated steel wire that complies with GB/T14450 standards and features an impressive strength of 2050MPA, significantly exceeding the standard requirement of 1850MPA. This ensures unparalleled durability, reliability, and performance in the most demanding conditions.
Adhesive Resin: Our patented adhesive resin, developed using proprietary technology, offers extraordinary adhesion to steel wire and outstanding process adaptability. This innovative solution ensures our pipes are both reliable and robust, capable of performing exceptionally well in diverse and challenging environments.
Our Advantages
Anti-Scaling and Low Flow Resistance: By employing the lotus leaf effect principle, our design achieves a low contact angle (>105°) on the inner wall of the pipe. This groundbreaking innovation prevents scaling and reduces wetting tension, significantly boosting hydraulic transportation efficiency.
The Blue Dream series provides a performance guarantee for customers' high-quality water needs. It effectively mitigates secondary pollution and scaling within the pipes, ensuring long-term consistency in pipeline efficiency. This synergy guarantees both hygiene and safety, contributing to an elevated quality of life.
1. Electrofusion Welding: This advanced technique employs specialized equipment to meticulously heat the pipe ends and fittings. The material melts, seamlessly fusing together to form an unbreakable bond.
2. Butt Fusion Welding: In this precise process, similar to electrofusion welding, the pipe ends are expertly heated and then pressed together, creating a smooth, seamless joint for unparalleled integrity.
3. Flange Connections: For reliable connections, flange connections feature flanges securely attached to the pipe ends. These flanges are then bolted together with gaskets to ensure a robust and secure seal.
4. Mechanical Couplings: This efficient method uses mechanical couplings to join pipe sections. Compression fittings or clamps make the connection quick, easy, and effective.
5. Threaded Connections: Certain steel wire reinforced PE composite pipes boast threaded ends, allowing for easy assembly with compatible fittings or adapters by simply screwing them together.
1. Our R&D team excels in pioneering from the very inception of raw materials, crafting innovative designs, and developing robust manufacturing capabilities. With proprietary intellectual property rights, we independently create and produce wear-resistant materials with superior elasticity. Mastering core technology ensures impeccable product quality.
2. Donghong boasts a state-of-the-art high-pressure pipe fittings factory, specializing in a diverse range of high-pressure pipe fittings tailored for various projects. We also provide bespoke solutions, customizing special pipe fittings to meet specific customer requirements and adapt to unique project environments.
3. The Donghong construction team offers comprehensive pipeline services, including installation, cleaning, pressure testing, drying, replacement, cathodic protection, hydraulic protection, fibre optic cable laying, HDPE lining repair, CIPP technology, and PCM audio leakage detection. With extensive experience across diverse fields such as mining, oilfields, civil, and infrastructure projects, we have honed our expertise even in challenging environments like mountains, paddy fields, and ponds.
