HDPE Pipe
Haosail cage system mainly includes: cage handrail pipe, cage floating pipe, anti-slip pedal, cage fittings etc. All these parts are made from Grade 100 HDPE, using advanced molding equipment, mature production technology and completed inspection method, to ensure them comply with national standard and industry standard.
Deep-sea aquaculture has rapidly evolved as a vital component of global food security, offering a sustainable pathway to meet the escalating demand for seafood while alleviating pressure on overexploited wild fish populations. At the heart of modern offshore aquaculture systems, particularly those utilizing cage-based farming, lies a critical structural element: the floating framework that supports the entire operation. Among the materials employed for this purpose, High-Density Polyethylene (HDPE) has emerged as the material of choice for main floating pipes, revolutionizing the industry with its unique combination of durability, adaptability, and environmental compatibility. This article provides a holistic introduction to HDPE main floating pipes, exploring their role in deep-sea aquaculture, their inherent advantages, and their contribution to the advancement of sustainable marine farming practices.
HDPE main floating pipes are cylindrical structures fabricated from high-density polyethylene, a thermoplastic polymer renowned for its exceptional strength-to-density ratio, chemical resistance, and flexibility. These pipes form the foundational framework of floating aquaculture cages, serving as the primary buoyant component that supports the weight of the net enclosure, feed systems, monitoring equipment, and the biomass of farmed fish. Unlike traditional materials such as steel, wood, or concrete, HDPE is inherently resistant to corrosion, a property that makes it exceptionally suited to the harsh marine environment. Saltwater, UV radiation, and temperature fluctuations-common challenges in offshore settings-have minimal impact on HDPE's structural integrity, ensuring longevity and reliability over decades of use.
The design and engineering of HDPE floating pipes are tailored to meet the demanding conditions of deep-sea aquaculture. Buoyancy is a fundamental consideration, as these pipes must displace sufficient water to support not only their own weight but also the dynamic loads imposed by waves, currents, and the cage's operational components. Engineers optimize the diameter, wall thickness, and overall geometry of HDPE pipes to achieve a balance between buoyancy and structural resilience. Advanced computational models are often employed to simulate extreme scenarios, such as storm surges or sudden increases in biomass, ensuring that the pipes maintain stability under stress. Furthermore, the modular nature of HDPE systems allows for scalability and adaptability. Farms can be easily expanded or reconfigured by connecting additional pipe sections using clamps, bolts, or thermal fusion welding-a process that creates seamless, leak-proof joints. This modularity not only simplifies installation and maintenance but also reduces downtime during repairs or upgrades.

HDPE, lightweight high-strength alloy materials and other new materials are adopted in the structure. Computer control, various anti-corrosive, anti fouling (attachments) and anti-aging technologies greatly improve the overall structural strength and flexibility of deep-sea aquaculture net cage, double the service life of the cage, highly reduce the daily maintenance and the cost of aquaculture in unit volume, and improve economic benefits.
