Description

• Custom Geometric Flexibility for Complex Routing The multi-angle fabrication process allows for the production of segmented elbows (e.g., 15°, 22.5°, 30°), tees, and crosses tailored to specific site topography. This design flexibility eliminates the need for field-modifying standard parts or forced pipe bending, significantly reducing mechanical stress on the pipeline and simplifying installation in constrained environments.
• Homogeneous Butt-Fused Joints for Leak-Free Security The use of thermal butt-fusion technology creates a molecular bond at the segmented interfaces that is equal to or stronger than the pipe itself. This monolithic structure eliminates the potential leak points inherent in mechanical or gasketed joints, providing a zero-leak rate that is critical for environmental protection and long-term pressurized water delivery.
• High-Grade PE100 Material for Extended Service Life Manufactured from premium PE100 resin, these fittings exhibit excellent resistance to Slow Crack Growth (SCG) and Rapid Crack Propagation (RCP). This material stability ensures the system can withstand constant operating pressures (up to PN16/SDR11) and provides a documented service life exceeding 50 years under rated temperatures and conditions.
• Large-Diameter Capability for High-Flow Systems Unlike injection molding limited by mold dimensions, these fabricated HDPE fittings support a size range from OD 90mm up to OD 2000mm. This scalability ensures that large-scale infrastructure projects, such as municipal mainlines and industrial effluent systems, maintain consistent material properties and hydraulic efficiency across the entire pipe diameter spectrum.
• Chemical and Corrosion Inertness in Harsh Media The non-polar polyethylene structure provides high resistance to a broad range of chemical media, including strong acids and alkalis, without the risk of electrochemical corrosion or scaling. For project contractors, this eliminates the need for expensive internal linings or external coatings required by steel or ductile iron alternatives, reducing long-term maintenance costs.
• Optimized Hydraulic Efficiency via Low Friction Surface The smooth internal walls of the fabricated segments feature a very low roughness coefficient, which minimizes fluid turbulence and friction loss. This engineering property results in lower pumping energy requirements over the life of the project and prevents the buildup of bacteria or sediment, maintaining water quality and flow capacity.
• Lightweight Modular Structure for Reduced Logistics Costs The high strength-to-weight ratio of HDPE makes these segmented fittings significantly lighter than metal counterparts of the same pressure rating. This reduces the requirement for heavy lifting machinery during onsite assembly and lowers international shipping costs, providing a more cost-effective logistics solution for remote infrastructure projects.
• Environmental Strain Resistance for Earthquake-Prone Areas The inherent flexibility of the segmented HDPE structure, combined with its weldability, allows the piping system to absorb ground movement and seismic shifts. This adaptability prevents catastrophic brittle fractures common in rigid piping, ensuring the operational integrity of critical firefighting and municipal networks in unstable geological zones.

Scope of application

• Large-Diameter Municipal Water Mainlines In municipal infrastructure, these segmented HDPE pipe fittings serve as critical nodes for urban pressurized water supply and distribution networks. They are used for directional changes in main pipelines (OD 630mm to 2000mm), facilitating the stable transport of potable water at ambient temperatures. The butt-fusion joint integrity ensures zero leakage under standard operating pressures ranging from 0.6Mpa to 1.6Mpa, accommodating urban soil settlement.
• Mining Tailings and Slurry Transportation For the mining industry, fabricated HDPE fittings are integrated into abrasive slurry and tailings discharge systems. They function as high-durability elbows and tees for conveying mineral concentrates and waste mixtures. The PE100 material's high resistance to environmental stress cracking and mechanical abrasion makes it suitable for handling solid-liquid mixtures in rugged terrain where custom-angled configurations are frequently required.
• Industrial Chemical Processing and Drainage In industrial chemical facilities, these fittings are utilized for the safe conveyance of corrosive process fluids and industrial wastewater. They are highly compatible with systems transporting dilute acids, alkalis, and various chemical effluents that would otherwise corrode metal piping. The segmented design allows for complex layouts in chemical plants, ensuring a chemically inert flow path that maintains structural integrity over long-term exposure.
• Large-Scale Agricultural Irrigation Systems These segmented fittings are applied in modern agricultural irrigation networks to adapt mainline pipes to diverse field layouts and topographical elevations. They manage the distribution of raw water from reservoirs or pump stations to secondary irrigation lines. The modular design of fabricated HDPE components facilitates efficient water transport in outdoor environments, resisting UV exposure and temperature fluctuations typical of extensive farming operations.
• Landfill Leachate Collection and Disposal In waste management infrastructure, fabricated HDPE fittings are essential for leachate collection systems within landfill cells. They are used to route contaminated fluids (leachate) through drainage layers to treatment facilities. Due to their exceptional resistance to complex chemical media and biological degradation, these fittings ensure the environmental containment of hazardous fluids under varying burial depths and soil loads.
• Marine and Desalination Intake Pipelines In marine engineering, fabricated fittings are used for seawater intake and brine discharge systems in desalination plants and offshore facilities. They handle the transport of high-salinity seawater and concentrated brine in submerged or coastal environments. The non-corrosive nature of the PE100 resin eliminates the risk of saltwater pitting, which is a common failure mode for traditional metallic piping in maritime applications.
• Subsurface Fire Protection Rings For large-scale industrial warehouses and manufacturing hubs, these fittings are used to construct underground fire-fighting loop systems. They provide reliable connections for high-pressure fire mains that must remain operational during seismic events or ground shifts. The flexibility of the segmented structure allows the system to absorb mechanical energy, ensuring the continuous availability of water for emergency fire suppression.
