Description

• High-Density Material Structure Utilizing high-grade Polyvinyl Chloride with a density of 0.9~1.2g/cm³, these fittings offer a superior strength-to-weight ratio compared to traditional metal alternatives. The lightweight nature of the material significantly lowers logistics costs and simplifies on-site handling, enabling faster installation cycles without the need for heavy lifting equipment.
• Hydraulically Optimized Inner Surface The smooth internal bore minimizes friction and fluid turbulence, resulting in a significantly lower Hazen-Williams friction coefficient. By reducing pressure loss across the fitting, the system maintains higher flow rates, which allows project engineers to optimize pump sizing and reduce long-term energy consumption for the end-user.
• Chemical and Corrosion Inertness The thermoplastic properties of uPVC provide inherent resistance to acids, alkalis, and salts, preventing electrochemical corrosion and scaling. This material stability ensures the fittings do not degrade when buried in aggressive soil conditions or when transporting treated water, effectively extending the system's service life and reducing maintenance frequency.
• Thermal Stability and Weather Resistance Designed to operate within a temperature range of -15°C to 55°C, these fittings maintain structural integrity under varying environmental conditions. This wide operating window, combined with UV-stabilized compounds, ensures reliable performance in both sub-zero buried applications and high-temperature surface-level tropical installations.
• Non-Toxic and Lead-Free Composition The PVC material is formulated to be healthy and non-toxic, ensuring that water quality remains unaffected by leaching or bacterial growth. This compliance with potable water safety standards makes these fittings suitable for residential building water supply systems and food-grade agricultural irrigation.
• Solvent Cement Jointing System The fittings are designed for cold solvent welding, creating a chemical bond that becomes the strongest point of the pipe system. This simple yet effective connection method eliminates the need for specialized welding electricity or heavy machinery, providing a cost-effective and leak-proof joint that withstands high-pressure surges.
• High Dielectric Strength As a non-conductive material, these PVC water supply fittings provide excellent electrical insulation, protecting the pipeline from galvanic corrosion and stray currents. This property is particularly valuable in municipal engineering where water lines run adjacent to underground power cables, ensuring the long-term safety of the infrastructure.

Scope of application

• Municipal Water Supply InfrastructureIn urban and rural municipal engineering, these uPVC pipe fittings serve as critical connectors for potable water distribution networks. They are utilized in mainline extensions and residential service connections to transport treated water at ambient temperatures. The material's resistance to soil-borne chemicals and galvanic corrosion ensures long-term structural integrity in buried environments without the risk of heavy metal leaching or water quality degradation.
• Commercial and Residential Building ServicesWithin the construction sector, these fittings are integrated into cold water plumbing systems for high-rise and multi-family residential projects. They facilitate the vertical and horizontal distribution of pressurized water from booster pump sets to terminal fixtures. The high dielectric strength and low noise transmission of polyvinyl chloride make them ideal for indoor installations where electrical insulation and acoustic comfort are necessary engineering considerations.
• Agricultural Irrigation and Sprinkler SystemsFor large-scale agricultural projects and golf course engineering, these fittings are used to construct durable high-pressure irrigation headers and lateral lines. They are engineered to handle raw water sourced from wells or reservoirs, often containing dissolved fertilizers or trace agricultural chemicals. Their UV-resistant properties and robust mechanical strength allow for reliable performance in both shallow-buried and surface-exposed configurations under varying climatic conditions.
• Industrial Cooling and Circulating Water LoopsIn power engineering and HVAC systems, these industrial grade PVC fittings manage the circulation of cooling water and condensate. They are frequently applied in air conditioning cooling tower loops where the media is typically water or mild glycol solutions. The smooth internal bore minimizes friction loss, optimizing the efficiency of circulating pumps and preventing the buildup of scale that commonly affects metal piping in continuous-flow thermal exchange systems.
• Aquatic and Swimming Pool Filtration SystemsThese fittings are widely adopted in the pool and spa industry for water circulation and filtration piping. They are specifically suited for transporting water treated with chlorine, bromine, or salt-based sanitizing agents. The non-reactive nature of the PVC material prevents chemical erosion from concentrated pool chemicals, ensuring leak-proof joints in high-turnover filtration cycles.
• Mining and Shaft Sinking EngineeringIn mining and petroleum engineering, these fittings are utilized for dewatering operations and the transport of non-corrosive process water. They are particularly effective in shaft sinking projects where lightweight components are required to reduce the load on vertical support structures. The ability to withstand external pressure and chemical resistance to mineral-rich groundwater makes them a cost-effective alternative to lined steel in low-to-medium pressure mining applications.
