Product Overview
Crafted from high-purity polyvinylidene fluoride (PVDF) resin through advanced injection molding, it delivers exceptional resistance to aggressive chemicals, extreme temperature fluctuations, and sustained mechanical stress. The female flare connections feature precision-machined sealing surfaces that create a tight, leak-free seal when paired with compatible flare nuts, enabling seamless integration into pipelines across chemical processing, semiconductor manufacturing, and water treatment plants. This union tee serves as a critical junction component, ensuring unobstructed fluid flow while maintaining system integrity in demanding operational environments.
Features
Superior Corrosion Resistance: Withstands prolonged exposure to concentrated acids (including 98% sulfuric acid, 65% nitric acid), strong alkalis (50% sodium hydroxide), and organic solvents (acetone, methanol), maintaining structural integrity without degradation.
Wide Temperature Range: Operates reliably from -20°C to +120°C, with minimal thermal expansion coefficient (≤80×10⁻⁶/°C) that prevents loosening of connections during temperature cycles.
High Pressure Rating: Maintains structural stability under 14 bar (200 psi) working pressure at 12°C, with a burst pressure exceeding 42 bar (600 psi) for enhanced safety in high-pressure hydraulic and pneumatic systems.
Precision Engineering: Female flare design with 37° sealing angle ensures easy alignment during installation, while the union structure allows for disassembly and maintenance without cutting pipelines, minimizing downtime.
Longevity: Resistant to UV radiation, oxidation, and microbial growth, with an expected service life of 15+ years in continuous industrial operation, outperforming traditional metal or PVC fittings.
Applications
Chemical Processing: Ideal for transferring corrosive reaction intermediates in pharmaceutical batch reactors, petrochemical distillation units, and specialty chemical blending systems.
Semiconductor Industry: Used in ultra-pure water (UPW) distribution systems for chip manufacturing, meeting Class 10 cleanroom standards with low particle shedding and high purity.
Water Treatment: Handles aggressive disinfectants like chlorine (up to 500 ppm) and ozone in municipal wastewater treatment plants and industrial water recycling systems.
HVAC Systems: Suitable for refrigerant lines (R-134a, R-410A) due to its low thermal conductivity (0.13 W/m·K) and freeze resistance, preventing ice blockages in cold environments.
FAQ
Q: Can this union tee be used with metal pipes?
A: Yes, the female flare connections are compatible with copper, stainless steel, and aluminum tubing when paired with appropriate metal flare adapters, ensuring reliable material compatibility.
Q: What welding method is recommended for installation?
