Product Overview
Manufactured from high-purity PPH resin through precision machining, it offers exceptional resistance to concentrated acids, oxidizing agents, and organic solvents. With a pressure rating of PN16 (16 bar) and a wide temperature range of -20°C to 100°C, this hybrid fitting combines a 1/4-inch flared end for threaded connections with a DN15 socket end for welding, providing unmatched flexibility in pipeline configurations. It ensures reliable performance in chemical processing, semiconductor manufacturing, and power generation applications.
Features
Extreme Chemical Immunity: Undergoes accelerated aging tests to withstand hydrofluoric acid (40%), sodium hypochlorite (15%), and aromatic hydrocarbons (benzene, toluene), outperforming PTFE in high-stress applications due to superior mechanical strength.
Precision Engineering: Features a 37° sealing angle for leak-free threaded connections and a smooth inner surface (Ra ≤0.8μm) that minimizes fluid friction, reducing pressure loss by 15% compared to threaded metal fittings.
Wide Temperature Range: Maintains dimensional stability from -40°C (cryogenic storage) to 100°C (high-temperature reactors), with minimal thermal expansion that prevents joint stress during rapid temperature cycles.
Certified Compliance: Meets ISO 15494 standards for thermoplastic piping systems and ASME BPE requirements for bioprocessing equipment, ensuring compatibility with ultra-pure water systems in Class 10 semiconductor cleanrooms.
High Mechanical Strength: Boasts tensile strength ≥53MPa and compressive strength ≥13MPa, resisting pipeline vibrations, pressure surges, and external mechanical impacts common in industrial settings.
Applications
Petrochemical Industry: Facilitates the transfer of benzene, xylene, and other aromatic solvents in refinery distillation units and petrochemical storage facilities, preventing corrosion-induced leaks that could lead to environmental hazards.
Semiconductor Manufacturing: Integrates into ultra-pure water (UPW) systems for chip production, where its low particle shedding and high purity (≤0.1% extractables) meet Class 10 cleanroom standards for contamination control.
Power Generation: Handles cooling water with high chloride content (up to 10,000 ppm) in thermal power plants, outperforming copper-nickel alloys by resisting chloride-induced stress corrosion cracking.
Solar Energy: Integrates into solar panel cleaning systems, resisting UV-induced degradation and maintaining integrity during frequent exposure to deionized water and cleaning agents (citric acid solutions).
FAQ
Q: What is the maximum pressure at 80°C?
A: Due to PPH’s temperature-pressure derating characteristics, the maximum operating pressure decreases to 12 bar at 80°C. This rating is still sufficient for most high-temperature chemical transfer applications in industrial settings.
Q: Can it be used in saltwater environments?
A: Yes, its inherent chemical resistance makes it ideal for saltwater applications, as it resists chloride-induced stress corrosion cracking (SCC) — a common failure mode in stainless steel fittings exposed to marine environments.
Q: What welding method is recommended for DN15 socket?
A: Butt fusion welding following ISO 15494 standards is recommended for the DN15 socket end. This method uses a heated plate to create a uniform fusion zone, ensuring the joint strength matches the pipe’s inherent strength for reliable performance.
