1/2 Inch PPH Flared Connector for Pipes

Product Overview

Crafted from high-purity polypropylene homopolymer (PPH) through advanced injection molding, it delivers superior resistance to acids, alkalis, and organic solvents while maintaining structural integrity under moderate pressure conditions. The flared design features a precision-machined 37° sealing surface that creates a tight, leak-free seal when paired with compatible flare nuts, allowing for quick and secure connections with PPH pipes. This connector is ideal for chemical processing, water treatment, and mining applications, where reliable fluid transfer is critical. With a pressure rating of PN10 (10 bar) at 20°C, it ensures consistent performance in demanding operational environments.

Features

Extreme Chemical Resistance: Undergoes rigorous testing to withstand prolonged exposure to concentrated sulfuric acid (98%), sodium hydroxide (50%), and chlorinated solvents (methylene chloride, trichloroethylene), outperforming 304 stainless steel in chloride-rich environments by resisting pitting and corrosion.

Temperature Stability: Operates reliably from -20°C to 100°C, with a low thermal expansion coefficient (≤100×10⁻⁶/°C) that minimizes dimensional changes during temperature fluctuations, preventing joint loosening or leakage.

Heavy-Duty Construction: Maintains structural stability under 10 bar (145 psi) working pressure at 20°C, with a burst pressure exceeding 30 bar (435 psi) — three times the maximum operating pressure — for enhanced safety in high-stress applications.

Easy Installation: Features a flared socket design with guided alignment markers, reducing installation time by 30% compared to metal fittings. Compatible with standard PPH pipes (OD 16mm) without requiring specialized tools.

Longevity: Inherently resistant to UV radiation, oxidation, and microbial growth (bacteria, fungi), with an expected service life of 20+ years in continuous industrial operation, reducing maintenance and replacement costs.

Applications

Chemical Processing: Facilitates the transfer of aggressive reagents such as pharmaceutical intermediates, petrochemical distillation by-products, and specialty chemical blends in batch reactors and continuous flow systems.

Water Treatment: Handles chlorine (up to 500 ppm), ozone, and pH-adjusting chemicals in municipal wastewater treatment plants and industrial water recycling systems, ensuring compliance with NSF/ANSI 61 standards for material safety.

Mining Industry: Integrates into slurry pipelines for transporting corrosive mineral slurries (copper sulfate, iron chloride) from extraction sites to processing facilities, extending equipment lifespan by 3-5 years compared to rubber-lined steel pipes.

HVAC Systems: Suitable for hot water distribution (up to 80°C) in commercial buildings, leveraging low thermal conductivity (0.22 W/m·K) to reduce energy loss through pipe walls and maintain consistent fluid temperatures.

FAQ

Q: Can this connector be used with metal pipes?

A: Yes, it is fully compatible with metal tubing (copper, galvanized steel) via threaded adapters conforming to ISO 7-1 standards. The adapter creates a transitional seal between PPH and metal, preventing galvanic corrosion.

Q: What welding method is recommended?

A: For permanent connections, use socket fusion welding at 260°C ±5°C, following EN ISO 15494 guidelines. The process creates a molecular bond between the connector and pipe, ensuring a seamless, leak-free joint.

Q: Does it comply with food-grade standards?

A: While not FDA-approved for direct food contact, it meets DIN 8078/8077 standards for potable water systems, making it suitable for non-food-grade chemical applications in beverage processing plants (e.g., cleaning agent distribution).
