PN16 Corrosion Resistant PPH Union Tees Pipe Connection

Product Overview

The PN16 Corrosion Resistant PPH Union Tees Pipe Connection is a high-performance piping component engineered for precise corrosive fluid handling in industrial systems. Crafted from high-purity polypropylene homopolymer (PPH) through advanced extrusion and injection molding processes, it delivers superior resistance to acids, alkalis, and organic solvents while maintaining structural integrity under sustained high pressure. The union design features a detachable middle section that allows for quick disassembly, inspection, and maintenance without cutting pipelines, making it ideal for critical applications in chemical processing, water treatment, and mining. With a pressure rating of PN16 (16 bar) at 20°C, this union tee ensures leak-free connections even in environments with frequent pressure fluctuations.

Features

Extreme Chemical Resistance: Undergoes rigorous testing to withstand 98% sulfuric acid, 50% sodium hydroxide, and chlorinated solvents (e.g., trichloroethylene) for 10,000+ hours without measurable weight loss or structural degradation, outperforming 316 stainless steel in chloride-rich environments.

High 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 rapid temperature cycles, preventing joint loosening or leakage in HVAC and industrial heating systems.

Heavy-Duty Construction: Maintains structural stability under 16 bar (232 psi) working pressure at 20°C, with a burst pressure exceeding 48 bar (696 psi) — three times the maximum operating pressure — for enhanced safety in high-pressure chemical transfer.

Easy Installation: Features socket fusion welding compatibility (EN ISO 10931) for permanent connections and mechanical union joints with EPDM gaskets for removable setups, reducing installation time by 30% compared to metal fittings that require specialized tools.

Longevity: Inherently resistant to UV radiation, oxidation, and microbial growth (e.g., biofilm formation), with an expected service life of 20+ years in continuous industrial operation, reducing lifecycle replacement costs by 50% versus PVC alternatives.

Applications

Chemical Processing: Transfers aggressive reagents (e.g., hydrochloric acid, caustic soda) in pharmaceutical batch reactors, petrochemical distillation units, and specialty chemical blending systems, ensuring process purity and equipment safety.

Water Treatment: Handles chlorine (up to 500 ppm) and ozone in municipal wastewater treatment plants, maintaining compliance with NSF/ANSI 61 standards for material safety in potable water applications.

Mining Industry: Used in slurry pipelines for transporting corrosive mineral slurries (e.g., copper sulfate, iron ore suspensions), with abrasion resistance that extends 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 and improve system efficiency.

FAQ

Q: Can this union tee be used with metal pipes?

A: Yes, it is fully compatible with metal tubing (steel, copper, aluminum) via threaded adapters (ISO 7-1) with PPH-to-metal transition joints, ensuring reliable material compatibility and preventing galvanic corrosion.

Q: What welding method is recommended for permanent installation?

A: Use socket fusion welding at 260°C ±5°C with proper cooling time (3-5 minutes for 2" diameter), following EN ISO 10931 guidelines to create seamless, leak-proof bonds that match the strength of the parent material.

Q: Does it comply with food-grade standards for beverage processing?

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 (e.g., cleaning agents, sanitizers) in breweries and bottling plants.
