The XITA PPH All-plastic Loose Flange is engineered to deliver a secure, corrosion-resistant connection for aggressive industrial piping systems. Unlike standard metal backing flanges, this all-plastic solution eliminates galvanic corrosion risks and ensures long-term integrity in harsh acid/alkali environments.
Combining a precision-molded, chemically inert PPH body with a reinforced, stress-free rotational design, it guarantees leak-proof sealing and easy alignment during installation. It is the ideal choice for chemical processing, semiconductor facilities, and wastewater treatment systems requiring reliable, maintenance-free flange connections with full corrosion protection.
Key Features & Technical Advantages
✔Exceptional Chemical Resilience: Engineered with industrial-grade PPH (Polypropylene Homopolymer), the All-plastic Loose Flange provides superior resistance to strong acids, alkalis, oxidizers, and solvents, ensuring durable protection at critical connection points in corrosive pipeline systems.
✔High Purity & Zero Contamination: Crafted from inert, smooth-surface PPH material, it eliminates scaling, leaching, and external contamination, making it suitable for high-purity flange connections in semiconductor, pharmaceutical, and clean process applications.
✔Reliable Leak-Proof Seal: Featuring a precision-molded design with integrated sealing surface and rotational loose flange, it ensures a robust, pressure-resistant, and leak-free connection even under thermal cycling and system pressure fluctuations.
✔Structural Integrity Under Stress: Designed to maintain dimensional stability and sealing performance at flange joints under continuous thermal exposure and mechanical load, eliminating galvanic corrosion risks associated with metal backing flanges.
✔Lifecycle Value Advantage: While the initial cost may exceed standard metal flanges, its maintenance-free performance, corrosion resistance, and extended service life deliver measurable long-term savings in demanding corrosive and high-purity piping systems.

FAQ
Q: How do you protect the actuator from acid fumes?
A: We utilize a double-sealing structure (O-rings + PTFE seat) to strictly isolate the medium, preventing corrosive vapors from entering the actuator housing.
Q: Can I integrate this valve with my PLC system?
A: Yes. Our valves come with standard wiring diagrams and support feedback signals, making integration into automated PLC systems seamless.
Q: What is the cycle life of the electric actuator?
A: The actuator is designed for high-frequency use, tested for over 50,000 cycles under rated load conditions.
