High Purity Flange
The High Purity Flange is a precision-engineered component designed to create a secure, contamination-free connection between pipes, valves, or equipment in ultra-clean piping systems. Manufactured from high-purity materials such as PFA, PVDF, or PTFE, the flange provides excellent chemical resistance and high thermal stability. It is used in critical fluid handling applications where reliability, cleanliness, and compliance with purity standards are essential.
Key Features of High Purity Flange
- High-Purity Material Construction: Made from ultra-clean PFA, PVDF, or PTFE to prevent contamination.
- Reliable Sealing Surface: Ensures leak-proof, vibration-resistant connections with compatible flange systems.
- Superior Chemical Compatibility: Resistant to corrosive acids, bases, and solvents.
- Thermal Durability: Maintains mechanical integrity under elevated temperature conditions.
- Smooth Internal Finish: Supports laminar flow and reduces the risk of particle shedding.
- Versatile Design: Compatible with stub ends, blind flanges, reducers, and other high-purity components.
- Cleanroom Manufactured: Produced under ISO Class 100 or better cleanroom conditions.
- Standards Compliant: Meets SEMI F57, FDA, and USP Class VI specifications.
