High Purity Stub End Flange
The High Purity Stub End Flange is a precision-formed fitting designed to provide a secure and clean connection between high-purity piping and flanged components. It consists of a short pipe piece (stub end) that is used with a loose backing flange, enabling easy disassembly and alignment without rotation of the pipe. Manufactured using ultra-pure materials like PFA, PVDF, or PTFE, this fitting is ideal for critical process systems that demand leak-proof connections, superior chemical resistance, and contamination-free performance.
Key Features of High Purity Stub End Flange
- Ultra-Pure Material Composition: Available in PFA, PVDF, or PTFE to maintain purity in critical fluid systems.
- Disassemblable Design: Allows for easy removal, inspection, and maintenance of flange joints.
- Corrosion & Chemical Resistance: Inert to most acids, bases, and solvents.
- Leak-Free Integration: Works with compatible flanges to ensure a tight, reliable seal.
- High-Temperature Tolerance: Suitable for demanding thermal process conditions.
- Smooth Surface Finish: Minimizes particle generation and supports laminar flow.
- Cleanroom Fabrication: Manufactured in ISO Class 100 or better conditions.
- Compliant with Industry Standards: Suitable for use in SEMI, FDA, and USP Class VI regulated systems.
