PTFE Moulded Expansion Bellows
Our PTFE Moulded Expansion Bellows are highly specialized flexible components within the Lined Pipe & Fittings category, designed to absorb and compensate for thermal expansion, vibration, and angular/lateral movement in aggressive chemical pipelines. Unlike lined components, these bellows are constructed entirely from pure PTFE, offering the ultimate level of chemical inertness and corrosion resistance across all wetted parts.
Superior Flexibility and Chemical Resistance
These bellows are moulded from high-grade PTFE, providing unmatched performance in dynamic applications:
- Material: Constructed from PURE PTFE (807/805), ensuring resistance to virtually all corrosive chemicals, solvents, and acids.
- Function: Essential for relieving stress on process equipment and piping systems caused by thermal cycling and mechanical movement.
- Size Range: Available in standard sizes from 25 NB to 250 NB.
- Flange Standard: Features durable IS 2062 steel flanges that adhere to ANSI B 16.5 and ASA 150# specifications, ensuring secure and compatible installation.
Guaranteed Integrity and Safety
Every PTFE Moulded Expansion Bellow is subjected to stringent quality control to ensure structural integrity and leak-proof performance:
| Test | Specification | Result |
| Hydro Test | $4.0 \, \text{kg/cm}^2$ | Confirms structural integrity and pressure capability. |
| Spark Test | $15 \, \text{KV DC}$ | Guarantees $100\%$ material non-porosity (critical for pure PTFE applications). |
| Dimentions | $100\%$ Visual Check | Ensures precise dimensional accuracy and flexibility. |
Choose our PTFE Moulded Expansion Bellows for a dependable, flexible, and completely corrosion-proof solution in your most demanding chemical transfer systems.
