- **Caution**: 

### Q: What is the primary function of an anti-telescoping device in RO membrane systems?
**A**: The anti-telescoping device prevents axial movement (telescoping) of membrane elements under high pressure, maintaining structural integrity and preventing damage to the membrane sheets and spacers.

### Q: Which materials are best suited for anti-telescoping devices in corrosive environments?
**A**: For corrosive environments, stainless steel (particularly 316L grade) and fiber-reinforced composites offer excellent corrosion resistance, while engineering plastics like ABS and polypropylene provide chemical resistance at lower pressures.

### Q: How does the anti-telescoping device integrate with RO membrane elements?
**A**: The device typically consists of a main body ring that fits around the membrane element, with retention features that engage with the element housing and a sealing surface that prevents bypass flow, ensuring proper pressure distribution.
