FAQ

Q1: What is the main purpose of a single rubber bellows with a flexible connector?
A: It absorbs vibration, reduces noise, and compensates for thermal expansion or misalignment in the pipe.

Q2: Can chemically resistant materials be customized?
A: Yes. We offer natural rubber (NR) for domestic water, ethylene propylene diene monomer (EPDM) for acid and alkali resistance, nitrile rubber (NBR) for oil resistance, and fluororubber (Viton) for high-temperature resistance.

Q3: How do I choose the right size?
A: Please provide your pipe diameter, operating pressure, temperature, and media. Our technical team will recommend the appropriate specifications.

Q4: What is the average service life?
A: Typically 5-10 years, depending on operating conditions and maintenance.
