常见问题

What is the primary function of an insulating sleeve in flange assemblies?

To prevent electrical current flow and heat transfer between metal flange surfaces, reducing risks of short circuits, equipment damage, and energy loss.

Consider operating temperature, chemical exposure, mechanical load, and required dielectric strength; silicone rubber is common for general use, while PTFE suits corrosive environments.

Can insulating sleeves be customized for specific applications?

Yes, sleeves can be tailored in dimensions, material composition, and reinforcement to match unique pressure, temperature, and electrical requirements.
