Why is the sealing gasket important to glass-lined equipment?

The general purpose of the gasket is to prevent leakage, but for glass-lined equipment, the purpose is more than this:
The gasket can also protect the integrity of the glass-lined vessel and reactor. Incorrect selection of gaskets or improper torque maintenance may damage the glass-lined container.
A small leak of highly corrosive media at the nozzle or manhole, leaking to the flange surface, may damage the glass at the edge of the flange, that is, the end of the glass.
This may cause the glass layer to break, damage the glass on the flange surface, and then damage the container itself, resulting in the need to repair all the glass.

What are the requirements for gaskets for glass-lined systems?

D-7590 gasket meets the following requirements:

Convenient and safe on-site installation and operation
High compressibility, compensating for unevenness of flange glass surface

Suitable for glass-lined surfaces with low surface pressure. Perfect sealing of all glass-lined nozzles
Provides compression safety compensation under different pressures and temperatures in the container, that is, the residual elasticity after tightening

Under design conditions, it has the same chemical resistance as glass-lined containers
Provides dimensional stability even with large diameters
