Describe the function and maintenance requirements of a 'surface rupture disc' in a geothermal steam system.

A surface rupture disc is a safety device used in a geothermal steam system to protect equipment from overpressure. It's a non-reclosing pressure relief device designed to burst at a predetermined pressure, providing a full and immediate release of steam to prevent catastrophic equipment failure. Its function is to act as a last line of defense. It's designed to rupture if the pressure in the system exceeds a safe limit, typically due to a malfunction or emergency situation. The rupture disc is installed in a specific location on the steam system, such as on a steam line or pres....
