Changing the seal type on a top-notch water heater

Changing the seal type on a top-notch water heater

Original Condition

At the flange joint of the high-performance water heater, repeated leaks occurred during the shutdown and startup of the boiler. An analysis of the current condition revealed that a fiber-rubber gasket was used, which is not a suitable material for the specified temperatures.

Operating Parameters:

  • Temperature: 300 °C
  • Pressure Test: 3.1 MPa
  • Medium: steam

Solution

Based on the analysis, a change in the sealing material was proposed. The original fiber-rubber seal was replaced with metal sealing with a high degree of resilience. At the same time, the dimensions of the seal were optimized based on calculations.
