An annual survey consists of the removal and dismantling of the first isolating valves from the boiler for inspection by an inspecting person.
The valves associated with this statement are;
  • Main Stop and non-return valves
  • Blow-down valve

  • Feed Water isolating and non-return valves
  • Pressure isolating valve
  • Level control valves
  • Gauge glasses

The boiler also requires an internal inspection on the water side and the fire side. The combustion and feed-water systems also require an inspection.
Each boiler has a certified pressure gauge that requires re-certification annually.
