What is the procedure for installing a water column on high pressure steam boiler?

To install a water column on a high-pressure steam boiler, first ensure that the boiler is shut down and depressurized. Then, locate the appropriate connection point, usually on the boiler's steam drum, and clean the surface to ensure a proper seal. Install the water column by securing it with appropriate fittings and ensuring all connections are tight to prevent leaks. Finally, connect the necessary gauge and ensure proper calibration before bringing the boiler back online.
