Our chemicals are suitable for land, marine and heritage steam boilers. A badly treated steam boiler is a potential bomb, so getting the feed water quality and boiler water chemistry correct is critical and that means using tried and tested boiler water treatment chemicals.
The intent of the boiler-code requirement is to be able to flow feedwater into the boiler as fast as the boiler reliefs can dump steam, thereby preventing a high-pressure condition from cascading into a dangerous low-water casualty. Are all relief valves in the feedwater system coordinated to fit into this scheme? Test connections.
