What are boiler fittings?

Boiler fittings are essential components that are directly attached to the pressure parts of a boiler. These fittings serve multiple critical functions, including enabling safe operation, monitoring, and controlling the various parameters within a boiler system. Some common examples of boiler fittings include safety valves, pressure gauges, water level indicators, and blow-off valves.

These devices are integral to ensuring that the boiler operates efficiently and safely by providing necessary information and control, thus preventing conditions that could lead to boiler failure or accidents. Their placement directly on the pressure parts is crucial because it allows for accurate readings and immediate response to changes in the internal environment of the boiler, maintaining the integrity and performance of the system.

Other options, while relevant to the boiler system, pertain to aspects of boiler operation or auxiliary systems rather than the fittings themselves. Fuel storage, pressure regulation devices that are not fittings, and water treatment systems are all important in the context of boiler operations but do not fall under the classification of boiler fittings as understood in engineering practice.
