What is the maximum permissible working pressure for a low-pressure steam boiler in Maryland?

The maximum permissible working pressure for a low-pressure steam boiler in Maryland is indeed 15 psi. This classification is vital for the safe operation and regulation of boilers. Low-pressure steam systems, typically used in heating applications, operate at pressures below this threshold, ensuring that the equipment is less likely to produce dangerous conditions compared to higher pressure systems.

Setting the limit at 15 psi helps ensure that safety measures are appropriate for the potential risks involved. Steam boilers above this pressure would require different regulations and would be classified as high-pressure steam boilers, which involve more stringent safety and operational standards. Thus, knowing and adhering to this limit is essential for anyone involved in the operation, maintenance, or inspection of boilers within the state of Maryland.
