For high pressure boilers with more than 100 square feet of heating surface, the feed connection shall not be smaller than which pipe size?

For high pressure boilers with more than 100 square feet of heating surface, the requirement for the feed connection is critical to ensure proper operation and efficiency. The correct pipe size of 3/4 inch is established to accommodate the necessary flow rates required for these systems.

The feedwater system plays a vital role in maintaining water levels and providing enough water to generate steam. If the feed connection is too small, it could lead to inadequate water supply, resulting in reduced efficiency and potentially dangerous situations such as boiler overheating or failure to maintain pressure.

Using a 3/4 inch feed line allows for sufficient water flow to meet the demands of larger high pressure boilers. This size effectively balances the need to supply adequate water while maintaining proper pressure levels within the system. Therefore, adhering to this standard is essential for the safety and functionality of high pressure boiler systems.
