When tanks are heated by steam coils, the steam coils must not exceed what gauge pressure?

When tanks are heated by steam coils, the steam coils must not exceed 15 PSI gauge pressure to maintain safe operation. This specification is in accordance with safety standards designed to prevent excessive pressure build-up, which could lead to corrosion, damage to the tank structure, or even catastrophic failures. Limiting the pressure to 15 PSI helps ensure that the heating process is effective while still allowing for the safe expansion and contraction of the steam within the coils without compromising the integrity of the system.

In practical terms, using steam at pressures above this limit could pose risks such as leaks, ruptures, or other hazardous situations, which is why regulatory guidelines set this maximum threshold to effectively manage risk in heating applications involving steam coils. This understanding is critical for professionals in the field, emphasizing the importance of adhering to established safety standards and practices.
