What is the maximum static pressure limit in a fuel oil line before the oil pump, as regulated by code?

The correct answer is based on the regulations governing fuel oil systems. According to these codes, the maximum static pressure limit in a fuel oil line before the oil pump is established to ensure safe and efficient operation of the system. A static pressure of 35 kPa is specified because it maintains the integrity of the fuel oil delivery system while preventing undue stress on components and ensuring proper fuel flow. This limit is designed to avoid issues such as leakage or potential equipment failure due to excessive pressure.

The selected pressure is also within a range that allows for adequate performance of the pump without exceeding the material limits of the piping or fittings. In industry practices, too high pressures can lead to safety hazards and increased wear on mechanical systems.

Understanding the importance of maintaining this pressure within regulatory standards is crucial for safety, efficiency, and the longevity of the fuel oil system.
