Create inspection rooms
The fuel tank inspection chamber is created in the event that it is not present during excavation. It is the chamber through which the inspection hole is entered.
The inspection room at a gas station is an important part of the station's infrastructure, used to monitor and maintain the various systems operating within the station. This room is typically located underground and contains several key components:
1- Fuel Pipes: Pass through the inspection chamber to transport fuel from the tanks to the distribution pumps. 2- Valves: Used to control fuel flow through the pipes.
3- Sensors: Monitor fuel levels, pressure, and temperature, and send data to the monitoring system.
4- Safety Systems: Include leak detectors and fire extinguishers.
5- Electricity and Cables: Provide power to the various systems in the station.
The inspection chamber is a sensitive area due to the presence of flammable fuels and gases. Therefore, it must be equipped with adequate ventilation and advanced safety systems to prevent accidents. It must also undergo periodic inspections to ensure the integrity of the systems and to ensure the absence of leaks or malfunctions.
Gas station workers must strictly follow safety procedures when entering the inspection room, such as wearing personal protective equipment and using gas measuring devices to ensure that there are no toxic or flammable gases.

Pressure testing of the lines connecting the tanks and pumps
Inspecting petroleum pipelines using air pressure is a common method for ensuring the integrity of the pipelines and the absence of leaks or defects. This process is known as hydrostatic testing or pneumatic testing, and the choice between them depends on the nature of the pipelines and the surrounding conditions.
Purpose of the test:
• Ensure there are no leaks in the pipes.
• Check the pipes' ability to withstand operating pressures.
• Detect any defects in the welds or materials used.
Steps for inspecting pipes using air pressure:
• Pipe preparation: Thoroughly clean the pipes and remove any debris or obstructions.
• Seal the ends: The two ends of the pipe are tightly sealed using caps or flanges to prevent air leakage.
• Connect the air pump: An air pump is connected to an opening in the pipe to pump air into it.
• Increase the pressure: The air pressure is gradually increased until the desired test pressure is reached.
• Monitor: The pressure is monitored for a specified period of time (usually 10-30 minutes) to ensure it remains stable and there is no pressure drop.
• Leak Detection: Liquid soap or a leak detection solution is used on welds and joints to detect any air bubbles that indicate leaks.
• Recording Results: Results are recorded and documented to ensure the integrity of the pipes.
Pressure Standards:
• Test Pressure: The test pressure is determined based on industry standards and the pipe type. Typically, the test pressure is 1.5 to 2 times higher than the operating pressure.
• Operating Pressure: The pressure at which the pipe operates during normal operation.
Tools Used:
• High-pressure air pump.
• Pressure gauge to monitor pressure.
• Liquid soap or leak detection solution.
• Caps or flanges to seal the ends.
Challenges:
• Explosion risk: Pneumatic pressure testing carries the risk of explosion due to the energy of compressed air, so it must be handled with care.
• Accuracy: Equipment must be precise to ensure reliable results.
• Hydrostatic testing: Water or other liquids are used to increase pressure inside pipes. It is considered safer because, in the event of a rupture, less energy is released compared to compressed air.
• Pneumatic testing: Air or gases are used in specific situations where water cannot be used, such as pipes that must be kept dry.
Conclusion:
Petroleum pipeline inspection using air pressure is a delicate process that requires high precision and adherence to strict safety procedures. It must be performed by specialists using appropriate equipment to ensure the integrity and effectiveness of the pipelines in transporting oil or gas.
