What is important when inspecting tanks during a pressure test?

When inspecting tanks during a pressure test, it is crucial to soap the surfaces, seams, and fittings to check for bubbles. This method helps to detect any leaks in a tank by identifying where air is escaping, as bubbles will form at the site of a leak when soapy water is applied. This technique is essential for ensuring the integrity of the tank and confirming that it can safely hold pressure without any leaks, which is a critical aspect of maintaining safety and compliance with regulations.

Using soap for this inspection not only serves as an effective visual indicator of leaks but also helps to ensure that the pressure test is thorough, providing reassurance that the tank is functioning as intended before it is put back into service. This focus on sealing and leak detection is a best practice in tank maintenance and installation, ensuring long-term reliability and safety.
