A pressure vessel sight glass is a transparent window or viewport that is installed on a pressure vessel to allow visual inspection of the contents inside. It is typically made of a strong and durable material, such as tempered glass or polycarbonate, that can withstand the pressure and temperature conditions of the vessel.

The sight glass is usually mounted on a flange or welded directly onto the pressure vessel, and it is designed to provide a clear view of the interior without compromising the structural integrity of the vessel. It allows operators or inspectors to visually monitor the level, color, and condition of the contents, such as liquids or gases, inside the vessel.

Pressure vessel sight glasses are commonly used in various industries, including chemical processing, oil and gas, pharmaceuticals, food and beverage, and power generation. They are essential for ensuring the safe and efficient operation of the pressure vessel by allowing operators to detect any abnormalities or potential issues that may require attention or maintenance.
