What is the difference between upright and pendent sprinklers

Upright and pendant sprinklers are two types of fire sprinklers that are commonly used in buildings to protect against fires. While both types of sprinklers operate in a similar way, there are some significant differences between them. In this article, we will discuss the differences between upright and pendant sprinklers.

Upright Sprinklers

Upright sprinklers are mounted in an upright position and are typically used in areas where the ceiling is not accessible, such as in storage rooms and warehouses. They are also used in areas where the temperature may be higher, such as near ovens and furnaces. Upright sprinklers are designed with a deflective plate that directs the flow of water into a specific pattern, which spreads out in a circular shape. The water is then distributed over the surrounding area, effectively extinguishing the fire.

One of the advantages of using an upright sprinkler is that it is easy to install and can be installed in tight spaces. The sprinkler head is mounted on a pipe that is attached to a fitting, which is mounted onto a horizontal branch line on the ceiling. Upright sprinklers are also effective at extinguishing fires quickly, as they are activated by the heat of the fire and can release water directly onto the source of the fire.

Pendant Sprinklers

Pendant sprinklers are mounted on the ceiling in an upside-down position and are commonly used in areas where the ceiling is accessible, such as in offices, retail spaces, and other types of commercial buildings. They are designed to distribute water in a specific pattern, which is typically a large, circular shape. The water is then distributed over the surrounding area, effectively extinguishing the fire.

One of the advantages of using a pendant sprinkler is that it is less noticeable than an upright sprinkler and can blend in with the surrounding ceiling. Pendant sprinklers are also easy to install and can be mounted onto a drop or suspended ceiling. They are also effective at extinguishing fires quickly and can be activated by the heat of the fire.

Differences between Upright and Pendant Sprinklers

There are several differences between upright and pendant sprinklers. The first difference is the mounting position. Upright sprinklers are mounted in an upright position, while pendant sprinklers are mounted on the ceiling in an upside-down position. The second difference is the application. Upright sprinklers are commonly used in areas where the ceiling is not accessible, while pendant sprinklers are commonly used in areas where the ceiling is accessible. The third difference is the water distribution pattern. Upright sprinklers distribute water in a circular pattern, while pendant sprinklers distribute water in a large, circular shape.

In conclusion, both upright and pendant sprinklers are effective at extinguishing fires and protecting against property damage. The selection between the two types of sprinklers is based on the application, mounting position, and water distribution pattern. It is important to have a professional fire protection company assess your building's fire protection needs and install the appropriate type of sprinkler system to protect against fire damage.
