Which type of spring support maintains a constant load regardless of the pipe's position?

The type of spring support that maintains a constant load regardless of the pipe's position is known as a constant spring support. This design is specifically engineered to provide a consistent load to the piping system throughout its range of motion.

A constant spring support functions by utilizing a mechanism that allows the spring to compress or extend without changing the overall force exerted on the pipe. This is particularly important in applications where the pipe may experience thermal expansion or contraction, or when it may move due to external forces. By maintaining a constant load, the spring support helps in preventing undue stress on the piping components, thereby enhancing the system's reliability and longevity.

In contrast, other types of spring supports, such as variable or non-constant supports, do not provide this level of load consistency, leading to varying forces that could affect the performance and integrity of the piping system under different conditions.
