An anchor chair is primarily used in relation to pipes and fittings to do what?

An anchor chair is primarily used to support pipes by providing a stable base that helps maintain the alignment and positioning of the piping system. When pipes are installed, they can be subjected to various forces from factors like weight, temperature changes, and fluid flow. The anchor chair helps to resist these forces, preventing the pipes from moving out of their intended position, which is crucial for ensuring the integrity and functionality of the entire piping system.

By properly supporting the pipes at specific intervals, the anchor chair also helps distribute the load evenly and reduce stress on the pipe fittings and joints. This is particularly important in high-pressure systems where improper support could lead to leaks or failures over time.
