An anchor chair is a type of pipe fitting used primarily in piping systems to provide structural support for piping and to help manage the forces generated by thermal expansion, contraction, and other stresses. Specifically, an anchor chair is designed to hold a pipe securely in place at a specific location, preventing movement that could lead to stress on joints and connections.
In applications where pipes are subjected to significant loads or where they need to be anchored to prevent vertical movement, anchor chairs serve to maintain the integrity of the piping system. They can also help in distributing the weight of the pipe, reducing the risk of sagging or bending, which can lead to damage over time. Anchor chairs are commonly utilized in heavy industrial applications, shipbuilding, and various mechanical systems requiring robust pipe support.
