What does LWT stand for in the context of piping?

In the context of piping, LWT stands for Lateral Welded Tee. This term refers to a specific type of pipe fitting that is designed to connect a branch line to the main pipeline in a lateral position. The lateral welded tee is used to create a change in direction while facilitating the branch connection, allowing for efficient fluid transport within various piping systems.

The terminology is critical in engineering and construction, as different fittings serve specific functions, and proper identification ensures that the correct component is used for each installation. Understanding the specific characteristics of a lateral welded tee aids in various applications, from residential plumbing to large-scale industrial systems.
