Final answer:
An eccentric weld reducer is used to connect misaligned pipes of different diameters in a way that maintains level piping. A welded outlet, or weldolet, is a fitting that provides a reinforced connection between a branch pipe and a main pipe. Both are crucial components in maintaining effective and secure piping systems.
Step-by-step explanation:
An eccentric weld reducer is a type of pipe fitting used in piping systems to connect two pipes of different diameters that are not aligned along the same center line. Instead of being centered, an eccentric reducer has an edge that aligns with one side of the inlet and the outlet, thus allowing the fitting to maintain the top or bottom pipe level. Eccentric reducers are used in piping systems that require a smooth flow of fluid or gas without disturbance.
A welded outlet, also known as a 'weldolet', is a type of branching fitting. It provides an outlet from a larger pipe to a smaller one, or vice versa. The key feature of a weldolet is that it provides a means for a reinforced connection where the branch pipe is welded directly onto the run pipe, ensuring a strong and leak-proof joint that can handle changes in pressure or stress.
