A weld neck flange is a type of pipe flange that is welded to the neck of a pipe. The main purpose of a weld neck flange is to provide extra support to the pipe at the point where it joins the fitting. Weld neck flanges are often used in high-pressure applications, such as in hydraulic systems. They are also commonly used in applications where vibration or a thermal expansion could cause the pipe to come loose from the fitting. In addition to providing extra support, weld neck flanges also help to distribute stresses more evenly throughout the pipe, which can help to extend its lifespan.
