However, taking specific pipeline systems such as stair handrails, building internal and external wall handrails, corridor railings, etc. as examples, the existing 90-degree stainless steel elbow connectors generally adopt direct welding, threaded fixing and other methods. These methods require a lot of manpower and material resources during the installation process. Because there is no socket-type straight round pipe section structure at its end, it cannot be used for the socket-type fixing method when the inner socket is inserted into the pipeline. The socket-type metal elbow not only solves the above problems, but also the first socket-type metal elbow also avoids the need to cut a semicircular opening when installing with a vertical pipe column, which is troublesome, labor-intensive, time-consuming, and not accurate and beautiful. The support plate structure of the other socket-type metal elbow makes it easy to operate and beautiful in structure when welding with the wall. During the installation process, the existing elbow is also inconvenient in aligning the pipe port and adjusting the angle, and the work efficiency is low.
