Stainless steel elbow is the most important butt weld pipe fittings, they are fabricated by seamless stainless steel pipes or steel plate and get beveled end for butt-welding.
A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.
This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.
