Application Scope

Stainless steel butt welded elbows are a very important component in pipeline systems. They can not only connect pipelines, but also change the flow direction of pipelines, reduce fluid resistance, and regulate flow rates. Therefore, they are widely used in industries such as chemical, food, petroleum, natural gas, and biopharmaceuticals.
