Butt welded elbows are widely used in most project to change the direction of pipeline system. They shall be welded to pipes. So the both ends are machined to bevel ends. In many cases, different angles of elbows are needed, such as 45deg, 60deg, 90deg, 180deg and so on. Cause all the bend radius are not same, there are long radius and short radius elbows. Usually manufacture materials are carbon steel, alloy steel, stainless steel, aluminum, cooper. In our factory, you can see a lot of black pipe elbows. They are painted by customers` requests. On the way of transportation, painting will prevent rusting.
