ASTM A403 WP304 Stainless Steel 180 Degree Elbow B16.9 Buttweld Pipe Fittings
ASTM A403 / ASME SA403 WP304-S 180 Degree Elbow, Stainless Steel Buttweld Pipe Fitting
A 180 degree elbow is a type of pipe fitting used to create a change in direction in a piping system. It essentially turns the flow of material or fluid back in the opposite direction. According to different work environment and purpose, the material of elbow can be carbon steel, stainless steel, alloy steel, etc. They are commonly used in piping systems and are designed to change the direction of the piping by 180 degrees.
