A403 WP304  eccentric reducer is a pipe fitting used to connect pipes of different diameters, and the central axes do not overlap, which means there is an eccentricity. The eccentric reducer has two ends, one with a larger diameter and the other with a smaller diameter. In terms of shape, it gradually transitions from the large diameter end to the small diameter end, and the shape of the transition part can be conical or curved. Due to the eccentric structure, the centers of the large and small diameters are not on the same straight line. It is mainly made of stainless steel, which has good corrosion resistance and high temperature resistance, and is suitable for pipeline systems in various special environments.
