Reducing joints, also known as different diameter pipes, are commonly known as small and small heads, and are one type of chemical pipe fittings for connection of two different pipe diameters.
1. Divided into two types: concentric reducer and eccentric reducer according to the appearance and use specifications.
2, according to the material classification of stainless steel (304, 304l, 316, 316l), alloy steel, carbon steel (20 #, Q235B, Q234, Q345) and so on.
3. According to the connection form, there are welded reducer joints, inner wire reducer joints, and outer wire reducer joints.Stainless steel reducer is one of the commonest stainless steel pipe fittings. Stainless reducer is the component in a pipeline that reduces the stainless pipe size from a larger to a smaller bore.
The length of the pipe reduction is usually equal to the average of the larger and smaller pipe diameters.
These reducers can be mainly divided into two types: concentric and eccentric stainless steel reducer.
The stainless steel reducers are usually concentric, while eccentric reducers are used when required to maintain the same top-or bottom-of-pipe level.
