Production Description

A MSS SP 43 Stainless Steel A403 WP304L Butt Weld Fitting Concentric Reducer Mnufacture is a component used in the pipelines to reduce its size from large to small bore in accordance to the inner diameter. The length of the reduction here is equal to an average of the smaller and larger pipe diameters. Here, the reducer can be used as a diffuser or a nozzle. There are two types of reducer, concentric reducer and eccentric reducer. A reducer allows for a change in pipe size to meet hydraulic flow requirements of the system, or to adapt to existing piping of a different size. A MSS SP 43 Stainless Steel A403 WP304L Butt Weld Fitting Concentric Reducer is the first one.

Material

MSS SP 43 Stainless Steel A403 WP304L Butt Weld Fitting Concentric Reducer mean the pipe fittings which material is wrought austenitic stainless grade WP304L,they are used for the pressure piping systems of moderate and high temperature services.ASTM A403 is the standard of pipe fittings material,it indicates the materials properties of different kinds of stainless steel,WP304L is one of the steel grade in this standard.The corrosion resistance of 304L and 304 are similar.But after eliminate stress or welding,corrosion resistance of 304L will be more excellent.ASTM A403 WP304L is the most common stainless steel pipe fittings material.
