Stainless reducer is a popular type of butt welded pipe fittings as stainless steel has better corrosion resistance and longer using period.Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd is an experienced manufacturer who supply butt weld fittings for years.

 

BW reducer has two types:Concentric and Eccentric

The two ends of concentric reducer are designed with large diameter and small diameter, and the pipe is connected through conical transition section on the same axis.

Eccentric reducers have different end sizes and are used to connect pipes with different diameters on the same axis.

 

ECC Reducer VS COC Reducer

  • The joint effect of the two is that the diameter change needs to change from one specification to another.
  • Concentric reducer is conducive to fluid flow, and the interference to fluid flow state is small when the diameter is reduced. Therefore, concentric reducers are used for gas and vertical flow liquid pipelines;
  • One side of the eccentric reducer is flat, which is convenient for exhaust or liquid discharge, startup and maintenance. Therefore, eccentric reducer is generally used for horizontal liquid pipeline.

 

The end of Butt welded fittings are connected to the pipe system by butt welding.Butt weld fittings provide permanent leak-proof performance.BW fittings could made from seamless or welded pipe,and then through several processes formed to get the shape of pipe fittings.
