Stainless Steel Concentric Reducer
BW Concentric Reducer
Concentric Reducers are used to join pipe or tube sections of different diameters on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters.
Stainless Steel Eccentric Reducer
BW Eccentric Reducer
Stainless steel eccentric pipe reducer fitting is manufactured with the smaller outlet off center to the larger end, which allows it to align with only one side of the inlet.
Seamless Reducer
It is manufactured from seamless steel pipe, the manufacturing methods are hot and cold forming process. Usually the diameter is below 24 inch.
Weld Reducer
Weld reducers are manufactured from Welded Pipe with filler material (ERW & EFW pipes cannot be used to manufactured fittings). Large diameter fittings are manufactured from steel plate. The process is rolling the steel plate, then welding, forming by hot or cold.
Stainless Steel Pipe Reducer Weight
The weight chart of butt weld reducer is covering the size from 3/4 inch to 24 inch, and available in Schedule 20, STD, 40, 80, 120, 160.
