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. Reducers are usually concentric but eccentric
reducers are used when required to maintain the same top- or
An Eccentric Reducer, also called a Bell reducer, has two female (inside) threads of
different sizes with centers so designed that when they are joined,
the two pieces of pipe are not in line with each other, but they
can be installed so as to provide optimum drainage of the line.
Eccentric Reducers eliminate noise and isolate vibration in the
pipeline, reduces stress, eliminates electrolysis and protects
against start-up surges.
A Concentric Reducer joins the tube sections on the same axis. They connect unequal
size pipes that have a common centerline and are used for TC
transitions in vertical tubing.
A Concentric Reducer has different size ends to mate hose or tubing
of different diameter that joins tube sections on the same axis.
Since virtually all piping systems go through changes in diameter
either in the run or at the equipment connections, a reducer serves
the dual purpose of changing the piping diameter and at the same
time that of handling the expansion, misalignment or vibration
Material: the material of the reducer can be made in ASTM(WPB, WPC,
WPL6,WPL3, WP1, WP12, WP11, WP5, WP9, WP304, WP304H, WP310, WP316,
WP347, WP321H, WP347H), DIN,JIS
Size: the size of the reducer can be made in 1/2'' ~72''
(DN15~1800), Wall thickness: SCH5(S) - SCH160(S)
Standard: the standard of the reducer ASME/ANSI B16.9 B16.28
