Detailed information and applications of the eccentric reducer
The eccentric reducer is an accessory that helps connect two stainless steel pipes with different diameters.
Because it is an accessory, the eccentric reducer will be applied in any industry where stainless steel pipes are used such as: factories, industrial parks, high-rise buildings,…
Standard table of parameters and sizes of eccentric reducer
Although different in design, the eccentric reducer and the concentric reducer have the same size standards.
