Control valve station: An eccentric reducer with a flat side down is required to get a constant flow through the control valve with less flow disruptions.

Normally eccentric reducers with the flat side down are preferred for the following cases on horizontal lines: On the other hand, an eccentric reducer is a type of pipe reducer that has an asymmetrical centerline. It is designed to reduce the pipe’s diameter and shift the centerline of the pipe at the same time, which means that it is commonly used in vertical piping systems where there is a need to maintain a constant fluid level. With an eccentric reducer, the centerline of the larger end of the reducer is offset from the centerline of the smaller end, which means that the fluid flow direction changes.In summary, the main differences between concentric and eccentric reducers are their shapes and their application. A concentric reducer has a symmetrical centerline and is used to reduce the diameter of the pipe uniformly, while an eccentric reducer has an asymmetrical centerline and is used to shift the centerline of the pipe while reducing the diameter. Carbon Steel material standards and grades used for pipe reducers are ASTM A234 WPB, A420 WPL6, MSS-SP-75, etc While using an eccentric reducer, the user has the option of orienting the flat side. Usually, for horizontal lines, eccentric pipe reducers are oriented with either the flat side up or down, and the same with deviation is mentioned in isometric. Specific Uses of Eccentric Reducers In horizontal gas, steam, or vapor piping, eccentric reducers are required to be installed with a flat side down which allows condensed water or fluid to drain at low points. Pump Suction Piping Reducer Flexible Drainage Adaptors and Reducers offer a versatile solution for connecting pipes of different diameters. These special couplings are available in a variety of size ranges to suit most applications and are easy to install without the need for special tools or equipment.

Pipe reducers are made of various materials like Carbon Steel, Alloy, Stainless steel, and many more non-ferrous materials. As compared to the Stainless Steel Reducer, Carbon Steel Reducer possesses higher strength, high-pressure resistance, and wear resistance but this can be easily corroded.

Stainless Steel Pipe Reducer material grades are: ASTM A403 WP 304, 304L, A403, 316, 316L, 317, 317L, 321, 310 and 904L, etc. The common materials used for the construction of such pipe reducers are explained below. Materials of Pipe Reducers Please Note: Under current regulations, Flexible Adaptor Couplings and Reducers are prohibited for use on adopted drainage systems. Straight Connection couplings with a shear band should be used instead to ensure the connection is protected under earth loads. If a connection needs to be made between drainage pipes that have different outside diameters, combine a Shear Banded Coupling with a Flexseal Bush or Multibush. A concentric reducer and an eccentric reducer are two different types of pipe reducers that are used to connect pipes of different sizes. The main differences between them are in their shapes and how they are used. These simple yet effective connectors can be tightened onto pipes of different diameters using a nut driver and torque wrench, creating an airtight and watertight seal in just seconds. The robust design of Flexible rubber drainage adaptor couplings and reducers allows them to connect plastic drainage pipes to other drainage materials such as clay, concrete, stainless steel, cast iron and pitch fibre. This makes them suitable for use with both traditional and modern pipe systems.
