Stainless Steel Eccentric Reducer

A stainless steel eccentric reducer is a type of pipe fitting that is used to connect two pipes of different diameters. This type of reducer is called eccentric because the center of the inlet and outlet of the reducer is not aligned. Instead, it is offset, resulting in one side of the reducer being larger than the other.

Stainless steel is a popular material for eccentric reducers because it is durable, corrosion-resistant, and can withstand high pressure and temperature. Stainless steel eccentric reducers are often used in industrial applications where the flow of fluids or gases needs to be controlled or redirected.

The benefits of using a stainless steel eccentric reducer include:

1. Corrosion resistance: Stainless steel is highly resistant to corrosion, making it ideal for use in harsh environments.

2. Durability: Stainless steel is a strong and durable material that can withstand high pressure and temperature, making it a reliable choice for industrial applications.

3. High temperature resistance: Stainless steel can withstand high temperature environments without losing its strength or durability.

4. Hygienic: Stainless steel is easy to clean and maintain, making it a hygienic choice for use in food processing and other sanitary applications.

In summary, a stainless steel eccentric reducer is a useful pipe fitting that is commonly used in industrial applications. Its durability, resistance to corrosion and high temperature, and hygienic properties make it a reliable choice for controlling the flow of fluids or gases in pipelines.

ASME B16.9 Butt Welding Eccentric Reducer Weight Calculator

Approximate weight of a Butt welding Eccentric Reducer are calculated supported its header length, header size, branch size, branch length, header wall thickness and branch wall thickness. Please note that actual weight of a tee from a particular manufacturer might vary counting on manufacturing methodology. Dimensional standards like ASME B16.9 do not supply weights of butt attachment fittings.

Weight of a Butt Weld Eccentric Reducer as per ASME B16.9 is calculated as per following formula :

0.02466 * S <(D+d)/2 – S> * H / 1000

W = Weight in Kg

OD1 = Large Size Outside Diameter (mm)

OD2 = Smaller Size Outside Diameter (mm)

t = Wall Thickness (mm)

H = End to End Dimension (mm)
