What is a Concentric Reducer and Stainless Steel 321

Concentric reducer is designed to connect two parts of tubes or pipes of different sizes when they are on the same center axis in the pipe line. For example, a Stainless steel 321 concentric reducer will be applied when a 1/2 inch pipe is going to transit into an 1 inch pipe end meanwhile the two ends of the pipes don’t need to keep in the same level. The Concentric Reducer can be made from different kind of materials including carbon steel, alloy steel and stainless steel depending on the whole pipeline.

Stainless steel 321 concentric reducer is made of material stainless steel 321. Stainless steel 321, also known as 0Cr18Ni9Ti321 is special because it contains the elements titanium , and Ti has a very good function in intergranular corrosion test, so stainless steel 321 has a good corrosion resistance and good performance in low-temperature environment. Also stainless steel 321 has a good tolerance in the oxidizing acid such as nitric acid.

Concentric Reducer Specification

Stainless steel 321 concentric reducer belongs to the butt welding fitting which include in manufacturing standard AMSE B16.9.

Weight List of Concentric Reducer

Stainless steel 321 reducer is made from stainless steel, so the thickness schedule of it will be different from the chart, but the weight will be same as the similar schedule, like 40s similar to 40.

Test of Stainless Steel 321 Reducer

We will measure the outer diameter, inside diameter, thickness, and height of the Stainless steel 321 reducer. If you need, we could also have test of eccentricity ratio.

For material test, we will have a visual result of PMI test and save it for the record, and the impact test and other test can be proceeded under the requirement from your side.

All these test we will save the test record for your reference.
