The processing methods of Stainless Steel Concentric & Eccentric Reducer are basically based on pressing, but the pressing process will increase the hardness and density of the steel. However, if it is not heated, it will easily cause cracks. Processing methods of large and small heads: Control of the diameter range. Generally, the processing range of large and small heads is within the first level. For example, the large and small heads of 325-159 basically need to be heated several times. The first choice is to cut the 325 pipe to the appropriate length, and then press the 325 diameter into 273. This pressing also needs to be heated. The second diameter change is the process of 273 changing to 219. This time, the pipe needs to be heated to the specified temperature and then pressed.

The last is the process of changing from 219 to 159. Each diameter change needs to be heat treated. Processing methods of large and small heads: Various materials have their own hardness and tensile strength characteristics, so the pressing strength of each material is different. For the same model of reducers, the processing methods and procedures will vary greatly depending on the material. For example, ordinary carbon steel reducers can be formed after three heat treatments. However, for reducers made of alloy materials, the greater the hardness, the more times of pressing and heating are required, and the more complicated the forming process is.
