Stainless steel reducers heat treatment technology

　　In the process of shrinkage or expansion deformation and pressing of stainless steel reducers pipe fittings, cold or hot pressing is adopted according to the different materials and A403 Seamless WP 321 Concentric Pipe Stainless Steel Reducer.Usually, cold pressing is adopted as far as possible, but in the case of severe processing hardening caused by multiple diameter changes, hot pressing is preferred for thick wall or alloy steel. The tube blank smaller than the big end diameter of the big head is formed by expanding along the inner diameter of the tube blank with an internal punch.

　　The tonnage of the equipment needed for the forming of the material is reduced by pressing the tees after heating. The tees are suitable for the materials of low carbon steel, alloy steel and stainless steel, especially for the tees with large diameter and thick pipe wall, which are usually formed by this process. Departmental specifications of stainless steel reducers can also be produced by the use of sheet metal stamping forming process. Drawing the use of the shape of the stamping die refers to the stainless steel reducers internal surface design, using the stamping die will be blanked steel sheet stamping and drawing forming.
