Reducer, also known as a reducing elbow, unequal tee, or reducer, is a type of chemical pipeline fitting used for connecting pipes of different diameters. It comes in two shapes: concentric reducer and eccentric reducer. Materials for reducers include stainless steel (304, 304L, 316, 316L), alloy steel, carbon steel reducers, with options such as 20# steel, Q235, Q345, 16Mn, etc.
Standard size reducers in Chinese, American, and British standards, as well as various non-standard products.
Elbows (Reduced Bends) are pipe fittings used for varying pipe diameters. The commonly used forming processes include reduced diameter pressing, expanded diameter pressing, or a combination of both. For certain sizes of reduced bends, stamping forming can also be employed. The reduced diameter/expanded diameter forming process involves placing a tube blank with a diameter equal to the larger end of the elbow into a forming die, then pressing along the tube blank's axial direction to cause the metal to move within the die cavity and shrink into shape. Depending on the size of the diameter change in the elbow, it can be formed in one press or multiple presses. Stamping forming In addition to using steel pipes as raw materials for producing elbows, stamping forming processes can be used to manufacture some sizes of elbows with steel plates. The shape of the stamping die used for stretching is designed based on the internal surface dimensions of the elbow, and the steel plate after blanking is stretched into shape using the die.
