Reducing forming technology of high pressure reducer

The tube is placed in the forming die with the same diameter as the large diameter of the high pressure reducer, and the metal is moved and contracted along the mold cavity by pressing in the axial direction of the tube. Press forming or multiple press forming.

High pressure reducer is characterized by significantly higher strength than the same carbon carbon steel, with good toughness and plasticity and good weldability and corrosion resistance.

High pressure reducer as a side is flat, conducive to the exhaust or drainage, easy to drive and maintenance, so the level of the installation of liquid pipes generally use high pressure reducer. The diameter of the reducer should not be greater than 1% of the corresponding diameter of the corresponding end, and the allowable deviation of ± 3mm; reducer if the selected diameter specifications and process pipe diameter does not match, should be the corresponding reduction or diameter processing, If the pipe is throttled, consider whether the pressure loss caused by this will affect the process flow. In order to prevent the installation of reducer after the impact of the flow field distribution, resulting in loss of pressure, thereby reducing the measurement accuracy of electromagnetic flowmeter, the required center cone angle α is not greater than 15 °, the smaller the better. There are two kinds of concentric and high pressure, concentric reducer is generally used in the vertical tube; high pressure reducer for the horizontal tube, and should pay attention to marked the top or bottom level.
