High pressure pipe fitting reducer, also known as large and small head, is a type of chemical pipe fittings used for connecting different pipelines. Due to the varying sizes of reducing pipes, there are certain differences in their forming methods. Currently, they can be divided into single pressing forming or multiple pressing forming. So how is the high-pressure pipe fitting reducer made
Although reducers are divided into one-time or multiple compression forming, sometimes expansion and contraction methods are combined according to the needs of material and product forming. Then, based on different materials and diameter variations, determine whether to use cold pressing or hot pressing. In general, cold pressing should be used as much as possible, but for situations where multiple diameter changes cause severe work hardening, wall thickness deviation, or alloy steel materials, hot pressing is more suitable for the production of high-pressure reducing pipes.
High pressure pipe fitting reducer can also be formed by stamping. Stamping is generally only suitable for some special specifications of high-pressure pipe fitting reducer. The shape of the stamping die used can refer to the design of the inner surface dimensions of the high-pressure pipe fitting reducer, and the steel plate after cutting can be stamped and stretched into shape using the stamping die.
