What should pay attention to when making stainless steel reducer

Forming hole diameter is less than stainless steel reducer big end diameter of the tube billet, used in die forming along the tube billet diameter hole enlargement. Hole enlargement technology mainly to solve the stainless steel reducer in the variable diameter is larger not easily by reducing forming, sometimes according to the requirements of the materials and products forming, expanding and reducing method of combination.
In the process of reducing or expanding deformation, according to different materials and variable diameter, determination by cold pressing and hot pressing. Under normal circumstances, as far as possible by cold pressing, but the multiple variable diameter and cause serious work hardening of the thick or alloy steel, wall thickness of materials appropriate USES hot pressing.
In addition to the use of stainless steel pipe as raw material to produce stainless steel reducer, the part of the specifications of the stainless steel reducer can also be used steel plate stamping forming technology is adopted to improve the production. Drawing die shapes used by reference to reducing tube surface size design, use after blanking punching die, stamping steel stretch forming.
stainless steel reducer used in what place?
1, when the fluid flow in stainless steel pipe have change, such as increasing or decreasing, velocity requirements haven’t changed much, all needs to use stainless steel reducer.
2, the inlet of pump, in order to prevent cavitation, requires a stainless steel reducer.
3, and instrumentation, such as flow meter, the regulator shall, in order to cooperate with the joint of the instrument, also need to use stainless steel reducer.
