Manufacturing Process Of Super Duplex S32750 Flanges
Raw Material
The system controls inspect the raw material quality at the first stage in accordance with the test certificate as well as dimensions and appearance.
Material Cutting
This method of making flanges involves cutting stripes from the center plate and rolling them into a circle.
Forging
Compared to cast flanges, forged flanges typically contain less carbon and are less likely to corrode. Temperature control, weight measurement, and material grade checking are used in forgings.
Heat Treatment
The total forging cooling speed is the slowest throughout this heat treatment procedure; the standardizing and decreasing cooling speeds are faster.
Final Inspection
Measure and check the flange's dimensions and size using this procedure.
