Lean Duplex 2101 Flanges

Manufacturing Process Of Lean Duplex 2101 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.
