How Carbon Steel Flanges Are Manufactured

Carbon steel flanges are essential components in piping systems across many industries.

Step 1: Raw Material Inspection

Qualified steel billets or plates are selected according to ASTM standards.

Step 2: Cutting

Raw materials are cut into suitable sizes.

Step 3: Heating and Forging

The steel is heated and forged into the required shape.

Step 4: Heat Treatment

Normalizing or other heat treatments improve mechanical properties.

Step 5: Machining

CNC machines process dimensions, facing surfaces, and bolt holes.

Step 6: Inspection

Dimensions, material properties, and appearance are carefully checked.

Step 7: Marking and Packing

Products are marked and prepared for shipment.

As a China flange factory, we follow strict quality control procedures to ensure reliable performance for every flange produced.
