]]> On October 7, we received an inquiry from an old customer in Vietnam for flanges, forged pipe fittings, and some customized elbows. The product in this inquiry is basically the same as the previous order，and the customer is very satisfied with the previous batch of goods.

After reviewing our quotation, the customer discussed the details of the order with us, including packaging, transportation, delivery time and other issues. Finally, we received the customer’s order. This is our second cooperation with the client.

Below is purchase order list

Carbon Steel Forged Flanges

Forged flanges are flanges manufactured by forging technology, which have excellent mechanical properties and reliability. The forging process makes the internal structure of the material more compact, eliminates defects such as pores and inclusions, thereby improving the strength, toughness and corrosion resistance of the flange. Forged flanges are widely used in high pressure, high temperature and corrosive environments such as petroleum, chemical, electric power, shipbuilding and nuclear industries.

Manufacturing Process of Forged Pipe Fittings and Forged Flanges

The manufacturing process of forged pipe fittings and forged flanges mainly includes:

1. Raw material preparation: Select suitable metal materials, such as carbon steel, alloy steel, stainless steel, etc.

2. Cutting: Cut the raw materials into suitable lengths according to the product size.

3. Heating: Heat the raw materials to a suitable temperature for forging.

4. Forging: Forge the heated raw materials into the required shape by free forging or die forging.

5. Cooling: Cool the forgings to room temperature.

6. Heat treatment: Heat the forgings as needed to improve their mechanical properties.

7. Machining: Machining the forgings to achieve the required size and accuracy.

8. Inspection: Inspect the forgings to ensure that their quality meets the requirements.
