Industry Forged Flanges-ASME/ANSI Standard and Non-standard

Forged flange is a plate-type device, usually in circular appearance, which could be attached to the ends of pipes, fittings, valves, or other objects to facilitate assembly and disassembly of the piping system. It offers impressive mechanical performance as a connecting part.

Forged steel flange has higher precision and performance than the cast flange and is widely used in different industries for connecting equipment or pipelines, especially for high temperature and high pressure environments.

Types of Forged Flanges

Industrial welded forged flanges come in many different types. Each species meets its special requirements. For example, long weld neck flanges are attached to the necks of the pipes.
There is also have weld neck flange

• weld neck flange;
• threaded flange;
• slip-on flange;
• lap-joint flange;
• blind flange;
• Plate flange

• MSS-SP44: For steel pipeline flanges
• API 605: For large diameter carbon steel flanges

Production process

Industrial Forged Flanges Key Applications:

1. Oil and Gas Industry:
Forged flanges are essential in oil and gas extraction, transportation, and refining processes. Their ability to withstand high pressure and temperature makes them suitable for pipelines, refineries, and offshore platforms.
2. Petrochemical and Chemical Plants:
These welded forged flanges are used to connect pipes and equipment handling corrosive chemicals in petrochemical and chemical processing plants. Materials like stainless steel and specialized alloys are often employed for their corrosion resistance.
3. Power Generation:
Forged flanges play a vital role in power plants, including nuclear, thermal, and hydroelectric facilities. They connect piping systems transporting steam, water, and other fluids under high pressure and temperature.
4. Water Treatment and Distribution:
They are used in water and wastewater treatment plants to ensure reliable fluid transport in pipelines and systems.
5. Shipbuilding and Marine Applications:
In marine environments, forged flanges provide durable and corrosion-resistant connections in pipelines on ships and submarines.
6. Food and Pharmaceutical Industries:
Where hygiene and corrosion resistance are critical, forged flanges, particularly those made of stainless steel, are used in processing equipment for handling sensitive liquids and gases.
7. HVAC Systems:
Forged flanges are also used in heating, ventilation, and air conditioning (HVAC) systems for reliable connections in piping networks.
8. Structural Applications:
In some cases, forged flanges are used in structural frameworks for added support and stability.

Why Buy Flanges in Bulk from RAYOUNG?

We make thousands of ASME B16.5 flange units every month. When you buy in bulk, we give you better prices.
