General

Industrial flanges come in a variety of sizes to accommodate different applications. The size of a flange is typically given in terms of the Nominal Pipe Size (NPS), which can range from 1/2 inch to 24 inches according to ANSI (American National Standards Institute) standards. There are also larger sizes available, up to 48 inches or even more, depending on the specific requirements.

Flanges also have different classes that indicate their pressure capacity. These classes include 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, and 2500 LBS. The class, along with the flange size, determines the dimensions such as bolt circle diameter, bolt hole size, thickness, and overall diameter.

It’s important to note that the actual dimensions can vary based on the flange type and standard followed, which could be ANSI, ASME (American Society of Mechanical Engineers), DIN (Deutsches Institut für Normung – German standard), among others. Therefore, it’s crucial to refer to the specific standard or consult with a flange manufacturer or supplier for the precise dimensions.

Flanges are a crucial component in many industries due to their role in connecting pipes, pumps, and valves to create a smooth and efficient piping system. Here are some of the key industries that use flanges:

Petrochemical Industry: Flanges are widely used in this industry for constructing intricate pipe networks for the transportation and processing of petrochemicals.
Oil and Gas Industry: They play a critical role in oil and gas production, helping connect pipes and equipment in drilling sites, refineries, and transportation facilities.
Construction Industry: Flanges are used in the construction of buildings and infrastructure, particularly in plumbing systems, HVAC installations, and fire protection systems.
Power Generation: In power plants, including nuclear, coal-fired, and hydroelectric facilities, flanges are used to connect pipes and equipment in the complex systems used to generate electricity.
Water Treatment: Flanges are used in water treatment facilities for the assembly of pipe systems that carry water and wastewater.
Shipbuilding Industry: They are used in the construction of ships, particularly in the assembly of piping systems for fuel, water, and waste.
Food and Beverage Industry: In this industry, sanitary flanges are used in piping systems to ensure cleanliness and prevent contamination.
Pharmaceutical Industry: Similar to the food and beverage industry, sanitary flanges are also used in the pharmaceutical industry to maintain sterile environments.

It’s important to note that the type and specifications of flanges used can vary greatly depending on the specific needs and standards of each industry.
