A flange is a collar, solid disk, or ring that attaches different piping equipment. These flanges play a pivotal role in allowing or restricting the flow of fluids and gases in the system. A flange is installed in the system by welding it directly to the module; however, they can be also threaded or lap-jointed for specific applications.
A flange connection is materialized by drilling equally spaced bolt holes that align it to the subsequent machining flange. Both these components are fastened, making use of bolts. The bolt patterns can be determined by industry specifications or customer requirements. Standard flanges are manufactured following industrial specifications set by the ASME B16.47, ANSI B16.5, API, MS-SP44, and AWWA-C207. These versatile modules are designed with pressure ratings from 75# up to 2500#.

Flanges are designed in different sizes to meet different requirements. The key sizes of flanges are:
Forged flange- Forging of steel is a process that makes use of mechanical and thermal energy for producing steel billets and ingots, allowing the items to be shaped precisely. The high-strength flanges are utilized in high-pressure and temperature systems and have a consistent composition and grain structure. The costs of these flanges are higher due to the complex processing costs.
Plat flange- These flanges can be manufactured either by casting or forging the steel grade. The flat circular flanges are not preferred in high-pressure and temperature systems. These flanges possess a superior grain structure over standard forged or cast flanges. The cost of the flange depends on the processing type.
Cast flange- Casting is a process wherein metal is heated until it is molted and then poured into molds to get desired shapes. They don’t possess a uniform grain structure and may have defects in their formation. The flanges in this range are susceptible to high temperatures. They are, however, cheap to manufacture and process.

Standard flanges are designed with a raised and flat face. Both these face types can be differentiated based on different characteristics.
Korean flange is a standard of steel that is manufactured by following the KS D Korean standard. The standard of these flanges is slightly similar to the Japanese JIS standard. The flanges in this standard are SORF, WNFR, BLFF, BLRF, and SOFF. The flanges in this grade possess a pressure rating of 5k, 10k, 16k, 20k, 30k, 43k, and 63k. These flanges are a feature in nuclear power plants, petrochemicals industries, acid production systems, and oil refineries.

ANSI and ASME flanges belong to important organizations of the metal industry. Understanding the difference between both these standards will help in selecting the correct equipment that adheres to specific standards
Flanges are common equipment in connecting different piping equipment. Most often, they’re exposed to corrosive media and may degrade over time. To ensure the best products are supplied the purchaser can run inspections before finalizing the purchase.
Below are important inspection and test codes.
The inspection and test plan can also be changed based on the purchase order or classes listed below.
