Types of Flanges in Piping Systems

Piping systems play a crucial role in various industries, such as petrochemical, oil and gas, and water treatment. To ensure that these piping systems function safely and effectively, it is important to use the right types of flanges. Arcellor Controls is a leading manufacturer, supplier, and exporter of flanges, offering a wide range of flange types and sizes to meet the needs of various industries and applications. We are committed to providing high-quality flanges that are manufactured to industry standards and codes, ensuring reliable and efficient performance.

Here are some of the most commonly used types of flanges in piping systems:

• Slip-On Flanges

Slip-On flanges are one of the most economical and simplest types of flanges. They are named as such because the pipe is slipped into the flange and then fillet-welded to secure the connection. They are available in a variety of materials, including carbon steel, stainless steel, and high-yield steel, and are commonly used in low-pressure piping systems.

• Weld Neck Flanges

Weld Neck flanges are one of the most commonly used flanges and are characterized by a neck that protrudes from the flange, which is then welded to the pipe. This type of flange provides a strong and reliable connection and is commonly used in high-pressure and high-temperature piping systems.

• Socket Weld Flanges

Socket Weld flanges are similar to Slip-On flanges in that the pipe is inserted into the flange, but in this case, a fillet weld is used to secure the connection. They are commonly used in small-diameter piping systems and are available in a variety of materials, including carbon steel, stainless steel, and high-yield steel.

• Threaded Flanges

Threaded flanges are used in low-pressure piping systems and are designed to be threaded onto the end of the pipe. They are commonly used in applications where the flange needs to be removed frequently, such as in maintenance or repair work. They are available in a variety of materials, including carbon steel, stainless steel, and high-yield steel.

• Blind Flanges

Blind flanges are used to cover and block off the end of a pipe. They are commonly used in applications where the pipe needs to be sealed off temporarily, such as in maintenance or repair work. They are available in a variety of materials, including carbon steel, stainless steel, and high-yield steel.
