Flanges are essential components used in piping systems to connect pipes, valves, pumps, and other equipment. They provide a secure and leak-proof connection, ensuring the safe flow of fluids and gases. Flanges are typically made from materials like carbon steel, stainless steel, or alloy steel and come in various types, such as weld neck, slip-on, blind, and socket weld, each designed for specific applications. Widely used in industries such as oil and gas, petrochemical, power generation, and construction, flanges ensure easy assembly, disassembly, and maintenance of piping systems.

Flange Types We Specialize In

Weld Neck Flange

Weld Neck Flange

A Weld Neck Flange is a type of flange with a long neck that is welded to the pipe, providing a strong and reliable connection for high-pressure applications.

Slip On Flange

Slip On Flange

A Slip-On Flange is a type of flange that easily slides over the pipe and is then welded in place, making it a cost-effective option for low-pressure applications.

Blind Flange

Blind Flange

A Blind Flange is a solid flange used to close the end of a piping system, effectively blocking the flow of fluids and providing a secure seal for maintenance.

Socket Weld Flange

A Socket Weld Flange is designed to connect pipes by inserting the pipe into a recessed area of the flange and then welding around the outside for a strong, leak-proof connection.

Orifice Flange

An Orifice Flange is used in conjunction with orifice plates to measure the flow rate of liquids and gases in a piping system, with pressure taps for accurate measurement.

RTJ Flange

An RTJ Flange (Ring Type Joint Flange) is a high-pressure flange with a metal ring gasket that fits into a machined groove, ensuring a leak-proof seal in critical applications.

Demo Image

Threaded Flange

A Threaded Flange is a type of flange that has internal threads, allowing it to be screwed onto a pipe without welding, typically used in low-pressure and non-critical applications.

Demo Image

Lap Joint-Flange

A Lap Joint Flange is used with a stub end fitting, allowing the flange to rotate freely around the pipe, providing easy alignment and installation, typically in systems requiring frequent disassembly.

Demo Image

Spectacle Blind Flange

A Spectacle Blind Flange is a safety device in piping that features a flat disc and a curved section, allowing operators to easily switch between blocking and allowing flow.

Demo Image

Nipoflange

A Nipoflange is a type of flange that incorporates a short stub of pipe, allowing for easy connection to other pipes or equipment while providing a strong, leak-proof joint.

Demo Image

Weldoflange

A Weldoflange is a flange designed for welding directly to a pipe, providing a robust and permanent connection suitable for high-pressure applications.

Demo Image

Forged Flange

A Forged Flange is a flange made from forged steel, providing superior strength and durability, typically used in high-pressure and high-temperature applications for reliable connections in piping systems.
