ASTM A182 Alloy Steel F22 Weld Neck Flanges are available in different types, including raised face, flat face, and ring-type joint flanges. Raised face flanges are the most commonly used weld neck flange, featuring a small protrusion around the inner bore. This protrusion ensures the gasket sits snugly against the flange surface, providing an effective seal. Flat-face flanges are used in applications where there is no need for a flexible pipe joint. The flange face is flat, and a gasket is typically used to seal the joint. Ring-type joint flanges are commonly used in high-pressure applications. They feature a metal ring in a groove on the flange face, providing a secure seal.

ASTM A182 Alloy Steel F22 Weld Neck Flanges are widely used in various applications that require high strength, corrosion resistance, and durability. They are commonly used in the oil and gas industry, chemical processing, power generation, and offshore construction. These flanges connect pipework systems, valves, and equipment, providing a safe and efficient flow of fluids. They are also used in heat exchangers, boilers, and other applications that require high-temperature resistance.
ASTM A182 Alloy Steel F22 Weld Neck Flanges offer several advantages over other materials. They are highly resistant to corrosion and can withstand high temperatures and pressure. They are also durable, ensuring a long service life, even in harsh and corrosive environments. These flanges feature a precision-machined surface finish, ensuring a tight and secure seal. They are easy to install and require minimal maintenance, making them a cost-effective solution for various industrial applications.
