ASTM A182 F11 alloy steel tongue and groove (T&G) flanges are precision-engineered components used to join two sections of pipe with a secure and robust connection. These flanges are made from Grade F11 alloy steel, which provides excellent strength and durability under high-pressure and high-temperature conditions. The tongue and groove design features a projecting tongue on one flange and a matching groove on the other, which helps to align and seal the connection effectively. This type of flange is often used in applications where a tight, leak-proof seal is critical, such as in the oil and gas, petrochemical, and power generation industries. The flanges are designed to meet strict ASTM standards and offer reliability and performance in demanding environments.
