Class 150 Hot Dipped Galvanized Forged Carbon Steel Threaded, Raised-Face Flange
Class 150 Hot-Dipped Galvanized A105/SA-105 Threaded Raised-Face Flange
The Class 150 ASTM A105 / ASME SA-105 Hot-Dipped Galvanized Forged Carbon Steel Threaded Raised-Face Flange provides a strong, corrosion-resistant connection for industrial piping systems where a threaded installation is preferred. Combining forged carbon steel strength, internal pipe threads, a protective galvanized finish, and raised-face construction, this flange provides dependable performance without requiring a pipe-to-flange weld.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, this Class 150 threaded flange provides excellent mechanical strength, toughness, and durability. A105/SA-105 forged carbon steel is widely used for pressure-containing components in industrial processing, manufacturing, utilities, water systems, mechanical piping, and general-purpose industrial piping applications.
The Class 150 designation represents a pressure class rather than a maximum working pressure of 150 PSI. Actual allowable pressure depends on flange material, size, operating temperature, and applicable pressure-temperature ratings.
Threaded Flange for Convenient Installation
A threaded flange incorporates internal pipe threads that connect directly to compatible externally threaded pipe. This design eliminates the need to weld the pipe directly to the flange, making threaded flanges useful for installations where welding is undesirable, impractical, or restricted.
Thread type, pipe size, pressure rating, and service compatibility should always be confirmed before installation.
Hot-Dipped Galvanized Corrosion Protection
The hot-dipped galvanized finish provides a protective zinc coating over the forged carbon steel. This coating helps resist atmospheric corrosion caused by moisture, humidity, weather exposure, and many outdoor environments.
Raised-Face Flange Construction
The raised-face (RF) design features an elevated gasket seating area that concentrates bolting force over the gasket to help create a dependable seal with a compatible mating flange.
When ordering a Class 150 galvanized A105/SA-105 threaded raised-face flange, verify nominal pipe size, thread requirements, Class 150 rating, raised-face configuration, galvanized finish, gasket selection, dimensional standard, and service conditions for proper piping system compatibility.
