Audited Supplier A thread flange is a type of flange that has threads on the inside surface of the flange bore which match the threads of the pipe. This design allows the pipe to be screwed directly into the flange, eliminating the need for welding. Threaded flanges are commonly used in low-pressure or non-critical applications because they can be installed and connected to pipes without welding. They are especially useful in applications where welding is hazardous or not feasible, such as in highly explosive environments where welding could pose a risk of ignition.
Threaded flanges are available in various sizes and materials to match the pipes they will be used with. They are often chosen for small diameter piping systems and are not recommended for use in piping systems where high pressure, high temperatures, or severe mechanical stresses are present. Despite their limitations in high-pressure environments, threaded flanges offer a convenient and cost-effective method for connecting pipes in a wide range of applications.

RAISED FACE: Features a raised area around the bore, common in many high-pressure applications and allows for a variety of gasket types.
RING-TYPE JOINT (RTJ): Features a grooved face that holds a metal ring gasket, used in high-pressure and high-temperature applications.
LAP JOINT: Often used with a matching stub end, this face allows for easy alignment and is used primarily in systems that require frequent maintenance.
TONGUE AND GROOVE: One flange has a raised ring (tongue), and the other has a depressed ring (groove); they fit into each other to form a tight seal.
MALE AND FEMALE: Similar to tongue and groove but more exaggerated; the male flange has an additional lip, and the female flange has a corresponding recess.
