Types of Flanges
Weld Neck Flange
Weld neck flanges are connected to pipes by welding face to face, ensuring complete tightness similar to flat flanges. The primary difference between weld neck flanges and flat flanges lies in their connection type. Decoiler flanges, which are also welded forehead to forehead to pipes, provide sealing in the same manner as flat flanges.
Slip-On Flange
A slip-on flange is a type of pipe flange that slips over the end of a pipe and is then welded in place on both the inside and outside. This design makes it easy to install and cost-effective, commonly used in low-pressure applications. Slip-on flanges are ideal for systems requiring frequent disassembly and are widely used in various industries for their simplicity and reliability.
Socket Weld Flange
These flanges are used in the parts where pipelines are connected to machines. Because they can move on the line, they qualify as free flanges. After the free flanges are passed on the line, the collar is welded to the end of the pipe to prevent the flange from coming out of the pipe. There are no gaskets on the free flanges. Seal pressing surfaces are provided thanks to the surfaces located on the collars.
Threaded Flange
Threaded flanges, which are mainly used in lines where the pressure is low, are usually used together with nipples that are welded to the end of the line. These types of flanges, which are used by being welded to the nipples at the end of the line, have the same structure as flat flanges in other parts.
Blind Flange
The blind flanges used in the termination of the lines are used against the possibility that the lines will be extended and continued later. Like other flanges, they are connected to other flanges with the help of a gasket to ensure the termination of the line.
Lap Joint Flange
A Stub End Flange, more commonly known as a Lap Joint Flange, is used in conjunction with Stub Ends. The Stub End adapter slides through the flange and is welded to the pipe. Similar to the Slip On Flange, the Lap Joint Flange features a flat face and a machined radius at the bore, allowing it to rotate freely around the Stub End for easy alignment with the mating flange.
