What are The Types of Pipe Fitting Flanges?

Type of Pipe Fitting Flange

1. Weld neck flanges

To guarantee total tightness, the weld neck flanges—which are welded face-to-face to the pipes—are joined similarly to flat flanges.The kind of connection found is what distinguishes flat flanges from weld neck flanges. Flanges for decoilers. By welding forehead to forehead, they are connected to the pipelines that can be found. In contrast, sealing is supplied in the same manner as flat flanges.

2. Slip-On Flange

These are the flanges where the pipes on the line, which are positioned from both the front and the back, are connected by welding. Bolt holes are used to join decoupled flanges together, and a gasket is positioned between the two flanges to achieve sealing.

3. Socket Weld Flange

These flanges are utilized at the sections where machinery and pipelines are linked. They are considered free flanges because they are movable on the line. To stop the flange from exiting the pipe, the collar is welded to the end of the pipe after the free flanges have been passed on the line. The free flanges don't have any gaskets on them. The surfaces on the collars provide surfaces for sealing and pressing.

4. Threaded flanges
Threaded flanges that are welded to the end of the line are typically employed with threaded flanges, which are mostly utilized in low-pressure lines. These flange types have the same purpose as they are welded to the nipples at the end of the line, possess the same construction as other sections' flat flanges.

5. Blind flanges 

The lines' blind flanges are employed at their termination to guard against the potential for future extensions and continuations of the lines. They are joined to other flanges, just like other flanges, in order to guarantee the line's termination with the aid of a gasket.
