Slip on Flange 6 Inch

Slip-on flanges are usually only used for pipes. To connect slipon flanges, two weldings are usually used, one inside the hole and the other outside it. In these flanges, the central hole is larger than the diameter of the pipe; so that the pipe passes through the middle of this hole and is connected to the flange with a strip weld. The slipon type flanges usually have much lower temperature and pressure tolerance than welded throat flanges. One of the most important reasons is that in this category of flanges, due to the absence of the throat part, the available pressure is It is not divided equally between the pipe and the flange; Therefore, in the long run, they usually show less resistance


Weld Neck Flange 6 Inch

In this particular type of flanges, there is a tube-like part or throat as the body of the flange, the diameter of the end of this neck is the same as the diameter of the pipe. Due to their special shape, welded throat flanges do not physically create a pressure difference at the connection point compared to other points of the tank. On the other hand, usually the diameter of the throat part is designed corresponding to the diameter of the pipe. As a result, they do not disrupt the material flow and do not change the shape of the parts around the connection point.


Ring-Type Joint Flange

Usually, these flanges are used in situations where there is a need for metal sealing. These conditions usually occur when the pressure and temperature are very high (for example, above 600 degrees Celsius). In these flanges, a metal gasket is used, which is placed between the corresponding grooves. As the flange closes and the pressure increases, this metal gasket deforms and creates a strong metal sealing shield. In order for this to happen, the material of the gasket used must be much softer than the material of the flange itself and have high hammerability.


Threaded Flange 6 Inch

The difference between threaded flanges and slipon flanges is in the main opening of the flange itself, which threaded flanges have a thread that can be used to connect the equipment to the tank. In most cases, the threads on the flange match the threads created on the pipe or the existing threads on the equipment. Although these flanges are produced with various pressure standards, they are usually used in cases and conditions where high temperature and pressure are not considered. Also, one of the most important applications of this particular type of flanges is in tanks that contain gases, vapors, and explosive dust.
