Bellows Flange

Bellows part: Bellows is an important part of bellows flanges, which has the ability of axial expansion and radial displacement, and can adapt to the thermal expansion and contraction of piping system.
Flange: The flange is the connecting part of the bellows flange, which usually has standardized connection size and shape. It is used to connect the bellows with other pipes or equipments and ensure the reliability and sealing of the connection.
Fastening devices: Bellows flanges usually use bolts, nuts and other fastening devices to connect the bellows to the flange. These fastening devices need to withstand a certain amount of tension and pressure to ensure the firmness of the connection.

1.Material: The material selection of bellows flange should be considered according to the working pressure, medium temperature, medium nature and other factors. Commonly used materials include stainless steel, carbon steel, alloy steel and so on. For high temperature, high pressure or corrosive media, temperature-resistant and corrosion-resistant materials should be selected.
2. Selection: When selecting a bellows flange, the following points should be considered:
Working pressure: Ensure that the high pressure capacity of the flange meets the high pressure operation requirements.
Medium temperature: Select the appropriate material and sealing type according to the medium temperature.
Medium: Consider the corrosiveness and toxicity of the medium and select the appropriate material and sealing gasket.
Connection type: Select the correct connection type according to actual needs, such as bolt connection, welding connection, etc.

1. Installation: Before installing the flange, confirm that the flange, bellows, fasteners and other components are not damaged.
Place the bottom on the flange and secure it with bolts and nuts. When tightening, ensure that the bolts are properly pre-tightened to avoid poor sealing or flange damage due to over-tightening or over-loosening.
After installation, a leak test should be performed to ensure that there is no leakage in the flange connection.

Regularly check the bellows flange connection to ensure that the bolts are not loose or falling off.
If leakage is found at the flange connection, the sealing gasket should be replaced or the bolts should be tightened in time.
For bellows flanges that are subject to high temperature, high pressure or corrosive media for a long time, they should be inspected and maintained regularly to ensure their safe and reliable operation.
