Push-In Flange Protectors

Pipe flange refers to the flange used for piping in the pipeline installation and refers to the inlet and outlet flange of the equipment used in the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets.

The flange is divided into threaded connection (thread connection) flange, welding flange, and clip flange. Flanges are used in pairs, low-pressure pipes can use wire flanges, welding flanges for pressures above 4 kg. Add a gasket between the two flanges, and then tighten with bolts. Flanges of different pressures have different thicknesses, and they use different bolts.

To extend the service life of the flange, the daily maintenance of the flange is very important.

The Push-In Flange Protectors can protect the outside of the flange and play a role in preventing oxidation and corrosion.

In addition, the Push-In Flange Protectors have a strong dustproof effect, which not only extends the service life of the flange but also keeps the flange surface shiny.
