OPENSUPPLY, Your supplier of Flanges

Having the right quality flanges is essential to a reliable process. OpenSupply has a wide range of suppliers and flanges. To supply you with the best market standard of every type of flange.

OpenSupply supplies the following Flanges:

1) Welding neck flange
The welding neck flange is equipped with a slanting collar with which the flange can be welded to a duct or appendage.

2) Slip-on flange
Unlike the welding neck flange, the slip on flange is not equipped with a collar. Instead, it is welded straight onto the duct or appendage.

3) Connecting flange
Connecting flanges are used to (temporarily) close off ducts by applying the flange between two duct parts.

4) Spectacle flange
Spectacle flanges are used in combination with a connecting flange to (temporarily) close off ducts by applying the connecting flange between two duct parts.

5) Blank flange
Blank flanges are used to (temporarily) close off (or blank) ducts, for instance in the case of older ducts or to allow for maintenance work.

6) Threaded flange
A wire flange is, in essence, similar to other flanges. However, the thread flange is provided with screw thread for specific applications.

7) Lap joint flange
Spectacle flanges are used in combination with a connecting flange to (temporarily) close off ducts by applying the connecting flange between two duct parts.

We are also happy to provide various solutions in the area of gaskets, vitrified tile connecting systems, tubes, fittings, welding components and (automated) valves.
