Threaded Flange

Threaded flange

The threaded flanges are characteristic for not using welding for their installation, which allows an easy and fast assembly. It is not advisable to use threaded flanges in conduits where there are considerable temperature variations, since due to the expansion of the pipe, losses can be created through the threading after a period of work.
