Werner Kemminer GmbH
Special plant for flanges and circlips

Since its foundation in 1962, our company has specialised in the production of flange rings and later, as of 1997, also in the production of circlips.

During subsequent years, this specialisation lead to an enormous expert potential in the flange but also in circlip production, which we convey to our customers in the form of consulting and support. Together with our customers, we have been able to develop and realise numerous individual problem solutions.

Due to our specially developed cold-bending procedure we are able to produce flat, square or round profiled flange rings at nominal widths 63 to 2000 as particularly cost-efficient and with a high degree of dimensional accuracy. We also produce flange rings, ring segments, segment arches etc on table track bending machines consisting of the most varied steel profiles and steel types.

Our standard delivery program is completed by the two-part circlip with "knee joint", developed by ourselves. This enables the rapid and cost-efficient assembly on winding slip joint tubing and other thin-walled piping with wall thicknesses of 1 mm and 2-3 mm.

Our entire delivery program is even more versatile and entails the following:
