WITTE. The Flange People

Fast and customised.

Even for parts that are not in the warehouse, we find a solution. In our machining center we rework flanges, fittings and bends – according to your wishes and specifications. In order to meet the ever-increasing demands of the market, we are constantly expanding the machine park, promoting our employees, and needless to say, we are PED and AD-2000 WO certified.

In addition to machining, welding, fittings and flanges, we can also produce parts from solid material.


  • tapering wallthickness from (S) – from ½“ to 24“
