We are 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.

PROCESSING

  • tapering wallthickness from (S) – from ½“ to 24“
  • larger dimensions of up to 16“ can be ground
  • turn out inner diameter – from ½“ to 24“
  • processing of welding bevels in compliance with DIN 2559 / EN ISO 9692-2 / ASME B16.25
  • sawing elbows at any angle – from ½“ to 24“
  • surface machining on flanges – Rz, Rth 0.5 – 160
  • axial grooving – e.g. spring/groove
  • internal grooving

PRODUCTION

  • concentric and eccentric reducers from ½” to 12“
  • tees from ½” to 6“
  • threaded fittings (nipples, couplings, caps) – from ½” to 4“ – R, Rp, G, NPT
  • hexagonal parts (e.g. hexagonal plugs, hexagonal nipples) – from ½” to 4“

We produce single parts and small series with a dimensional accuracy of 0.1 mm
Other parts according to drawings
