Efficient manufacturing

Many of the materials we work with are expensive and complicated to process. Products are therefore designed in a way that minimizes material consumption. The manufacturing process is highly efficient, keeping costs down for our customers. Our manufacturing unit produces pressure vessels in titanium, aluminum, acid-resistant steel, carbon steel, hastelloy, SMO254, duplex and super duplex and masters the pressure vessel standards:

We specialize in titanium welding.

We know how to design, form and weld customized products that have high strength and resistance requirements and at the same time have a low weight.

Titanium welding! Most of the time we work with homogeneous material, which is often both the best and most economically advantageous. Sometimes, however, other solutions are required, such as explosive bonding or loose lining, where a vessel is lined with a thin sheet of titanium. Titanium is difficult to weld and requires special skills and protected environments as the material changes if it comes into contact with oxygen during welding.

We weld according to standard EN ISO 3834-2 and all Örnalp Unozon welders are licensed to ensure a high and consistent quality of work.
