    Industry-leading equipment

    Promet AS was among the first in Europe to introduce the use of 5-axis Multi Tasking Machines with revolutionary technology

    We are committed to retaining our position as a leading machining company.
    Our skilled team keeps training up-to-date, and we regularly renew our systems and equipment to ensure our customers benefit from leading technologies

    Our machines can produce parts with a diameter from 1 mm up to 610 mm, and with a length up to 3000 mm. We typically produce in small series, from 1 to 10 pieces but do also serial production

      Working with all materials

      We can manufacture products and parts in all commercial materials and have particular experience of sophisticated and difficult alloys. We have vast experience with materials such as titanium, super duplex and Inconel 718, customised for high-end subsea customers who require materials destined for applications in extreme environments

        Testing to assure quality

        We operate strict quality control procedures, and all our products undergo control according to our Quality Manual before delivery. The materials, processes and products are quality assured according to NS-EN ISO 9001:2000. A close collaboration with partners allows us to perform pressure testing and assembling on-site

          We like a challenge

          We like to look upon ourselves as problem-solvers, constantly experimenting with new materials and focusing on making the seemingly impossible possible. Our operators are regarded as perfectionists with a constant attention to detail, and our products are known for their excellent metal finish

          Promet are specialists in producing high pressure fittings in Inconel, Titanium and Duplex materials. We have a large range of fitting available to order with dedicated part numbers.

          Promet uses EdgeCam software, which when combined with our skilled personel provides accurate machining of complex parts in all materials.
