Large diameter seals and backup rings

Seal Engineering AS has been in the forefront delivering very large diameter profile seals in polyurethane and rubber to hydropower and wind turbines, test chambers, autoclaves, wellhead equipment - and many more!

So, if you are experiencing problems with:

  • Extrusion
  • Large diameters
  • High pressures
  • Large gaps
  • High temperatures
  • Agressive chemicals

...then do not hesitate to contact us!

Not only do we produce high quality, large diameter seals, but we make sure that they are allowed to work under the best conditions - due to our production capability on large diameter PEEK back-up rings. We have already celebrated production of more than 1000 pcs of seals larger than ø1000 with one or two back-ups, and are rapidly expanding the scopes.

Fast and flexible production

Continuing with our experience and the demand for large diameter seals in thermoplastics we have been able to successfully develop and demonstrate a technique of manufacturing very large diameter backup rings in PEEK for the same seals for use in high pressure and/ or large extrusion gaps.

Low lifetime cost

Manufacturing backup rings > 500 mm in diameter in any material - let alone PEEK, is an expensive proposition. The new technique has helped us to conquer the size, time and cost to deliver large size rings (theoretically, without limitations) quickly. The rings manufactured thus have undergone critical laboratory tests in-house and we found that the strength of the material is consistent throughout the circumference. Customers can now safely order seals and backup rings for quick delivery.

Large diameter rotary swivel seals

In our continuous endure to support the oil and gas industrial segment we have been able to successfully design, develop and deliver polymer sealing solutions for various large diameter rotary swivel stacks, marine industry applications, single and multi-flow CALM Buoys, SALM Buoys, turret mooring buoy swivel systems, fluid transfer couplings, etc., handling various types of chemicals, condensates, fuels, water, emulsions, hydraulic fluids and gases that are commonly used in the oil and gas industry.
