Chemical processing – Oil & Gas

The industry-required temperatures, loads and chemicals call for materials that can handle the extreme elements. Our USA supplier Quadrant continues to provide the widest product portfolio of Advanced Engineered Materials and General Engineered Materials for the market, with advantages such as:

  • Improved product efficiency with tighter tolerances and lower wear materials
  • Reduced weight and power requirements by switching metal components to plastic
  • Resolved heavy corrosion problems in harsh environments
  • Reduced VOC Emissions – superior materials for seal elements help reduce leaks impacting the environment
  • Reduced friction and superior co-efficient of linear thermal expansion (CLTE) improve performance and design of components
  • Increased equipment lifetime
  • Reduced maintenance cost with easy to clean non-stick materials
  • Quadrant materials comply with many common industry specifications, such as ISO, ASME, Norsok, API and NACE

Alternative Energy

LEP, supported by Quadrant Plastics, has been a solution provider for the energy generation industry for many years.

Our expertise is built on application successes in traditional energy sectors like oil & gas, but more and more in emerging alternative energy fields such as wind and solar.

Our materials are extensively tested and able to operate under harsh chemical and even extreme thermal conditions.

Our high performance materials offer the advantages of all plastics, helping to reduce weight and allow for the substitution of other materials like steel, aluminium or ceramics, due to their high specific strength.

Solar: Our materials have been tested and certified for applications in vacuum chambers offering very low out gassing. We also offer materials for wet process environments presenting low out leach values.

Custom Solutions for the Industry

Crown Seals for Hydro Power Station

Crown Seals

The objective for the Hydro Power Station was to replace a metal crown seal with an abrasive resistant plastic seal for increased wear in a high pressure environment, as well as reduced downtime through less-frequent replacement. The plastics seals are also lighter and easier to install.

Swing Ring Bearing for Hydro Power Station

Swing Ring Bearings

Produced for Hydro Power Station, these bearings are used on the periphery of the swing ring which actuates wicket gates, controlling water flow into turbines in hydro power station. While turbine speed is constant, for more power the induced current is increased resulting in greater torque on the bearing. These are low/slow speed bearings chosen for zero stick slip.

Polyurethane Pump Parts

Polyurethane Pump Parts

Large (300mm) end plates for pumps to handle dirty water conditions. Polyurethane has been used for it’s wear resistance capabilities with aggressive materials.
