Tungum Tubing

designed to perform in safety critical applications

Great Product and Real Added Value


Using stainless steel you can expect 5-10 refits over the life of a rig, plus the costs involved in rig shut down and ‘old’ tube disposal. To benefit from reduced operating costs of Tungum Tubing there will be an initial higher outlay, which will be recovered several times over during the typical lifetime of a facility. For example, the price of instrumentation tubing for a standard oil rig using stainless steel compared with using Tungum Tubing is approximately half.

What is Tungum?

Tungum Alloy (Aluminium-Nickel-Silicon-brass) combines:

  • an unusually high strength to weight ratio
  • good ductility
  • excellent corrosion resistance
  • first class fatigue properties


Tungum’s high proof to ultimate stress ratio enables system proof tests to be conducted well above working pressure, without risk of permanent set taking place.

When used in high pressure hydraulic or pneumatic circuits, these features together with inherent “clean bore” characteristics combine in affording an easily constructed, high integrity system. This requires a minimum of purging and no external protective treatment.

Benefits

  • Highly resistant to sea water and its atmosphere, Tungum resists both stress and crevice corrosion to offer outstanding serviceability, even at intermittent duty in the highly corrosive ‘splash’ zone.
  • Non-magnetic and non-sparking properties make Tungum invaluable in piping high pressure gases, particularly oxygen where its thermal conductivity/ defusivity characteristics virtually eliminate the potential dangers present when lesser materials are employed.
  • Tungum Alloy is a cryogenic material, suitable for chemical engineering and low temperature processes. Its corrosion resistance often enables its use in conveying fluids and gases containing corrosive elements.

Tungum alloy possesses a natural protection mechanism whereby, on exposure to salt spray, a very thin oxide coating is generated over the exposed surface, no more than two thousandths of an inch thick, when complete. The tube becomes discoloured, it may even have a verdigris coating, but under the oxide layer the tube material is perfect and will remain so for a very long time. Tungum has been in use offshore since 1978 and industry awareness of its superiority for use in marine environments is increasingly evident.
