Why Tungum?

Tungum has been in use offshore since 1978 and industry awareness of its superiority for use in marine environments is increasingly evident as more and more operators question the use of stainless steel from both safety and economic viewpoints.

Offshore Usage

In salt-laden marine atmospheres, ‘316’ stainless steel is highly susceptible to crevice corrosion and chloride pitting. After just a few years of salt spray exposure, it may still look bright from a distance, but closer inspection, especially under clamps, reveals the signs of imminent failure.

Tungum alloy tubing, C69100, possesses a natural protection mechanism whereby, on exposure to salt spray, a very thin oxide coating is generated over the exposed surface.
Over time, the tube surface will become discoloured. It may even have a verdigris (green), coating, but under the oxide layer the tube material remains in perfect condition.

Superior Corrosion Protection

BP has approved Tungum tubing for “non process” applications (GP36-15-1). Tungum has passed extensive testing and is segment defined for mitigating and preventing external corrosion on topside small bore tubing.

Long Life Offshore

The long life of Tungum alloy compared to stainless steel gives significant down time savings –  a massive 4 – 6 times the life!

Easy to Work With

Tungum is relatively easy to bend which means fast installation times and reduced costs – typically 1/3 of the installation time of stainless steel.

Industry Compatible

Fits with all industry standard tube fittings.

Benefits for Diving Systems

Builders of diving equipment have found that the ductility and ease of installation of Tungum Tubing offers significant labour cost saving, when compared to stainless steel (as much as 40%.) A large saturation dive system may consist of three chambers, a hyperbaric lifeboat, a diving bell and its handling gear plus control cabin. Such an outfit can consume in excess of 5 km of tubing for the oxygen, mixed gas, air hydraulic and divers water heating system lines.
