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.
Tungum Tubing is widely used in the oil and gas market for high quality, safety critical applications.
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.
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.

For many years, Tungum UNS C69100 tubing has been considered a superior material for installations in the harsh environments experienced by the oil and gas, dive, transport and marine industries. There was a need to re-assess and bring up-to-date the […]Read more on this story
To help better understand Tungum and where it can be used we offer Tungum T-Talk sessions. These can be done at anytime of day including lunch times and typically last approx. 1 hour.
