Why you should choose TMC materials for liquid gas applications

30 Mar 2022

Over the last 15 years we noticed several problems with pumping and handling of liquid gasses, LNG and other media used at extreme low temperature with a low viscosity. In most applications the conventional bearing and wear ring materials can not handle these low viscosity and extreme low temperatures.

In these applications the temperature can rise a little and/or the pressure can drop suddenly for short times depending on operation conditions.

With more conventional materials this will cause serious damage to the parts and their MTBR (Mean time between failure) falls down, but many times this is noticed when it is too late. Even little pressure drops in the system are able to cause the bearings to fail, which is why, contrary to liquids, they require lubrication for use with (liquid) gasses.

Our materials are able to handle and survive these critical moments. Tenmax materials always keep their excellent mechanical properties during extreme low temperatures regardless of loading times or media which it comes to contact with.

The TMC materials we recommend for these kind of applications are made for a temperature range from -150C up to 285C. Compared to others they are extreme wear resistant and almost chemical inert while they don't swell in media and don't suffer from aging.

We always advice to use different TMC materials for wear rings and for bearings. Superior materials we recommend for liquid gas applications are TMC 7601, TMC 7601-4, TMC S25 and TMC H60.

Using our TMC materials will give better NPSH and huge savings on energy. But most importantly more reliability and safety!
