CONCLUSION

New testing high pressure facilities available at CTE since end 2006

At different temperature range for cylinders With hydrogen, at various temperature on components

First learning on high pressure components and cylinders

These equipments enable us to develop any specific test, with respect to standards or to any customer specification on high pressure cylinders or components
