USING SINTEK HTPU PLUS TURNED IN A HYDROGEN ENVIRONMENT

Scenario

The energy crisis has led manufacturers in the energy industry to take increasingly seriously the use of hydrogen as a fuel and as an energy vector. Using it would also be a development in sealing systems present in plants, with seals designed to withstand increasingly high pressure, in certain cases at low temperatures with materials that are compatible with hydrogen and are resistant to wide pressure variations.

Challenge

One of our customers, a leader in the energy industry, asked us to devise a material for developing his hydrogen application that is able to ensure a seal, long-term reliability, resistance to pressure and resistance to low temperatures.

Solution

Inside the ATP test room, using special machines and reconstructing small inner plants have enabled friction forces, wear, durability and also the sealing capacity of different seals made of different materials to be evaluated and analyzed. Studies, analyses and tests have led our technicians to identify SINTEK® HTPU LT PLUS as the most suitable material for the application because of its exceptional resistance properties to low temperatures and the embrittlement temperature around -55°C.

It is this value that enables SINTEK® HTPU LT PLUS to ensure a seal and elastic deformability even at temperatures below -40° C. Its 94 °Sh. A hardness permits higher resistance to high pressure and even repeated high and low pressure cycles and high and low temperature cycles. The experience of ATP in turning has enabled very special sections to be created for seals with high sealing effect in the most extreme operating conditions. The intrinsic qualities of the material make the seals obtained from bars and sleeves extremely reliable and efficient and installation simpler compared with other solutions using plastics.

Testimony

«ATP has been able to provide us with the solution with specific materials with high mechanical resistance, resistance to pressure, to low temperatures and with elastic memory.»
