Thermoplastic Umbilical Testing

We have a large number of individual test rigs capable of testing thermoplastic umbilical hoses at a range of temperatures, durations and pressures on both hydraulic fluids and production chemicals.

Our sophisticated software package allows us to run test cycle durations in accordance with ISO 13628-5 and/or to customer specific requirements. With advances in fluid technology and research into new materials, pressure cycling plays an important role in ensuring the fluid/material combination will meet service life demands.

Please refer to the tables below for more information on the test rig capabilities and typical testing we offer and do not hesitate to contact us to discuss your requirements.

’if a fluid touches it, we can test it!’
