Fatigue Testing

BHR Group has two test rigs dedicated to fatigue work. Both the rigs are controlled by a microprocessor-based system which affords complete closed loop control of impulse pressure and vibration waveforms. Parameters such as pressure rise time, impulse test pressure, and rate of decay, can be specified and then maintained accurately throughout the duration of the test.
As well as carrying out fatigue investigations to a client's specific requirements, the following test procedures are among those which can be accommodated:

• BS 4368-Part 4 - compression couplings
• CEGB Standard 236601 - compression couplings
• Lloyd's Register of Shipping requirements for compression couplings used on offshore and marine installations (BHR Group is a Lloyd's approved test house)
• Pressure impulse testing of hydraulic hoses to SAE and BS specifications.
• AHEM/R.M.P 3/82 - Test method for the determination of fatigue pressure rating for metal pressure containing envelopes in hydraulic fluid power systems.
