DHSV Testing

Our Down Hole Safety Valve test stand is capable of testing DHSVs at pressures of up to 20,000psi (1,379bar) and temperatures of up to 250ºC.

The test rig was specifically designed and built to operate to any industry standard or test method and can be adjusted to conduct modified testing protocols as required. This capability combined with our material compatibility test facilities allows a full qualification of DHSV’s to be conducted under one roof.

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.
