Abstract
A method of testing a shape-memory alloy (SMA) coupler for use within an oil and gas environment at an operating pressure includes testing a first specimen of an SMA coupler design for the operating pressure according to a first test sequence comprising a first plurality of tests and testing a second specimen of the SMA coupler design for the operating pressure according to a second test sequence comprising a second plurality of tests. The method further includes approving the SMA coupler design for use within an oil and gas application at the operating pressure if the first specimen passes each of the first plurality of tests of the first test sequence and the second specimen passes each of the second plurality of tests of the second test sequence.
