Specialised valves for the Petrochemical and Natural Gas industries require extensive performance and qualification testing to meet international standards such as API Specification 6A, Appendix F, PR2 level and ISO10423:2001.
Test procedures define a sequence of valve operations at varying
upstream and downstream pressures, varying valve positions and varying
ambient and valve body temperatures from -40°C to 160°C.
A legacy valve test rig had operated in manual mode only and although
it had previously been upgraded by another company for automatic
running this had not been achieved. This was found to be due to poor
temperature control and lack of adequate control software and a new
system was supplied to address these issues.
Ice build up on aircraft wing surfaces destroys the smooth flow of air needed for stable flight. The latest deicing technology uses electrically heated mats layered into composite wing edge components. To safeguard aircraft performance and safety every component needs to operate within strict tolerances and be tested and validated as fit for purpose.
A purpose designed thermal fatigue test rig provides high voltage insulation testing, heater and temperature sensor resistance tests and a programmed series of heater actuations at elevated supply voltage alternating with cold water being sprayed onto the part.
