McDonald & Ross Const. Ltd. has over 34 years of experience in testing and drying pipelines. We either have the equipment necessary or access to the equipment required to test pipelines with whatever media is required. Most of our experience is with air and water. We have equipment such as chart recorders, dead weights, a range of certified test heads, a range of pig launchers and receivers, air compressors and drying units and a dew point tester to -42 deg. celsius. With the use of our 20,000 square foot shop we have the ability to test indoors if it is required or necessary due to the weather.
