Duct Integrity Tester (DIT) Market Expected to Witness a Sustainable Growth over 2018-2028

Valley Cottage, NY -- (SBWIRE) -- 05/28/2019 -- The growing demand from the telecom sector for DIT is fuelling the demand for the DIT market. DIT is used to check if the installed ducts are ready to use. DIT is performed to avoid improper coupling, missing out sections of duct, duct blockage, kinking, and others. Duct integrity tests are performed with the help of compressed air, mandrel, go-gauge sponge, and others. While performing DIT, the mandrel is pushed inside from one end with pneumatic pressure and is taken out from the other end. The three tests performed during the duct integrity testing are air pressure test, shuttle test, and sponge test. In the air pressure test, DIT is verified by injecting compressed air from one end of the duct to check if air comes out from the other end. Duct leakage is identified with compressed air by integrating the compressed air unit to one side to the duct and the pressure gauge to the other side of the duct. To identify duct leakage, compressed air is applied at the pressure of 10 bar at the first end of the duct for 10-15 minutes and is measured with pressure drop at the other end. If the pressure reading remains the same, then there is no leakage in the duct. If the pressure reading drops, it indicates that there is a leakage or a puncture.
