CT&T uses the best possible technologies to identify and pinpoint the location of leaks in single and double wall tanks or pipelines. Leak location detection can significantly reduce the expense of repairs by localizing excavation to the leak and avoiding digging up an entire tank or pipeline.
Enhanced Leak Detection
MDleak® Enhanced Leak Detection (ELD) is a third-party certified chemical marker/tracer testing method used to certify containment to a leak rate of 44 gallons per year (0.005gph). Current state regulations for leak threshold allow 876 gallons leaked per year (0.1gph) and remain compliant. Not only does MDleak® prove that a containment is tight, but if there is a leak the technology will identify its location to allow repairs with a minium amount of downtime. MDleak® ELD testing can be used to certify and identify leaks in both primary tanks and pipelines to soil, as well as to identify the leak location from a primary pipeline to the secondary or interstitial space (+-2% of the pipeline length). Technicians determine the appropriate chemical marker and concentration to use based on the fluid of vapor within the vessel and the surrounding environmental conditions. The method allows the customer to dictate the leak rate for the application. Customers can require leak rates from 0.1 gph to a more critical environment where extremely small leak rates are required, such as 0.0000001gph.
Helium Leak Location
Helium is an inert gas and one of the smallest gas molecules. Therefore, it provides an excellent tool for locating leaks in the unfilled portion of underground storage systems. More economical to use than chemical marker testing, helium leak locating is CT&T's first choice in applications where it is most likely to provide a definitive test. CT&T uses specialized technologies tuned to detect helium along the tank or pipeline and pinpoint the location of the leak; minimizing the amount of the system requiring excavation to complete repairs. Helium leak testing can generally be between one thousand and one million times more sensitive than pressure decay techniques.
Acceptance/Commissioning New Construction
Precision leak detection should be a part of your pre-acceptance testing for all new construction and upgrades. Whether installing a cross country pipeline or upgrading a gas station, precision leak testing (0.005gph or 44 gpy) ensures that you receive a “tight system” and the contractor builds to the highest standard.
