Small leaks are best left to LDT crews to pinpoint and have repaired, instead of the <br /> contractor spending hours looking for little leaks. <br /> 5. Fast identification and leak location substantially reduces repair cost. <br /> General: <br /> 1. Extraction plugs should be installed and sealed properly <br /> 2. A construction crew shall be onsite during the test period. This crew should be equipped to <br /> repair any portion of the system. <br /> 3. The MDleak® method can test piping containing liquids. However if a liquid is present <br /> additional time and cost will be incurred. <br /> Product Piping: <br /> 1. The contractor shall have all shear valves plug or capped using steel not plastic fittings and <br /> connected to the piping. <br /> 2. It is best to complete the turbine connections before the Pretest. Locating and repairing <br /> fittings within the tank sumps during the pretesting is more efficient and less confining than <br /> during the final testing. <br /> 3. Primary piping should be under test pressure when LDT arrives onsite. <br /> Secondary Piping and Connections: <br /> 1. MDleak®_ does not require special fittings to be installed by the contractor. <br /> 2. The contractor should use standard approved factory secondary termination fittings or <br /> boots. <br /> 3. Secondary piping should be under test pressure when LDT arrives onsite. <br /> 4. All termination secondary fittings shall include test ports. Test ports shall be accessible to <br /> the LDT Technician. <br /> Vent Piping: <br /> 1. Extraction plugs should be installed and sealed properly <br /> 2. Vent risers should not be caped and the contractor should be capable of working on the top <br /> of the vent risers. <br /> VR Piping: <br /> 1. Extraction plugs should be installed and sealed properly <br /> 2. VR piping at the UDC should also be caped or plug using steel not plastic fittings. <br /> Author Da%id Rabb 2of 2 <br />
