Test Procedure for Horizontal Pipes (i.e. not probes)

This test procedure is appropriate for detecting major leaks in short lengths of small diameter pipes.

1. In this procedure, the creep in polyethylene is sustained by maintaining the selected test pressure for a period of 30 minutes.  This is achieved by additional pumping during the initial 30 minute period.

2. The pressure should then be reduced rapidly from the system to a nominal pressure of approximately 2 bar at which point the control valve should be closed and the system isolated.

3. A record should be made of the pressure readings at the following intervals:

• Every 2 minutes for the first 10 minute period
• Every 5 minutes from 10 to 30 minutes
• Every 10 minutes from 30 to 90 minutes

Within a 90 minute period a good indication will normally be achieved as to the integrity of the pipe section.

If during the 90minute period there is a falling away of pressure, this would indicate a leak within the system.

4. The resulting graph for a leak-tight system should have a characteristic profile similar to that shown in the following diagram.
