Rausch Pressure Testing


Joint Testing

Pressure test system for single joint tests from 200 – 600 mm (Patent No.DE19740276).

The tests can be carried out either by air or water; the test sleeves are separately filled. Packer pressure, variable 1,5 – 4,5 bar; test pressure selectable up to 500 mbar.

This pressure test system consists of the control unit PREMUS 600, supplemented by the respective Kampac test packer according to the pipe diameters. A pan and tilt camera is integrated inside the packer. Between the two packer sleeves, is a Plexiglas which allows the camera a 360°view of the pipe for accurate positioning and optical control of the joint during the tests.
The Kampac packer is connected to a crawler and thereby driven to the joint to be tested. The controls, i.e. the pressure transmitter is connected directly at the packer and operated through a magnetic valve. Therefore, the pressure is measured directly at the packer which results in the fact that the volume of air inside the hose doesn’t have any effect on the measurement


Section Test

  • Pressure testing system PREMUS 600 with test packer Vario-Kampac for testing of pipe sections and branches respectively laterals up to 5 m long from 200 – 600 mm mainline
  • Variable test range through use of telescopic rod
  • Pan and tilt camera with sealing plug for positioning of packer and of lateral plug as well as for monitoring and documentation

Detailed Method Statement:

The Vario-Kampac has two test plugs, connected via a telescopic rod for leak tests up to 5 m distance with one end having a packer together with a pan and tilt camera. Similar to our satellite systems, there is a special adaptor for a flexible or spring-loaded connection to the main camera. At this connection, the lateral sealing plug is fixed; which is then accurately positioned through the movement of the pan and tilt of the camera as well as through the maneuvering of the crawler.
With the M- series the plug can be positioned up to 5 m into the lateral
The entire positioning process is observed by the camera and once accurately positioned, the packers in the main line and the sealing plug in the lateral will be filled with compressed air, after which the tests will be started using the appropriate test pressure.
The Vario-Kampac system is equivalent to the joint test system therefore the test reports are also issued with the Rausch software PipeCommander.

The lateral has been sealed by a sealing plug and the house connection can now be tested using a plug at the house side entry provided the relevant equipment is available.

The PREMUS control unit in combination with Vario-Kampac can also be used with water for the pressure test of joints, branch connections and laterals. Since a large amount of water would be required to fill the test sections for laterals it is recommended to use external water supply, i.e. hydrant or flushing vehicle.
