Important information The air has been completely suctioned out of the sealing pad to simplify shipping. However, the pad must NOT be stored in this condition. When you unpack the pad, put the venting nipple on the coupling to allow air to penetrate back in. That lets the pad obtain its normal cylinder shape again. If necessary, fill the pad with additional compressed air, but only to the point that it obtains its normal shape. The precondition for the safe use and the defect-free operation of Vetter pipe and test sealing bags is the knowledge and the observance of this operating manual as...

Pipe Sealing- and Bypass Bags Correct handling and usage Vetter pipe sealing- and bypass bags must, depending on the purpose of the task, only be inflated with compressed air to the corresponding pressure level using original inflation fittings. Inflation with inflation fittings from another manufacturer is classified as contrary to the regulations for correct use. They are exclusively used for blocking the intended pipes, for leak sealing testing of pipelines and for construction of a bypass. Any other application or use going beyond this is classified as contrary to the regulations for...

Pipe sealing- and bypass bags must be positioned full length in the pipeline and with the sealing area on the inside wall of the pipe. All pipe sealing- and bypass bags must be non-positively and positively positioned and fitted. Information about the dangers Changes and modifications to the sealing bags, inflation fittings and inflation hoses are not permitted. Operation of Vetter pipe sealing- and bypass bags are only permitted with original Vetter inflation fittings and inflation hoses. Parts made by another manufacturer can influence safety. Pipe sealing- and bypass bags are made of a...

Pipe Sealing- and Bypass Bags Operation of Pipe Sealing- and Bypass Bags This chapter informs you about which compressed air sources you can use with the Vetter pipe sealing- and bypass bags. Observe the corresponding pressure level with operation of pipe and bypass bags. 3.1 Operation with controller, inflation hose and compressed air bottle Note! In the following presented figures the sequence of events uses the pressure level of 1.5 bar as an example. The corresponding bags and accessories must be used for other pressure levels and other sources of air. Pipe sealing- or bypass bag 99...

3.2 Operation with controller, inflation hose and other compressed air sources Observe the maximum inlet pressure from the compressed air source for the different pressure levels (refer to the table below). Adapters in the adapter set The adapter set contains adapters for the following air sources: Truck compressed air connection and dummy coupling Close the control line with the dummy coupling. Local compressed air network Connection on the output coupling of a compressed air network. Truck tyre valve For inflation with a normal hand pump or foot pump. Truck tyre valve connection For...

Pipe Sealing- and Bypass Bags Hand pump and foot pump Hand pump or foot pump with 2 m connection hose to the connection onto the inlet coupling of a controller. Hand pump and foot pump do not belong to the delivery package of the adapter set. Operation with a foot pump 1.5 bar having a safety valve Foot operated air pump, 1.5 bar with safety valve and 2 m connection hose for inflation of sealing bags in connection with an inflation hose. Operation of Pipe Sealing- & Bypass Bags In this chapter you will find out how the Vetter pipe sealing- and bypass bags are applied. When using the pipe...

99 Draw the sealing bag to the support structure and inflate so that it can still be moved in the pipeline. 99 Secure the sealing bag with a securing line in order to avoid the bag slipping back when deflated. 99 The support structure should be made so that the sealing bag can be supported over a large area. 99 Leave the shaft and/or pipeline. 99 Make certain that no staff remain in the area of danger. 99 Inflate the sealing bag to the permitted maximum operating pressure from a safe position There is a danger of the bag catapulting outwards. The pressure or water column must be completely...

Pipe Sealing- and Bypass Bags Support suggestion for a pipe opening on the outside wall (presented as a diagram) 1 Outside wall with pipe opening The support structure of a pipeline under pressure must never be removed. Pipe sealing and/or bypass bags could suddenly catapult outwards. During a pressure test nobody is permitted to remain in the shafts or on and in the pipelines under pressure. 99 Vetter pipe sealing- and bypass bags are used in different pipe diameters (refer to the marking on the sealing bags). 99 Select pipe sealing bag, inflation hose, controller and air source. 99 There...

99 It is to be ensured that nobody remains in the shaft or pipe before emptying the pipeline. 99 Empty the secured sealing bag via the controller so the dammed liquid is able to slowly flow pass the sealing bag and support structure. 99 The support structure of a pipeline under pressure must never be removed. Pipe sealing- and/or bypass bags could suddenly catapult outwards. Construction of a temporary bypass Persons can be endangered by sudden inrushes of water, therefore an additional pipe sealing bag (2) must be installed in order to ensure the safety of the construction area. The safety...
