Rubber- pneumatic plugs

 

Rubber- caps are used to shut off water, sewer and storm water pipelines with diameters from 100 to 2800mm , repair , technical inspection , removal of blockages and leakage control . They can be installed through manholes or special holes for pipes. When you install the pipe plug give a compact form , is lowered into the pipe and filled with compressed air to the working pressure specified in the data sheet . Incrementally the cap tight to the walls of the pipe , securely cover it. After repair of the deflated plug and remove it from the pipeline. Specifications plugs are shown in Table 1.

CHARACTERISTICS OF RUBBERIZED FABRIC PNEUMATIC PLUGS  

Rubber- caps are made of several standard sizes to cover the pipes of various diameters. Manufacturing of plugs with bypass ( straight-through connections) .

Rubber- caps are made of durable synthetic fabric , rubberised airtight layer of chloroprene , has good resistance to weathering , open flames , abrasion, low temperature, alkalis, acids, oils , and good ozone resistance . Additionally, the plug supplied with special O-rings made ​​of porous rubber for better sealing of the pipeline.

Rubber- caps are resistant to acids and alkalis , which is very important when working in the wastewater. Hydrocarbons contained in the effluent without prejudice to the stubs , even if they remain in the sewers for a few days. The plugs can be used in a temperature range from minus 30C to plus 50C .

 

ADVANTAGES OF USING RUBBERIZED FABRIC PNEUMATIC PLUGS PRODUCTION "NPP " SIBREZINOTEHNIKA "

- Provide secure overlapping of different forms of sections of pipelines

- Easy and quick to install and remove a small diameter wells or the holes in the pipe

- One unit covers different diameters

- Long service life

- Light weight

- Compact

Another advantage of the design of these caps is maintainability . In case of damage caps , such as sharp objects present in the reservoir , they are easy to repair ( repair manual attached to the cap) . After properly carried out repairs rubberized plugs can be used again as new .
