Inflatable Pipe Stoppers

· Designed for sealing sewers, drainage systems, pipelines, and gullies.
· Mainly used during the technical support to repair and to fix the sewers/pipelines/drainage systems/gullies, fixing accidental
issues
· Purposed to be suitable for use in sewers/pipelines/drainage systems/gullies leak locating and testing with air or water. They
are used with PLUGLINE Inflatable Test Plugs as a set to perform tests via the EN 1610:2015 Standard.
· Adequate and suitable for use on testing the pipes in accordance with EN 1610:2015 Standard.
· Made of high-quality special NR/SBR rubber reinforced with kevlar tire (lighter, tougher, and more puncture-resistant) cording.
This material can be changed with NBR, CR, EPDM materials according to customer and application requirements.

· Available for pipe diameters from 35 mm (1,37") to 4200 mm (165,35").
· These Stoppers are Pneumatic Stoppers, they can be called Pneumatic Ball, Standard inflating/working pressures of PLUGLINE
Inflatable Pipe Stoppers are specified as 1,5 Bar (21,75 psi) and 2,5 Bar (36,25 psi).
· In addition to these pressures, Inflatable Pipe Plugs have higher working pressures like 6,0 Bar (87,02 psi) and 12,0 Bar
(174,04 psi) can be produced and they are named as PLUGLINE Inflatable High-Pressure Pipe Plugs.
· Usable for temperatures from -40 °C (-40 °F) to 70 °C (158 °F).
· Providing have high resistance to chemicals.

What is the Meaning of Back Pressure?

Backpressure is the maximum pressure for the stopper in the pipe can hold on to the pipe or do not slip in the pipe.
The needed information about backpressure is that 5 meters of water height in the pipe causes 0.5 Bar backpressure.
For this example, the stopper must have a 0.5 Bar back pressure specification so it can hold on to the pipe.
