Plugco - Model PTP -Inflatable Pneumatic Pipe Test Plug - Sewer Pipe Plug

Material
That plugs are made from SBR+NR mixed rubber, nylon cord, Kevlar cord and strong fabrics.

Dimensions
These plugs are available  in many different sizes ranging from 30 mm to 2000 mm.
These plugs are available in many different pressure ranging 0,2 to 6,0 bar.

Application
Pipes and circular tubes blocking the line to stop flow.

Inflatable rubber pipe plugs are used during maintenance or new production of pipe systems. They are used for pipe sealing and sewer sealing, as well as concrete water pipe testing, pipeline joint testing, leak pressure testing, and general pipe maintenance. Two of the challenges in pneumatic pipe plug design are to increase the working pressure and to design a rubber pipe plug that can be applied in a wide range of pipe diameters.

Model designation is Pipe Test Plug (PTP). It is totally same as Pipe Plug (PP) model except that includes bypass connection. 

Pipe Test Plug (PTP) connection allows water filling inside pipe line if there is no manhole access to pipe line or Pipe Test Plug (PTP) connection can be used for bypass the flow and discharge to another line with a circulating pump.
