Pipe Plugs

Trelleborg Offshore and Construction’s Infrastructure Business, leading global supplier of polymer-based critical solutions for deployment in highly demanding infrastructure environments, has launched its innovative new range of pipe plugs which are lighter, safer and more flexible to install. Pipe closures for maintenance or construction work are a common occurrence in sewage systems, so it is important that they’re done quickly and efficiently to reduce delays or potential problems. In some instances, the pipe must be completely blocked off or the flow reduced. In these cases an inflatable stopper or pipe plug is ideal for the job. In increasingly more challenging environments with even tighter budgets, it is important that working pipes are stopped for as little time as possible and concerns over difficult or unsafe installations are diminished. Trelleborg’s new production process means that the plugs are no longer fully manufactured by hand, resulting in a higher consistency of quality control and the ability to ensure finite detail within each plug. Produced using layers of rubber reinforced with high quality Aramid, the material can now be applied more tightly so less fabric is required, resulting in a much lighter and more flexible product. With new side handles incorporated into the design, the plugs are now easier to handle and maneuver into position. In addition, the top plates are smaller in diameter, making transportation through tight manholes and difficult 90 degree pipe turns, much easier and quicker. The refined material application used within the new range will provide the plugs with an advanced ability to withstand high back pressures, significantly reducing any concerns of plug failures. The multi-size, inflatable flow stopper range is available for underground pipe diameters ranging from 40 mm to 2,400 mm and can be specified with, or without, a bypass. The improved designs are expected to decrease the time taken to install and remove the plugs, as well as improve flexibility and safety.
