By-Pass 0.5 Bar Stoppers

By-Pass Stoppers

The By-Pass Stoppers offer a very versatile way to conduct work within pipelines. By-Pass Stoppers can allow flow through them whilst making a 0.5 bar seal to the inside of the pipes, with the use of Bauer fittings the flow can be maintained while work is carried out in the dry.

If the pipe fall is great enough one By-Pass Stopper can be used in conjunction with lay flat hose to ensure that the flow continues away without filling the chamber to be worked in. On shallower falls a By-Pass Stopper in either side of the chamber can be joined together using Bauer fittings and either armour core or layflat hose.

The By-Pass Stoppers can also be used for over pumping, as shown in the working drawing below.

  2. Blank Stopper braced in case the by-pass fails
  3. Blank Stopper to ensure the over pumped flow does not flood the workforce

With the addition of different end caps water tests and air tests can be performed on a variety of large diameter pipes.

The stopper size you require is simple to work out for instance a 500-1200mm will cover all pipe sizes from 495mm to 1200mm and so on.
