Flow stopping provides you with the opportunity to isolate a section of your pipeline whilst essential repair and maintenance work is carried out. This method uses a drilling to create a hole in the pipe line whilst under pressure, then a plugging head or bag is lowered in to the pipeline to stop the flow of the product.
For PE pipelines a bag or a squeeze off is used. A squeeze off uses the plastic of the pipe to make the seal once the pipe is squeezed flat this can be carried out on MDPE, HDPE and other plastics.
