MDF has been found to be the best sheet material for use as a compression packer on the ends of jacking pipes due to its resistance to compressive load, and its thickness recovery if the load is removed.
12 mm thickness
The packers are normally manufactured in segments, with the number per joint ring dependant on the size of pipe – 3 No per ring on a 450mm dia. to 6 No per ring for a 2100mm dia. pipe.
