Short packers have a replaceable double-layer rubber sleevemounted on a PU tube.
All other parts installed in a packer are made of corrosion resistant materials.
On one side of the packer three wheels are attached at an angle of 120° to prevent tipping over while transported along the pipeline.
The effective packer length is 600 mm therefore they are suitable for repair of pipeline joints or repair of shorter pipeline sections along with insertion of stainless steel shells.
