Nominal Diameter: 50 1500mm Working Temperature: -196 1300 Working Pressure: 0.11.0MPa A flexible combination of stractures,comprises of a bellows tube,2 end tubes fit for connection into pipeline,and thermal insulation materials,etc.Generally used to compensate the axial displacement in straight pipeline.Pressure thrust (blind plate force) can not be restrained by rods on this type ,but it must be restrained by the main anchor supports at both ends of pipeline.
