KE® Rubber DFS-Type Expansion Joints all engineered products are designed to the actual specificationsfor:• Movements• Temperature• Pressure/pressureloads• Media• Neutralisingaxial,lateral,angularand torsional forces• Vibrations,pulsationandfriction• Misalignment• Externalappliedloads• Corrosiveenvironment

Pressure and temperatureAs standard KE® Rubber Expansion Joints are de-signed with polyester reinforcement fabric. For ap-plication where high temperature and high pressure

occur at the same time, alternative high temperature rubber(HT)andreinforcementfabriccanbeused.

Tie rodsExpansion jointsextend in lengthwhenpressurized,andmustbeconstrainedwithintheirratedlength.Theforce generated by this internal pressure is described as “The Pressure Thrust”.Where the pipe supportsand anchors are not designed to absorb this force, tie rods across the joint must be specified.

Total movementIt is important that the total of static and dynamicmovements does not exceed the rated movement capability specified for the joint. Where the dynamic movement frequency and amplitude are high, the joint pressure rating should be reduced in proportion.

Pressure loadsKE® Rubber Expansion Joints can be designed to withstand pressures of up to 1600 kPag. They canbe engineered for even higher pressures if desired, depending on the combination of operating tempera-ture, movement and pressure, caused by operating equipmentorprocessesinthepipingsystem.

ProtectionPulp and paper

Pressure balanced

KE® Rubber Expansion Joints can be designed as hoses for special pipe systems, such as pulp and paper plants. Rubber hoses are in-stalled in the part of feed pipes which transports the pulp to the paper making machine.

Rubber hoses must be completely smooth at the in-side surface, in order not to stop the flow of the very fine particles in media. Rubber hoses are designed up to1000kPagandcanabsorbmovementsof±100mm axial.

In-line pressure balanced expansionjointsabsorbsaxialmovementand/orlat-eral deflection while restraining the pressure thrust

onthesystem.Thisisachievedbymeansoftiede-vices interconnecting the line bellows with outboard compensating bellows that are also subjected to line pressure.

Each bellows set is designed to absorb axial movement and the line bellows will usually absorb lateral deflection. Pressure forcesare not generated in a piping system with expansion joints, when this construction is used as the volume changesinthepipingsystemareofequalvalue.

Pressure balanced expansion joints are employedwhere the location of the expansion joint prohibits or makes it expencive to install main anchors.
