Standard Flow Liner
Liners are used to prevent flow induced vibration or erosion caused by abrasive materials. When lateral movement is required in the expansion joint, the flow liner diameter must be reduced to provide clearance.
Drop-in liners are used when conditions require frequent replacement. This type of liner can also be furnished in a telescoping configuration. Gaskets are required on both sides of liner face to effect a seal. Sometimes called a top-hat liner....
Telescoping liners are used on short expansion joints with large axial movements. When fit close together, they can also be used in systems where the flow can be in either direction....
Removable covers are required on flanged expansion joints in order to tighten the bolts during installation. They also can be removed for inspection purposes. In the event of a leak or failure, the shroud can help to deflect the steam or other media....
All shrouds help to protect the bellows from damage. This type of cover is used when removal of the shroud for installation is not necessary. DME welds the cover in place after the expansion joint has been inspected and pressure tested....
Tie rods are used to restrain the thrust forces created by the internal pressure of the expansion joint. Normally the system anchors are used to withstand the thrust forces....
