Pipeline Protection from Seismic and or Gradual Soil Subsidence

FLEX-TEND® Flexible Expansion Joints

FLEX-TENDS are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced (seismic) or the gradual motion of soil subsidence (settlement).

The double ball FLEX-TEND joint provides shear relief for connections to structures with its ability to offset in any plane. This is accomplished by the use of two ball and socket pairs separated by an expansion joint. As the offset motion occurs, the expansion joint provides the required increase or decrease in length, thus relieving axial strain on the line and structure. This configuration has been used successfully on connections to tanks, buildings, bridges, and other structures.

Pipeline Protection from Expansion Contraction

EX-TEND® Expansion Joints

EX-TENDS are linear or axial expansion joints for water or wastewater pipelines. They protect pipelines from the stresses of thermal expansion/contraction. There are many applications but the most widley used to protect pipelines on bridge crossings where the pipeline is exposed to year long seasonal changes.
