Constant Supports

These are spring supports with constant tension devices throughout the whole length of the piping. They are used under conditions where the effort on the piping are critical and the pipes are subjected to greater movement than ½” during the thermal expansion and contraction cycles. Likewise they are used on places where no transfer of forces to critical connections or to other supports can take place.

Construidea's® constant tension devices in 84 sizes in each of the 7 standardized types with load capacities up till 22,000 kg. They cover piping runs up till 500 mm.

In order to obtain a longer lifetime under aggressive environmental conditions the finishing of the Construidea® constant tension supports offers the maximum anticorrosive protection during the production stage a hot galvanization immersion process on its components, as well as a dust recovering, either a resin covering with neoprene on the springs is applied, according to the ASTM norm A-153.

Each of the Construidea® constant tension supports is tested and calibrated in our plant for the specific conditions for which it was designed and the corresponding certificate of the applied tests and an operation warrant is supplied upon delivery.
