Belt applicatiOn

For crossings with multiple pipes for the conveyance of
different services (for example, fluids and conduits), it is
possible to use different series of rings: a series of rings
for spacing the flow pipe and another series arranged as
a belt to fix the additional services.

the experts of RaCI’s technical department can carry
out a detailed analysis of the application and propose
the best solution for the specific needs.
