They are special elements designed to absorb large impacts in the piping due to seismic phenomena or other circumstances like water hammers.

   During the normal operation and movement of piping, they do not restrict movements, offering minimal resistance. However, when a sudden impact occurs, they lock themselves becoming highly rigid supports, protecting the system against that event. They can be installed in any position with relation to the pipe by the use of special beam attachments, highly rigid clamps and special enlargement pipes.
