Thrust Block

What is a Thrust Block

Definition of Thrust Block in Construction

The term thrust block refers to any type of element that will absorb, or take the thrust that occurs when a liquid is forced through a conduit system. For example a water line that is installed underground, will exert substantial force on any joint or turn of direction in the piping or conduit system. Liquid when flowing in a contained system will push on the opposing wall of the system when the flow of the liquid changes direction. This force on the opposing wall will push the system against this joint or change in direction. If the conduit system is not supported with what is referenced as a thrust block, then would be a chance of the entire system shifting and being compromised. To ensure that this thrust does not incur damage to the piping or conduit system, thrust blocks are installed at the joints and change in direction. In most cases, these thrust blocks are constructed of blocks of concrete, which are poured in strategic locations, to absorb the thrust of the liquid as it changes direction. Mechanical engineers will engineer the location of these required thrust blocks as required. The proper placement of the thrust blocks on a piping system is extremely important to the proper functioning of the system, without any damages incurring, due to the pressures exerted by the liquid flow within the piping system.
