    HDPE pipe can be bent to a radius 25 times the nominal pipe diameter (Example: 12” HDPE can be cold formed in the field to a 25ft radius). This can eliminate many fittings required for directional changes in a piping system where fittings and thrust blocks or restraints are required with alternate materials.

    Thrust blocks, however, are not without limitations. It has been argued that thrust blocks are the cheapest form of pipeline restraint. When all of the costs such as labor, forming time, and waiting for concrete to be poured and cure are added to the price of the concrete, the thrust block is not as cheap as originally thought.
