Quick question came up recently on the 1 piece in building risers. Typically we have seen contractors provide thrust blocks at the bend. We've had one installed recently without one and the foundation was poured before we were able to view it. The contractor is advising us that a thrust block is not needed. The specification sheet provided advises:
If the piping installation is essentially complete, the piping restraints may adequately take the thrust loads generated by having a blind end on the pipe system. In these cases, no special actions to restrain thrust or side loads are required, and the fitting installed in the system may be adequate for hydrostatic testing. Is the restraint at the pipe connection on the supply side all that is needed?
