12. Allowable Joint Deflections. - WSSC Water

Part One, Section 12. Allowable Joint Deflections Water DESIGN GUIDELINES 2008 12. Allowable Joint Deflections. a. General. 1) When it is necessary to deflect pipe from a straight line in either the horizontal or vertical plane, the amount of Joint deflection shall not exceed the Allowable Joint deflections as shown in Tables "3", " ", "4", " ", " ", " ", " " and " ". Figure "A" illustrates the Joint deflections shown in the tables. The deflections listed in the tables are the maximum deflections Allowable for wssc pipeline designs and should not be exceeded.

crowns of the different diameter pipes. For sewer pipelines larger than 27-inch diameter, with 12-inch and smaller laterals entering the manhole, design the laterals by matching the invert to or above the crown of the larger pipe to prevent flow from the larger pipe entering the smaller pipe. Determine hydraulic losses to verify the design.

working pressure of the PVC pipe should be limited to 96 psi (235 psi -139 psi =96 psi). The manufacturer’s published pressure class for a PE4710 DR 17 pipe is 125 psi. The allowable total pressure during surge is 187.5 psi ( 1.5 X PC =1.5 X 125 psi). The allowable surge allowance is 62.5 psi ( 187.5 psi – 125 psi).

Pipe agrees with this rule of thumb and recommends that the maximum working pressure for PVC Schedule 40 and PVC Schedule 80 fittings is 60% of the maximum working pressure of pipe of the same diameter and schedule. As with pipe, the maximum working pressure must be de-rated at temperatures exceeding 73 degrees F.

plant output; increased operating pressures increase pipe wall thicknesses, which, in turn, increase piping stiffnesses further. Such increased operating temperatures applied on “stiffer” systems increase pipe thermal stresses and support loads. So, it is all the more important to make the piping layout flexible at the time of routing.
