With minimal input required, instantly compute the required length of restrained joint pipe for each and every bend, dead end, inline valve, tee and reducer that is plausibly available for the selected pipe diameter. Automatically calculates results for both BARE pipe and POLY-wrapped scenarios. A unique aspect of this calculator is the user’s ability to override the typical default soil density of the backfill and presume a static line pressure against newly installed valves, thereby leading to more realistic results.

Basic Data

Soil Condition

Values indicate minimum total lengths of restraint pipe required in feet on each side of fitting or other appurtenance. Where requirements of adjacent fittings or devices overlap, use the greater value to extend restraint past lesser fitting needs.
