Abstract:
A pressure test cap assembly for use in pressure testing a piping installation including a pipe and comprising:(a) a cylindrical mounting wall sized for insertion into and sealing engagement with a pipe, said mounting wall defining a cap axis extending axially therethrough; (b) a closure disc removably connected to said mounting wall and cooperating therewith to seal a pipe when said mounting wall is positioned in sealing engagement with the pipe with said closure disc connected thereto, said disc having an inner disc surface and an opposite outer disc surface; (c) said closure disc having a peripheral rim which is cylindrical about said cap axis and includes an inner rim portion projecting axially inward from said inner disc surface and an outer rim portion projecting axially outward from said outer disc surface; and (d) said closure disc being connected to said mounting wall by said inner rim portion in such a manner that impacts of a selected strength to said outer rim portion, in a direction substantially parallel to said cap axis, are operative to rupture a connection of said closure disc to said mounting wall to thereby enable removal of said disc from said mounting wall.
