发明名称 Chemical barrier plug assembly and manufacturing and dislodgement methods for hydrostatic and pneumatic testing
摘要 A barrier plug assembly for incorporation into a lower portion of a plumbing installation for supporting a column of test water during inspection of the installation includes a tubular plumbing segment for sealingly securing between and in fluid communication with opposing and spaced apart portions of a plumbing installation, the tubular plumbing segment being formed of plumbing segment material and having a plumbing segment interior and a substantially smooth and continuous plumbing segment interior surface; and a barrier plug having a plug upper surface and a plug lower surface, and having a plug circumferential surface adhering to the plumbing segment interior surface and extending diametrically across and sealing the plumbing segment interior until dislodged by a plug dislodgement triggering means; so that upon plug dislodgement the test water drains and the plumbing installation is operational.
