Tests for Newly Laid Pipes | Water Conveyance | Water Engineering

In this article we will discuss about the hydrostatic and leakage tests performed for newly laid pipes. Hydrostatic Test: After laying the new pipe line, jointing and back filling, it is subjected to the following tests: (i) Pressure test at a pressure of at least double the maximum working pressure-pipe and joints shall be absolutely watertight under the test. (ii) [...]
