Webb3 okt. 2014 · After hydrostatic testing, it is essential that all piping be thoroughly dried with inert gas (e.g., nitrogen) or dry air having a dew point of -40 F or below. The dew point of the air or gas leaving the piping must be checked and drying continued until the dew point is at or below -40 F, which may require quite some time. WebbTESTING 1. Hydrostatic testing of piping designed for internal pressure The minimum hydrostatic test pressure at any point in the system shall be as follows. - Not less than 1-1/2 times of the design pressure. - For a design temperature above the test temperature, the minimum test pressure shall be as calculated by the following equation.-S 1.5 ...
