Why Perform a Hydrostatic Test on a Storage Tank? - Elite

Why Perform a Hydrostatic Test on a Storage Tank? Following completion of a new storage tank,one of the final mechanical tests recommended is a hydrostatic test.The first and most obvious reason to fill the tank with water is to ensure the tank has no leaks.The tank is filled with water at a prescribed rate and then examined after 24 hours to ensure there are no cracks,pinholes,or other discontinuities inWelding on API 650 Tank after Hydrotest ! - Mechanical This hydrostatic test of the tank shall be conducted before permanent external piping is connected to the tank.Attachments to the shell defined in,located at least 1 m (3 ft) above the water level,and roof appurtenances may be welded during the filling of the tank.[u]After completion of the hydro-test,only non-structuralWelding after Hydrotest - AST Aboveground Storage Tank Nov 05,2007 welded storage tanks Temporary Openings after Hydrostatic Test#0183;shell defined in,located at least 1 m (3 ft) above the water level,and roof appurtenances may be welded during the filling of the tank.After completion of the hydro-test,only non-structural small attachments may be welded to the tank in accordance with Hydrostatic Testing Requirements
