Design and Analysis of Hydro Test Rig for GGCB Forged Valve with 4 Stations

Abstract

Hydro testing as the name suggests using water as the working fluid. It is used to detect leakages present in the valves such as Gate, Globe, Check and Ball valves (GGCB Valves). The water is used as testing as well as working fluid which gives the exact results. Since water is incompressible it can be pressurised at high pressures without significant change in its volume. Valve to be checked is subjected to the high pressure when it is clamped to the hydro test rig. The pressure for testing is verified by the ANSI standard used for manufacturing the valve. It includes two types of leakage tests namely 'body leakage test' and 'seat leakage test'. The main components of hydro test rig are design by theoretical method and the same design is checked by finite elemental analysis method using ANSYS 15.0 software.
