Webbursting disc device or designated for site joints can lead to uncontrolled leakage etc. 6. The service life and bursting pressure of a bursting disc is affected by various conditions such as corrosion, fatigue, creep or physical damage during handling or operation. Any of these may cause failure and, as such, the bursting disc life cannot be WebBackground. A bursting disc protecting the seawater side (shell side) of a high pressure (HP) gas intercooler suffered a low pressure (LP), in-service failure. This resulted in an uncontrolled flow of seawater into a platform flare system. The intercooler had two pairs of bursting discs each with inter-disc space pressure sensors and tell-tale ...
