Gate valve bonnet failures from thermal expansion of fluids at high temperature - In a steam-assisted gravity drainage application, immediately after start-up, a gate valve bonnet failure caused a release of pressure to atmosphere. In thermal applications throughout the oil and gas industry, there have been incidents of valve failures during start-up. Resulting damage can include stretching studs and loss of pressure integrity between the body and bonnet. The main cause is pressure build-up in the gate valve cavity from thermal expansion of fluids, which was completely full and isolated. Such pressure exceeded the rated working pressure of the valve.
