Romão Tecnologias’ Emergency Vents are essential safety devices for storage tanks with fixed roofs, designed to operate in emergency situations such as an external fire. In fire scenarios, intense heat can cause rapid vapor expansion inside the tank, leading to a sudden and dangerous increase in internal pressure. Without an adequate relief mechanism, this overpressure can result in tank rupture, with catastrophic consequences.
An Emergency Vent is a high-capacity pressure relief valve designed to open quickly and release large volumes of vapor or gas in the event of a sudden and severe overpressure, such as that caused by exposure to a fire. Unlike VAPVs, which handle operational pressure variations, Emergency Vents are sized for emergency events, ensuring that the internal pressure of the tank does not exceed safety limits during a fire.
Our Emergency Vents are designed and manufactured in strict compliance with ISO 28300 (Petroleum, petrochemical, and natural gas industries — Venting of atmospheric and low-pressure storage tanks). This standard establishes the requirements for the sizing and selection of emergency venting devices, ensuring that our products provide the necessary flow capacity to protect the tank in critical situations.
Romão Tecnologias’ Emergency Vents are built with robust and durable materials capable of withstanding the extreme conditions of a fire. Their optimized design ensures a quick and effective response when the tank’s safety is at risk.
Compliance with ISO 28300 ensures that our Emergency Vents have been rigorously tested and are proven to have the necessary flow capacity to protect the tank in fire scenarios, providing a level of safety validated by an international standard.
Designed to handle large volumes of vapor generated in emergency situations, our emergency vents ensure quick and efficient pressure relief, preventing tank rupture and the spread of fire.
Traditionally, some tanks used a fragile weld on the roof as a controlled rupture point in case of overpressure. Our Emergency Vents offer a more controlled, safe, and reusable solution, eliminating the need for complex repairs after an overpressure event and ensuring the structural integrity of the tank’s roof.
The robustness of the design and the quality of the materials ensure that the equipment will function reliably when it’s most needed, providing peace of mind to operators and safety managers.
