The array of storage tanks, surrounded by pipelines, showcases the implementation of safety measures such as breather valves to regulate pressure and protect against overpressure or vacuum conditions in the tanks

Flame Arresters

An image of a flame arrester, an essential safety device for preventing the propagation of flames in tanks and pipelines. The flame arrester is designed to mitigate the risk of fire by stopping the entry of flames into the system while allowing the passage of gases, ensuring a secure and controlled environment.

Flame Arresters (FA):


A Flame Arrester is an indispensable safety device employed in diverse industrial applications to safeguard storage tanks and vessels from potential flame propagation and explosion risks. These arresters are engineered to automatically intercept and extinguish flames, preventing any potential damage to the tank and ensuring the safety and integrity of the stored contents

Corsair Valve Services also specialises in the maintenance and calibration of breather valves from all brands, adhering to API 2000 and ISO 28300 standards, which also includes conducting a leak test. Other service providers may lack the necessary equipment for conducting leakage tests, leading to critical omissions during servicing. In addition, insufficient knowledge of industry standards such as API 2000, ISO 28300, and EEMUA 231 can result in inadequate servicing and testing. Therefore, when selecting a service provider to maintain your breather valves, it is crucial to ensure that they possess the appropriate expertise, equipmemt and adhere to industry standards in their service and testing procedures.

"How do they work ?"

Pressure and Vacuum Relief Valves, commonly known as Low Pressure and Vacuum Relief Vents, Breather Valves, Conservation Vents, or Tank Vents, serve a crucial role in safeguarding atmospheric storage tanks. They are specifically engineered to prevent over pressurisation or excessive vacuum conditions, as well as minimise the evaporation of tank contents into the atmosphere.

The need for pressure and vacuum relief arises in various situations, including:

  1. Displacement: When an atmospheric storage tank is being filled or emptied.

  2. Thermal events: Occurrences related to temperature changes.

  3. Fire conditions: Protecting the tank during fire incidents.

  4. Other events: Instances such as equipment failure that can impact tank pressure or vacuum levels.

These valves play a vital role in maintaining the integrity and safety of storage tanks by regulating pressure and vacuum levels in a controlled manner
