![]() ![]() This may not be specific to only pressure vessels but can reduce the damage in case there is fire because of the pressure vessels or somewhere else in the premises. ![]() Water taps and sprinklers: This is a must in most industrial facilities as it mitigates the risk of fire in general.Drainage vents: The industrial units where pressure vessels are used should have drainage vents.The unit where pressure vessels are used has to be protected with fire insulation. Fireproof insulation: This is an external feature, which helps reduce the spreading of fire and subsequent damage.Pressure outlet valves: These are not internal like the steam valves but can be incorporated in the industrial facility to release excess pressure and avoid subsequent explosion.This indicates the level of fluid in a vessel, thus preventing overflow and leaks. Fluid indicators: This is an inbuilt feature.Steam gauges help gauge the pressure of the steam within the vessel, whereas valves help release the pressure if it exceeds the preset limit. Steam gauges and valves: This is an inbuilt feature in the pressure vessel.Most of these features help the pressure vessel sustain a short fire without any damage. This helps mitigate fire and explosion risks. Pressure vessels used across industries, and especially the ones designed to hold volatile liquids and chemicals, are equipped with a few safety features. Incorporating Fire and Explosion Safety Features in Pressure Vessels Testing of pressure bearing capacity and mechanical strength: It is crucial to test the mechanical strength of the pressure vessel and its pressure bearing capacity according to ASME standards.These include magnetic particle tests, ultrasonic, and radiographic tests. Non-destructive testing (NDT) process: These non-destructive tests are carried out without disturbing the design.Incorporating inbuilt devices for protection: This is a regular part of the pressure vessel design, which includes safety valves and vents in the design.Only welders who clear ASME P1-F3 are qualified to carry out the welding for such pressure vessels. Quality of welding: The quality of welding should be as per ASME standards mentioned in their section 8. #Pressure vessel fire sprinkler design seriesNormally, they are made of carbon steel, nickel, stainless steel, 300 series & high temp SS, Inconel, aluminum, and more. #Pressure vessel fire sprinkler design crackMaterial used: The material used for making a pressure boiler should be robust and not crack under pressure.Hence, it is important to design a pressure vessel considering all the safety parameters: For end users of the vessels, it is important to ensure there are no cracks developed on the vessels after prolonged usage this could lead to leakages and explosion. When designing, it is mandatory for pressure vessel manufacturers to stick to ASME vessel design guidelines for the safety of workers and the overall industrial unit. Safety Parameters Considered During Pressure Vessel Design and Testing This post focusses on pressure vessel design, inbuilt safety features, and standards set by The American Society of Mechanical Engineers (ASME) and ISO. So, it is crucial that pressure vessel manufacturers incorporate safety features, including prevention of fire and explosion, when designing the vessel. This challenge increases, if volatile fluids or chemicals are stored in a vessel, as they may catch fire or explode at ambient pressures and temperatures. They have some inherent safety challenges due to the nature of their design and operation. Pressure vessels are closed tanks or containers designed to function at pressures higher than air pressure, usually 15psi, and hold gases or liquids inside at the required temperature. ![]()
