Fire-fighting water, foam pumps, foam proportioning devices and pressure stabilization systems, remote control systems. Don’t fire-fighting facilities fall under the category of pressure vessels?
It does not belong. The medium does not fall within the scope of pressure vessels. Fixed and mobile containers with a maximum operating pressure of 0.1 MPa (gauge pressure) or greater for gases and liquefied gases, and liquids with a maximum operating temperature of equal to or higher than their standard boiling point; containers with a volume of 30 L or greater and an inner diameter (for non-circular cross-sections, this refers to the largest geometric dimension of the cross-section) of 150 mm or greater ； Gas cylinders, liquefied gas cylinders, and cylinders for liquids with a standard boiling point of 60°C or lower, whose nominal working pressure at full charge is greater than or equal to 0.2 MPa (gauge pressure), and whose product of pressure and volume is greater than or equal to 1.0 MPa·L ； Oxygen chamber.
Water foam does not belong; the medium does not meet the requirements
It is specified in TSG 21-2016
