How to understand fire protection requirements? 10.1.1.5 When the process imposes fire protection requirements on control valves, cable penetrations through walls or into gaps in electrical cabinets and panels shall be provided with fire-resistant isolation seals when such requirements apply. In areas with fire protection requirements, the packing for control valves should be made of metal or flexible graphite. 7.2.2 The material for cable trays can be galvanized carbon steel, aluminum alloy, or stainless steel ; When fire protection requirements are in place, fire-resistant cable trays should be used; in applications with such requirements, the gas supply pipelines for instruments should be made of stainless steel
Fire protection requirements refer to the demands for fire safety design and protective measures for buildings, facilities, equipment, etc., as stipulated by laws or relevant standards. In engineering, fire protection requirements typically involve aspects such as material selection, the installation location of equipment, the handling of cables passing through walls, the design of control valve stuffing boxes, the material used for cable trays, and the choice of gas supply lines for instruments. In areas with fire protection requirements, fire-resistant sealing measures must be applied at the points where cables pass through walls or enter electrical cabinets and panels, in order to prevent the spread of fire in the event of a fire ; The packing gland structure of control valves should use metal or flexible graphite packing to reduce the risk of fire ; When fire protection requirements apply, fire-resistant cable trays should be used to enhance fire resistance ; In applications where fire protection is required, the gas supply pipelines for instruments should be made of stainless steel to enhance their fire resistance. In summary, fire protection requirements are designed to ensure the fire safety of buildings and facilities, prevent the occurrence and spread of fires, and safeguard the lives and property of people. .
The fire protection requirements for automatic valves are derived from the PSI document of the piping discipline.
