Standard installation and maintenance process of EI45 fireproof duct

PROPER INSTALLATION AND MAINTENANCE PROCESS OF EI45 FIREPROOF AIR DUCT

EI45 fireproof duct is one of the important solutions in the ventilation and air conditioning systems of civil and industrial works, especially in places with high requirements for fire prevention and fighting such as high-rise apartments, commercial centers, factories, hospitals, etc. Proper installation and maintenance not only ensures operational efficiency but also plays a vital role in ensuring fire safety. The following article will analyze in detail the process of installing and maintaining EI45 fireproof duct according to standards.

1. OVERVIEW OF EI45 FIREPROOF AIR DUCT

EI45 fire-resistant ductwork is a type of ductwork designed to withstand fire for a minimum of 45 minutes, with the ability to prevent the spread of fire and smoke through the air duct system. The symbol “EI45” represents the ability to withstand heat (E) and insulation (I) for 45 minutes.

Outstanding features of EI45 fireproof duct:

  • Use galvanized steel material, with fireproof insulation layer.
  • Has the ability to prevent fire spread and prevent smoke effectively.
  • Easy to construct, install and maintain.
  • Meets national and international fire protection standards.

2. INSTALLATION PROCESS OF EI45 FIREPROOF AIR DUCT

Step 1: Survey the current status of the project

  • Evaluate construction site, ceiling height, installation location.
  • Determine the route of the air duct, the location that needs fire protection (over the floor, through the wall, etc.)
  • Prepare detailed design drawings, based on fire prevention and fighting standards.

Step 2: Prepare materials and equipment

  • Fireproof air duct EI45, accessories (elbows, elbows, valves, flanges, hangers...).
  • Fireproof materials such as glue, ceramic fabric, heat-resistant tape, etc.
  • Construction tools: drill, cutter, welder, lift...

Step 3: Duct processing at the factory

  • Cut, shape and assemble air ducts according to design drawings.
  • Check dimensions, tightness, fireproof coating.
  • Packed and transported carefully to the construction site.

Step 4: Construction and installation at the construction site

  • Install the hanging frame and bracket firmly in the correct design position.
  • Mount the duct in the correct direction, tightly connected with flanges and heat-resistant glue.
  • Construct wall and floor sections with specialized fireproof materials.
  • Ensure tightness, no air leakage, no size deviation.

Step 5: Inspection and acceptance

  • Check the entire system according to fire prevention standards.
  • Pressure test, check the tightness and strength of the air duct.
  • Record of installation acceptance report.

3. MAINTENANCE PROCESS OF EI45 FIREPROOF AIR DUCT

Regular maintenance helps detect damage and wear early, ensuring the efficiency and longevity of the EI45 fire-resistant duct system.

Step 1: Make a regular maintenance plan

  • Maintenance frequency: minimum 6 months/time or according to manufacturer's recommendation.
  • Assign personnel, prepare equipment for testing and repair.

Step 2: Check the overall system

  • Check the duct cover and fireproof layer for peeling or rust.
  • Check the firmness of the hanging frame and the connection between the pipe sections.
  • Measure air pressure, check air flow to evaluate performance.

Step 3: Cleaning and Repair

  • Clean dust and impurities inside and outside the air duct.
  • Repair and replace leaking and damaged sections.
  • Add fireproof layer if needed.

Step 4: Record keeping and reporting

  • Make inspection report, system status report.
  • Propose improvement options (if any).
  • Keep records for periodic inspections or fire safety inspections.
