Fire protection standards for air ducts according to QCVN 06:2022/BXD | Sao Viet Air Duct Manufacturing Workshop

The latest fire protection standard for fire-fighting ductwork is QCVN 06:2022/BXD.

In high-rise buildings, shopping malls, hospitals, factories, and industrial parks, fire-resistant duct systems are a crucial component of fire protection solutions. Although... Fire resistance certification (EI) While the overall system is evaluated, the quality of ductwork fabrication is a fundamental factor determining its ability to meet the project's technical requirements.

For M&E contractors, choosing a The manufacturing facility has the capability to perform precision machining according to drawings and technical standards. This will help reduce installation errors, save time, and support the acceptance testing process.

What is the EI rating on a fire-resistant duct system?

According to current standards, the index EI It demonstrates the fire resistance of a structural element over a specific period of time.

  • E (Integrity): The ability to prevent fire from penetrating.
  • I (Insulation): The ability to limit heat transfer to the other side.

Common fire resistance ratings include:

  • EI30
  • EI45
  • EI60
  • EI90
  • EI120

The required EI level will depend on the fire protection design specifications and the installation location within the building.

The role of the production workshop in a fire-resistant duct system.

Many people believe that simply using fire-resistant materials is enough for a system to meet EI standards. In reality, the quality of workmanship in the factory directly affects the final product of the system.

A properly manufactured product should ensure the following:

  • Precise dimensions according to the shop drawing.
  • Low error rate, making installation easier.
  • The tightness of the joints meets the design requirements.
  • Flanges and matching accessories.
  • The material surface must meet the required standards before being coated with fire-retardant material.

Incorrect sizing or structural errors in fabrication can increase construction time and incur on-site adjustment costs.

What are the requirements for duct systems according to QCVN 06:2022/BXD?

Depending on the function and location of the system, the design documentation may require:

  • Smoke extraction system.
  • Staircase pressurization system.
  • Fire-fighting ventilation system.
  • Fire-resistant piping that penetrates walls or floors.

In each case, the system may need to meet different EI levels such as EI30, EI45, EI60, or EI120.

For the manufacturing workshop, the task is to fabricate the air ducts according to the drawings, using the correct materials and technical requirements provided by the design unit or contractor, creating the foundation for the completed system to meet acceptance requirements.

The capacity of the production plant determines the project's progress.

For large-scale industrial or construction projects, production capacity depends not only on machinery but also on quality control processes.

A professional manufacturing facility needs to meet the following requirements:

  • Machining according to shop drawings.
  • Modern CNC cutting and forming machines.
  • Control the size and quality of each batch of products.
  • Matching accessories, flanges, and connecting components.
  • Ensure that delivery schedules are met as planned by the contractor.

This helps construction units reduce on-site processing time and minimize issues arising from dimensional discrepancies.
