How to seal the pipes when installing smoke curtain?

We often see various pipes in areas such as underground parking lots, including pipes for transporting liquids (water, gas, steam, etc.) and cables. These pipes usually need to be passed through the installation site of the smoke curtain. If we do not carry out reasonable blocking during the construction process, it will inevitably become a safe passage for the spread of fire accidents. Therefore, effective blocking measures should be taken to block them. So what are the reasonable blocking measures? Let's follow the steps of Hai'an County smoke curtain manufacturer Saduqi Door Industry Fire Safety to learn more about it!

What kind of material is used for smoke curtain to pass through the pipe?

The smoke curtain completes the design of the smoke partition of the building by isolating the flow of smoke. The smoke curtain can also improve the actual effect of the smoke exhaust system of each air outlet. It must be made of flame-retardant materials such as thick steel plate and laminated glass, and its installation methods are divided into two types: movable and mobile. The movable smoke curtain is controlled by temperature sensors, smoke detectors or other control systems during a fire.

For smoke barriers that need to pass through pipes, the smoke barriers are generally made of movable steel or fireproof cloth materials. The steel materials are made of thick steel plates, and the fireproof cloth is made of flexible silicone rubber fireproof cloth. These two materials are convenient for drilling and passing through the pipes in the basement of the villa.

When there are many pipes in the construction of smoke curtain, it is troublesome to install hard fireproof plates or steel smoke barriers to pass through the pipes, so soft plastic flexible smoke barriers are generally used to pass through the pipes.

The movable flexible smoke barrier is mainly composed of left and right rail decorative strips, buckles, and fireproof silicone cloth. It is easy to install and pass through the pipes.

If it is required to install a movable smoke barrier due to the particularity of the project. For the movable smoke barrier, we can only try to ensure the minimum volume, and then leave as little gap as possible between the pipe and the ceiling for installation.
