reinforced aluminum sealing tape
- How to install and run flexi pipe to plenum box:
First, according to the executive plan, we estimate the required dimensions, then we cut the hose flexi pipe to the desired dimensions with scissors or a cutter (carpet cutting blade) and put it around the collar. In the next step, we put the steel belt buckle in the desired place and secure it with a special lock. In this way, the connection is established on one side and the other side is done in the same way until the channeling work is completed.
- Advantages and characteristics of flexible hose pipe channel:
1- Very high speed in installation and execution (saving time):
Due to its extreme flexibility (flexible duct) and very light weight, the implementation of STI flexible duct with thermal and antibacterial insulation (aluminum flexible channel (foil)) or aluminum hose channel for air transmission (spiral channel - hose channel for air transmission hose) )) is very convenient and easy.
2- Very high speed in repair and reconstruction:
In case of damage to a part of the flexi channel (flexible pipe hose channel) of air transmission, it is possible to restore and repair the desired part easily and without spending any extra cost.
3- Ease of cutting and running the flexible duct:
Insulated flexible pipe, combi or combi flexible channel and STI aluminum (spiral flexible channel) with a simple tool such as; Scissors, cutters, and carpet cutting blades can be cut, while cutting and bending old and traditional galvanized channels requires special and specialized tools.
4- Low cost for preparation, installation and implementation:
The price of flexible channels is much more suitable compared to other materials available in the market, and from the length; It is 1000 t to 50.000 t. For example, the price of flexible combi "8" is about 10,000 t and the price of insulated flexible "8 is about 10,000 t. It is 20,000 t.
The installation and implementation of these channels is less expensive because the flexible channel or air transmission hose pipe channel does not need to be bent, shaped, etc. and only needs to be connected to the relevant collar with a lock. And for example, for the implementation of one meter long hose channel, an amount of around 10,000 t is calculated and intended.
5- Has thermal insulation inside the body Hose: pipe with glass wool and polyester insulation, flexible channel or combi pipe and aluminum (flexible foil pipe) flexible STI with elastomeric thermal insulation such as pipe insulation, IFD, glass wool and polyester (air transmission hose channel or air transmission hose pipe ) because it has thermal insulation in itself, it no longer needs to be re-insulated, which is economically very economical compared to old and traditional galvanized channels, because galvanized channels need to be installed and implemented after purchase. and after implementation, in order to save energy, glass wool insulation should be used on its outer surfaces, which will increase the final cost and also lose time.
6- No formation of dew on the duct body.
7- Reducing the pressure drop of the flexible duct:
Due to the circular cross-section of this type of air transmission channels (hose pipe channels) and also their flat and smooth surface, they have a much lower pressure drop compared to square channels.
8- Minimal energy loss (due to the insulation in the air transmission hose channel)
