The value of (good) flanging in drainage channels

  • Quality and transportability are two essential elements for a performing, long-lasting drainage system. Both factors depend on how the system is flanged
  • Flanging can be used in drainage systems for channel splitting, transport and reassembly
  • The flanges are perforated stainless steel plates that connect the various channel sections
  • Reassembly with flanges: gasket or silicone? We use silicone, which keeps channels watertight and long-lasting. It also ensures that the drainage system is 100% stainless steel, benefiting hygiene
  • Inoxsystem® has developed a truly advantageous flange system: the delivered material comes with stainless steel fixing screws and transparent silicone for the flanges, allowing the full channel length to be assembled as a whole.

Connection

There are multiple fundamental aspects and variables to consider when implementing a drainage system. In particular, two elements are extremely important: quality and transportability. The connection (in the true sense of the word) between these two factors is the flange. Let’s find out more.

The strength of stainless steel

When talking about flanging and drainage system quality, the first essential factor is the material used to produce the channels, drains, syphons and various elements.
At Inoxsystem® we always work with AISI 304 and AISI 316L stainless steel. Compared with galvanized steel and other materials, stainless steel offers multiple advantages. Specifically, it guarantees:

  • hermetic sealing
  • durability, thanks to its anticorrosion properties

In addition, stainless steel is optimal in terms of hygiene, an important aspect for indoor drainage systems or those in high-sterilisation environments.

Flanging and drainage systems “on the road”

A second element to consider is how easily the drainage system can be installed when it reaches the worksite.

Regardless its destination is in Italy or abroad, the drainage system must be divided into parts for transport, and must also be easy to reassemble upon arrival at the worksite.

This is where connection flanges come into play. With them, the channel can be divided into sections, transported to the worksite, and then reassembled. Our channels, which can be 10 metres or just as easily 100 metres long, are divided into sections of 3-6 metres for delivery according to the transport order.

The connection flanges are perforated sheets that guarantee an extremely hermetic result when applied. They are the most delicate part of a drainage system, which requires special attention during production and installation.

Reassembly with flanges: gasket or silicone?

Drainage channels can be reassembled in various ways. The most common one involves inserting a gasket between the two flanges, which are then fixed using screws and bolts.

Even though this technique certainly speeds up installation, with the gaskets absorbing the impact that the various sections are subjected to, it does have some disadvantages, including:

  • gaskets are not made of stainless steel, so they can nullify the aesthetic result of the channel and become an area where bacteria grow
  • gaskets can deteriorate over time, compromising drainage system efficiency

To solve this problem, Inoxsystem® has developed an advantageous solution in terms of both hygiene and performance: the two flanges are connected using a special transparent silicone. During channel assembly, this high-performance sealant is applied over the whole surface of the flanges to enhance adherence. The silicone is supplied to the worksite personnel directly by Inoxsystem®, along with the drawings and all the accessories required for installation.

Flange to the highest standard

By replacing the gasket with silicone, we can guarantee a result that is completely tight, highly aesthetic and long-lasting. Using flange in this manner ensures that the drainage system is 100% stainless steel. Finally, each flange is tailor-made, following the characteristic of the internal channel slope. They can be adapted as required by the worksite and the special requests of clients
