How do I choose the right brush(s)?
Selecting the right brushes for tube cleaning can often make the difference between successful and unsuccessful cleaning. Not only is it important to choose the right material, but also the amount of hair (strands) and the excess.
When all these factors have been properly selected, a successful cleaning can be carried out. Below are the various issues and the corresponding explanations/answers:
1. Nylon or Stainless Steel?
This depends on 2 factors:
- Type of material tubes.
- Type of contamination.
Nylon basically works in 9 out of 10 cases. Because this is a hardened type of nylon with a HEXA shape, you can often use it to remove even the most coarse dirt. With Nylon you also have no risk of scratching your pipe(s).
Stainless steel is often used when working in a stainless steel pipe and/or when heavy pollution is present in the pipe(s). Sometimes nylon can just not provide the desired cleaning effect, then stainless steel is the next step to use.
2. How many hairs (strands) do I need?
There are basically 3 different possibilities:
- 4 beaches
- 10 beaches
- 18 beaches
This indicates the total number of bristles present on the brush. At the top of the page an 18-wire spider brush is shown. In principle, this in turn depends on a number of factors, for example: what is the pipe diameter and what is the contamination.
If too few hairs are used, the cleaning effect may sometimes diminish. too many hairs and you have too much torsion, which may cause the hose to interfere with the drive again. In principle, 18 beaches are hardly ever used. This is because too much torsion is often released.
- 4 strands is almost standard with stainless steel brushes. This is because, the 4 strands can then rotate faster and create more friction. More than 4 strands with stainless steel brushes is not recommended.
- 10 strands is almost standard with Nylon brushes. This is often the perfect intermediate size and sits on a ''sweet spot'' when it comes to creating friction for the pollution, and not too much torsion for the hose.
The table below is useful to stick to for the right amount of beaches:
|Tube diameter I.D.:||Possibilities Beaches:||Material Possibility:|
|50 - 100 millimetres||4 beaches||Nylon and stainless steel|
|100 - 200 millimetres||4, 10 or 18 beaches||Nylon and stainless steel|
|200 - 400 millimetres||4, 10 or 18 beaches||Nylon and stainless steel|
|400 - 600 millimetres||4, 10 or 18 beaches||Nylon and stainless steel|
|600 - 800 millimetres||4, 10 or 18 beaches||Nylon and stainless steel|
Selecting the right excess is most important. Spider Brushes work best with a good excess. This allows the hairs to completely scrape the pipe. This is because the brushes do not clean with the tips of the hairs, but with the entire surface. Because of this, cleaning with spider brushes is often much more effective than with other brushes.
You can find the correct excess by using the following calculation:
- Tube diameter inside x 1.5 or x 2 = size correct spider brush.
For pipes over 100 millimetres, we always recommend the brush x 2.
