Sampling holes

Sampling holes can be drilled directly along the pipeline.

These holes must be made perpendicular to the axis and in the direction of the radius of the pipe section.

It is necessary to carefully remove any shavings or other residue caused by work.

The diameter and position of the sampling holes can be calculated by means of the FA/STUDIO software or they can be determined using the pre-calculated tables (refer to the appropriate manual).

The sampling holes must be positioned away from strong air currents such as, for example, those generated by air vents.

The identification of the sampling holes along the pipes can be made easier by using the “Aspirating point” labels (LABEL23X10).

Capillary kits (CAPKIT2510SR) can be used to dislocate the sampling point with respect to the aspiration line.

Several examples of application are:

  • need to conceal the pipeline inside a false ceiling or similar

  • protection of the gaps between ceiling beams

  • surveillance of an object (electrical panel, rack of electronic devices, etc.).

In these cases, the sampling holes must be made in the centre of the terminal of the capillary kit.
