Tube and pipeline construction

In the tube and pipeline construction technical brushes basically have the following functions:

- Treating weld seams
- Deburring cutting edges
- Removing the coating of pipelines (Cut Back)
- Pipeline service / pigging

Weld seam treatment
While welding, residues occure which need to be removed before the following welding process.
LESSMANN pipeline brushes are specially developed for professional use on U- and V-welds in the pipeline industry. The remarkable features of the high quality LESSMANN pipeline brushes are the long lifetime and the quietness of running. They are especially narrow and therefore they are the perfect tool for cleaning all welds at tube conncections.
LESSMANN pipeline brushes are available in different models and with different filling materials. Also encapsulated brushes or brushes which are right-left knotted are available.

Deburring of cutting edges

When producing or processing tubes, after the cutting process burrs are generated which need to be removed with LESSMANN brushes.
In deburring machines which are equipped with wheel or roller brushes, the tubes turn around its axis while it is transported. Thereby the brushes catch all deburring edges in the inner and outer area of the tube and remove the burr completely or round it defined.

When deburring cutting edges manually usually bench grinders are used.

Removing the coating of pipelines (Cut Back)

For removing the coating of pipes, usually several rings of knotted wire brushes are mounted together to get one massive block of wheel brushes. Diameter of the brush, wire thickness and the overal shape of the brush are defined by the size of the tube, the material oft he layers and the cut back machine in use.

Pipeline Service / Pigging

In the pipeline industry and tube service LESSMANN interior brushes are used to clean the interior of the tubes.
For internal cleaning of pipelines special brush constructions are used, depending on the different demands.

Pipelines for e.g. crude oil have to be cleaned in the interior at regualar intervals because of the crude oil which is heated for the transport. Due to the heated oil paraffin wax is segregated and settles down at the interior of the pipelines.Regularly the tubes are tested for cracks, therefore the paraffin wax and other residues have to be removed.

Also for keeping the output of the pipeline constant it is essential to have a clean inner side of the tube.

Tubes with small diameters can be cleaned with interior brushes, wich are available in different measurements and with different filling materials.
