The weld between pipes (gas, oil pipelines) requires that there is no possibility of cracks in the weld.
To avoid this problem is necessary to add a big amount of material on the weld.
Each addition of material generates scale on the weld which has to be brushed off without getting rid of the material from the previous weld. Pipeline wire brushes (Mod. CPL) are used for that particular brushing purpose
These brushes have some unique characteristics as high performance, design, higher quality components, etc…
