Tapered poles manufacturing cycle

Pipe cutting

The manufacturing process of Tecnopali tapered poles begins with the tube that is cut to size obtaining pieces of different diameters.

Shaping the ends of the tubes

In line with the cutting operation, the ends of the pipes are cold shaped in order to allow the coupling between the pieces of different diameters pipe.

Circumferential assembly and welding

Then, pipe sections are assembled together and subjected to circumferential welding by means of automatic and manual welding procedures. The welds are done in compliance with specific processing techniques (WPS) in compliance with the UNI EN ISO 15609-2 standards and adopting qualified procedures (WPAR) in compliance with the UNI EN ISO 15614-1 standards. All welding workers are qualified with a license according to the UNI EN ISO 1418 and 287-1 standards.


At the end of the welding phase, the tapered poles are subjected to specific processes at the base (eg slots) and at the tip (eg calibration).


Each tapered poles manufacturing process stage is subjected to constant quality control by the employees who work under the supervision of Tecnopali Quality Control Office Manager.
