Obtained for deformation of the pipe to cold by means of matrix to fixed beam 400/800 with inner spirit to the pipe during all the manufacturing process maintaining constant the section of the bending. We generally obtain therefore a perfect product for pneumatic transport used in the fields molitoria, plastic, passage fluid and air. We realize and we supply on ordinazione also small amounts of diameters and types of bending
Thickness tolerances like table UNI. Constructive characteristic : straight feature in departure and arrival of 300 mm approximately ( adapted for splices)
