Abstract. Conical pipes belong to a group of economical profiles which find broad application in various metal products. Manufacturing of conical pipes belong to complicated engineering processes, and the existing methods do not allow for the demand for conical pipes to be met– especially the long ones with large crosswise dimensions, e.g. pipes for lamp posts. This situation makes it reasonable to look for new processes with wider engineering possibilities when compared to the existing methods. It seems that the process of conical pipe envelope formation will allow for a wide conical pipes assortment.
