Conical Round Tubes - Preliminary Tests for Use on Lighting Columns

Abstract:

Conical pipes belong to a group of economical profiles, which find broad application in various metal products. Until now the conical pipes are manufactured by following methods: rolling on two-high mill in impressions with varying depth on the rolls perimeter; forging in lever swaging machine, formation in combined process of drawing and rolling, and rolling on skew rolling mill. Manufacturing of conical pipes belong to complicated engineering processes, and used until now methods do not allow to meet demand for conical pipes – 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 with till now known methods. It seems that the process of conical pipe envelope formation will allow to wide conical pipes assortment.
