Abstract

UOE pipe manufacturing processes influence directly on pipeline resilience and operation capacity. At present, most spread pipe manufacturing method is UOE. This kind of manufacturing process is based on cold forming principle. To avoid appearance of unwanted effects, the need to know the level of strains resulted after every technological step appeared. For this case a manufacturing process by using special designed equipment is simulated. The experimental simulation presented in this paper is performed for L 415MB (X60) steel plate with 7.9 mm thickness and a width of 1250 mm. As a result a DN 400 (16 inch) pipe is obtained. Manufacturing process is monitored by Digital 3D Image Correlation System Q-400 and the principle of operation is based on Digital Image Correlation.
