BUTTING manufactures stainless steel vessels, tanks and columns according to customer specifications in several sections or in one piece, through a very large degree of prefabrication in the plant.
In March 2016, BUTTING obtained the order for the production of two columns. This processing engineering equipment in the form of a hollow, slender column had special fittings. Both columns were prefabricated in Knesebeck – the first column, 25metres long and 1 400mm in diameter, was produced in two parts, as was the second column, which was much smaller, 15metres long and 1 000mm in diameter.
The large number of fittings presented a special challenge: A total of more than 190metres of welding wire had to be welded for the inner fittings. The columns left Knesebeck at the end of February in several parts on a total of four lorries. The very high degree of prefabrication benefited the customer. The joints did not have to be welded, but only screwed together on the construction site.
