The manufacture of BUTTING’s longitudinally welded stainless steel pipes has formed the basis of the company’s product line. The joint development of technically demanding and high-quality products also counts among BUTTING’s range of services. Together with their customer Krones, they have brought an annular tube boiler for bottling plants into mass production. Recently the company has been able to deliver the 150th annular tube to the group. As early as 2004, collaboration began with Krones AG, which designs, develops and produces machines and plant for bottling and packaging technology at its main site in Neutraubling, Bavaria. In place of the cast iron boiler used to date, the prototype of an annular tube boiler was developed by Krones and BUTTING as the central container for the collection and subsequent direct bottling of foods. The container body is completely flange-free, so that maintenance work to change seals etc. is no longer necessary. Besides the reduced maintenance requirements, a further advantage lies in the rapid and simple cleaning of the tube geometry. BUTTING manufactures and supplies the complete system element for Krones: from pipe manufacture and shaping through welding and mechanical finishing to surface treatment as well as testing and acceptance activities, all work steps are carried out at the production site in Knesebeck. The range of sizes of the available rings here ranges from 1800mm to 5400mm in diameter.
