Technical features and purpose of DIN 86089 concentric reducers
The DIN 86089 standard defines the design parameters, geometric dimensions, and manufacturing requirements for concentric reducers used for butt welding in piping systems. These fittings are intended for the correct diameter change of pipelines in lightweight structures manufactured in accordance with DIN 86019 requirements. The primary material used for the production of these components is the corrosion-resistant copper-nickel alloy CuNi10Fe1,6Mn (material grade 2.1972).
The use of reducers made from CuNi10Fe1,6Mn alloy ensures high resistance to seawater, aggressive media, and high temperatures, making them indispensable in shipbuilding, desalination plants, and the chemical industry. Specialists at EV Group China guarantee strict adherence to geometric tolerances and the chemical composition of the alloy according to the current revision of the standard.
