A renowned chemicals group faced a tricky challenge: They needed a pipeline for acidic exhaust air (NW 300) which would combine low weight, chemical resistance, vacuum resistance and diffusion tightness. For safety reasons, welding work could not be carried out on the existing plant.
with maximum surface protection
Our basic program of glass lined pipeline elements covers the nominal sizes DN 25 to DN 600 with standard lengths of up to 3 m depending on the nominal size.
According to customer requirements, our pipelines can be coated with any type of enamel from Düker Email Technologie. They are therefore particularly suited to carrying acids and alkalis, abrasive fluids and very hot, highly corrosive media. They are corrosion resistant, tend to resist adhesion, have a high level of purity, are easy to clean and show catalytically inert behavior.
The outside of our pipeline parts is coated in a zinc dust primer for corrosion protection. Upon request we cover all corrosion protection classes according to DIN EN ISO 12944 (corrosion category C1-C5), such as also nickel or zinc plating.
In addition to an extensive range of standard pipeline elements, we can also offer our customers innovative new developments, like our new Duo Safe Flange DSF and individually customized constructions that fulfil the most complex requirements and withstand the highest demands.
Current case studies
A technology leader in the chemical industry was due to renovate their tetraethyl silicate manufacturing plant. The large-scale project included significant replacement investments in the area of highly acid-resistant enameled pipelines and columns.
