About us
Over 60 years of experience
In 1952, Waldemar Korupp founded a plumbing and electrical installation business in Twist, Germany. In the mid-1950s, natural gas and oil fields were developed a region called ‘Emsland’. As result of this, we decided to shift our business activities to the oil sector and natural gas industry.
Firstly, electrical work was carried out on feed pumps and treatment plants. After this, the Waldemar Korupp GmbH has specialised in cathodic corrosion protection.
In 1992, the management was handed over to Waldemar Korupp Junior, who is running the company with great success to this day. Thanks to our knowledge in the field of cathodic corrosion protection, our customer base is growing in Germany and abroad.
