Industrial services for refineries, power plants and the chemical industry

Hoffmann Piping and More GmbH is a company founded in 2023 in Cologne, specializing in assembly and service work in piping construction, steel construction and vessel construction. The focus is on complete piping prefabrication, including the integration of weld-in valves and other technical equipment – supplemented by contract welding, the application of wear-protection layers and the complete assembly of complex plants. In a dedicated prefabrication hall, steel structures, piping and industrial components are produced under controlled conditions. The company accompanies projects from work preparation and shutdown planning through execution to commissioning, including acceptances and complete documentation of all work steps. Core industries are refineries, petrochemicals and chemicals as well as power plants and energy supply; there the company also carries out shutdown and turnaround work as well as maintenance and inspections. Customers include, among others, Raffinerie Heide GmbH; together with partner ERMO-Rohrer/Rohrer Industrieservice, the company was awarded the Performance Award of Raffinerie Heide for shutdown work in autumn 2025.
