This is Carl Hamm
Röhrenwerk Kupferdreh Carl Hamm GmbH from Essen is a fourth-generation mid-sized family business with over 90 years of experience in underground and surface mining. The company manufactures high-quality steel piping systems for water and wastewater management, the energy industry, tunnel and well construction, building services and mining. Core competencies are welding and pre-assembly work as a certified welding specialist company, corrosion protection and coatings, finishing, design and development, as well as documentation and logistics. A patented development is the tension-resistant push-fit coupling ZSM, used as casing, pump line or pressure line up to 200 °C, with axial total loads up to 2,000 tonnes free-hanging, at depths of up to 1,600 m and in dimensions from 3" to 16" (system up to 52"). Since 1987 the company has also manufactured geotechnical equipment such as drive core samplers and offers testing systems as well as DGUV inspections. The company is a system supplier to RAG and a strategic partner of RWE and works on current topics such as vertical piping for geothermal energy and H2/carbon capture cavern storage.
