The first Hartmann wellhead for hydrogen well testing phase 1 was recently installed in the Netherlands. Our customer Gasunie is responsible to develop the national hydrogen infrastructure. Within the project, sustainable hydrogen will be stored at the Zuidwending underground gas storage facility. First, the existing wellhead equipment was comprehensively tested by Hartmann´s Material Suitability Test in order to prevent material fatigue and hydrogen embrittlement. In addition to the existing hydrogen suitable parts (green spool) Hartmann designed and manufactured new wellhead components including metal-to-metal sealing, API 6A ball valves. As part of the FAT a successful H2 test for leak-tightness was conducted at Hartmann.Read more
With the slogan “Together Towards the Future”, Hartmann Valves GmbH will this year be celebrating its 75th company anniversary jubilee.
Traditionally rooted in the oil and gas industry, the innovative family business provides ongoing support for its customers on the path to renewable energies such as geothermal or hydrogen. Based around the metal-to-metal sealing ball valve and special high performance valves the product range had expanded to the area of wellheads as early as the end of the 1990’s. As a globally active system provider, Hartmann today stands out due to its extensive consulting, the development of individual customer solutions and commensurate range of services.
Why the material selection and the manufacturing process are crucial with oxygen ball valves
With specially produced designed oxygen ball valves by Hartmann Valves, oxygen plants and oxygen pipelines can be reliably shut off and safely operated. With regard to the increased fire and explosion hazard, only metals and metallic and sealing materials are used in the process which are suitable for the demanding oxygen medium and are tested accordingly. A stringently specified production process guarantees oil and grease-free manufacture.
Managing director Werner Hartmann explains the technical and commercial advantages of using ball valves instead of gate valves at the wellhead. It will be demonstrated how Hartmann ball valves lead to higher safety, reduced environmental impact, increased plant availability, minimized maintenance effort and thus lower operational costs. The video shows the comparison by means of […]Read more
Hartmann special ball valves assure safety in gas turbine applications worldwide. For the Siemens turbines SGT5-4000F (V94.3A) and SGT5-2000E (V94.2) and Ansaldo turbines AE94.3A and AE94.2 standard shut-off or special designed multi-way ball valves are available as reliable combination with different actuators. They are implemented for diverse services with the media fuel oil, fuel gas, […]Read more
In addition to special hydrogen ball valves and wellheads Hartmann Valves now also offers material suitability and hydrogen leak-tightness tests for challenging hydrogen (H2) applications. Reliable shut-off valves, the right material selection as well as standardised pressure tests help users to increase the operational safety in existing and new hydrogen application areas. Durable special Hartmann […]Read more
In order to enable safe and reliable shut-off even at temperatures below -100°C, Hartmann has developed various ball valve designs with construction features and materials suitable for low temperatures. Soft sealing valves often reach their limit when the main seal between ball and housing (seating) fails. The soft material contracts at low temperature and as […]Read more
Successful changeover: The Xmas tree with ball valves Within the scope of overhauling several Xmas trees for gas production, a completely new design of construction was decided on: In the place of Xmas trees with gate valves, solid block Xmas trees with integrated ball valves have already been in operation at several North German locations […]Read more
At the 37th Celle Wasa run on the 10th March 2019 many of the blue-and-white “Hard” men, women and children were once more on route at the double through the town centre. “Hard” in the truest sense of the word – as the 30 or so participants didn’t shy away from the adverse weather conditions […]Read more
Since the start of 2019 Peter Wegjan has been overseeing the areas of chemical, petrochemical and plant construction at Hartmann Valves and advises customers on ball valve shut-off solutions for special application fields. As a chemical engineer he has experience in sector-related sales and management both home and abroad and was active over many years […]Read more
