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. Simultaneously, Hartmann is currently processing wellhead orders for Gasunie H2 testing phase 2 as well as for the first German hydrogen projects.
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. Design, assembly and tests are still carried out solely at the two locations in Celle and Burgdorf.
Within the scope of the jubilee, the brothers Werner, Martin and Christian Hartmann (from left to right), who now head up the company as the third generation, would like to thank their customers, partners and above all the close on 200 employees. Despite current restrictions, some activities such as culinary Markttage (industry information days) are planned on the factory premises or the planting of 75 trees. A development project will be raffled among the customers with the most demanding applications.All the information concerning the anniversary as well as a new company film are available online now.
Why the material selection and the manufacturing process are crucial with oxygen ball valves
With specially 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 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.
As with all Hartmann high performance valves, the oxygen ball valves can be deployed for high pressure ranges up to 420 bar and temperatures up to 550°C.
A new video clip on oxygen valves shows what’s important with the material selection and gives an insight into the individual production steps and application examples.
