Technology and Capabilities
Bigger. Heavier. More complex. That’s exactly what we are built for.
Big challenges call for industrial solutions. At its Deggendorf site, DWE develops and manufactures reactor systems, pressure vessels, and special components in dimensions, weights, and material combinations that only a few manufacturing sites worldwide can master. The combination of engineering, in-house manufacturing depth, large-part machining, and decades of experience enables the economical realization of even the most complex apparatus and plant components.
Manufacturing processes
The scope of services covers the entire manufacturing process, from plate working to final assembly. This includes cutting, rolling and special forming, welding, Post Weld Heat Treatment (PWHT), machining, deep-hole drilling, large-scale milling, and surface treatments up to electropolishing. For thick-walled parts, large-format components, and demanding special materials, specially designed manufacturing, lifting, and heattreatment capacities are available. Thanks to the close integration of engineering, manufacturing, and quality assurance, even unusual geometries and the highest technical requirements can be realized reliably.
Sizes and handling
DWE manufactures components up to 12 m in diameter, 80 m in length, and 1,500 t in piece weight. Dimensions like these require not only manufacturing areas and crane capacities on a corresponding scale, but also the experience to handle components of this size dimensionally accurately and without damage across every manufacturing step. This ability to safely master the weight and dimensions of even the largest single components is one of the foundations of DWE’s profile. The site’s integrated logistics options make a key contribution here: with its own Danube port, rail connection, and heavy-load infrastructure, even exceptionally large and heavy components can be transported directly from the manufacturing floor.
In-house manufacturing depth at a single site
From cutting, forming, welding, and machining to heat treatment, testing, and documentation, manufacturing comes together at a single site. This depth keeps control over every manufacturing step in-house — from the delivery of the material to the finished, tested component — and avoids the interfaces at which quality and schedules are otherwise lost. Manufacturing is complemented by extensive large-scale machining capacities, deep-hole drilling technology, and heat-treatment facilities for demanding pressure equipment and special materials.

Welding technology and materials
Welding is one of the central manufacturing disciplines at DWE. All essential welding processes are performed in-house and backed by several hundred active welding procedure qualifications to the AD code as well as Welding Procedure Specifications (WPS) to ASME. The combination of comprehensive materials expertise, decades of manufacturing experience, and high-performance manufacturing facilities enables the production of demanding apparatus and reactors for the chemical and process industries.
Plasma and flame cutting, as well as carbon-arc gouging
Large-scale and mechanical machining
Separate stainless-steel production
A dedicated, physically separated production hall is available for stainless steels and special materials. This separation prevents iron contamination and is a prerequisite for components with the highest demands on cleanliness, vacuum tightness, and magnetic properties. This applies in particular to applications in chemicals, vacuum technology, research, and the nuclear and fusion sectors.
