Industry Solutions for Apparatus & Valve Manufacturing
In apparatus and valve manufacturing, components such as valves, flaps, pumps, shafts and pressure vessels operate at their limits. Flowing media, high pressure and fluctuating temperatures place a permanent strain on components. Corrosion forms on sealing surfaces, flowing media erode material, and in many cases both stresses act simultaneously.
The result is leaking joints, damaged seats and, in the worst case, complete component failure. For pressure-bearing components, this is not only costly but also a safety risk.
We supply wear protection solutions, spare parts and welding consumables that address exactly these issues and keep your components in service longer.
Typical Welding Defects and How We Avoid Them
A welded joint in apparatus and valve manufacturing is only as good as the way the process is controlled. Two defect patterns occur particularly often, and both can be reliably avoided with the right approach.
Problem: Cracks Caused by Incorrect Heat Control
If a component is heated unevenly or cools too quickly, the microstructure and residual stresses change. The weld becomes susceptible to cracking, which can lead to failures in heavily stressed components.
Our Solution: Controlled Heat Management
With preheating and coordinated welding parameters, we keep residual stresses low and reduce the risk of cracking.
Problem: Leaking or Defective Welds
Defective welds lead to leaks and therefore to component failure. In pressure-bearing components, there is also a considerable safety risk.
Our Solution: Clean, Standards-Compliant Execution
Careful processing with documented quality ensures the weld remains leak-tight and suitable for approval.
Suitable Welding Consumables for Valves, Pumps and Pressure Vessels
Wear protection in apparatus and valve engineering only works when it matches the component. We select wear protection, welding process and filler material according to the application, depending on the medium, temperature, pressure and dominant wear type. For aggressive media we use corrosion-resistant overlay layers; against erosion we use wear-resistant alloys. If both stresses occur simultaneously, we combine these properties in a coordinated layer solution. The types of wear below take you directly to the suitable welding consumables for the respective application.

Our portfolio ranges from housings, shafts and rotors to flaps, slides and nozzles. In addition, we supply mixer linings, mixer tools and mixing paddles, as well as mills and ploughshares. We also machine and deliver pipes and pipe bends, screws, drum linings, wear rings and rotary valves. Here you can find suitable wear and spare parts for your systems:
Fully Automated Hardfacing and Additive Manufacturing
In the Laser Competence Centre, capilla brings together modern technologies for coating and component manufacturing.
Here, components are specifically tempered, wear-resistant layers are applied and complex components are manufactured using additive processes such as 3D cladding.
This enables solutions that go beyond classic welding applications and make components sustainably more capable.

capilla Wear Protection Based on Bulk Material Specification
We do not work with standard recipes. Whether bulk material, medium or workpiece, what matters is always the actual load acting on the component. Grain size, hardness, temperature, flow or chemical aggressiveness determine which type of wear dominates and which protection really fits.
Before we define the welding consumable, process and layer structure, we analyse the operating conditions. This produces a solution that fits your component. Tested consumables and defined parameters are part of this, supplemented by standards-compliant documentation for safety-critical components.
Frequently Asked Questions About Wear Protection in Apparatus and Valve Engineering
If you have your own welding capacity and the component is non-critical, the right consumable from our range is sufficient in many cases. For pressure-bearing components, complex geometries or applications requiring documented quality and standards-compliant execution, we prefer to take on the complete job, including process selection, heat management and inspection.
The most effective approach is corrosion-resistant overlay layers whose alloy is matched to the specific medium. What matters is not only the choice of welding consumable but also the processing. A clean, controlled weld ensures that the layer retains its protective effect over a long period.
Depending on the component and task, we work with MMA, MIG, MAG or TIG. For more demanding overlay layers, PTA and laser cladding are used. This range allows us to choose the process to match the application – from a simple joint weld to a high-quality cladding layer on a sealing face.
The right alloy always depends on the interplay of medium, temperature and pressure. For strongly corrosive applications we frequently use nickel-based alloys; for abrasive flows, wear-resistant hardfacing layers are used. For combined stresses we combine the properties so that the layer meets both requirements.
For pressure-bearing components, a defective or leaking weld can mean not only component failure but also a genuine safety risk. Weld quality here is therefore not a "nice-to-have" but a prerequisite for component approval. We work accordingly with documented quality and standards-compliant processes.
Yes, this is possible and in many cases more economical than a new part. The prerequisite is standards-compliant execution with a suitable welding consumable and documented quality. Worn or damaged areas are restored by targeted hardfacing without the component losing its approval.
The most important factor is heat management. It influences the microstructure, residual stresses and therefore crack susceptibility. With preheating, controlled welding parameters and coordinated cooling, the risk can be significantly reduced – a factor that determines the service life of critical components.
Concrete figures always depend on the component, the medium and the operating conditions. What is clear, however, is that with adapted welding technology and an optimised welding consumable, service life can be significantly extended – and with it the time between two shutdowns.
Our range extends from housings, shafts and rotors through flaps, slides and nozzles to mixer linings, mills, pipes and pipe bends. Screws, drum linings, wear rings and rotary valves are also among the components we regularly machine and supply in apparatus and valve manufacturing.
