Francisturbine coating – a 2.5 mm (100 mils) thick elastomeric coating with MetaLine 785 serves as the OEM coating ex works from the turbine manufacturer and protects this turbine impeller. Why elastomer? Because no other material offers greater resistance to the constant alternation of pressure and tension in cavitation!
Francis turbine impeller coating – when it comes to turbines, everyone talks about efficiency, i.e., surface smoothness. But then the competition uses so-called ceramic brush coatings, which resemble a desert landscape. If you really need to focus on efficiency, talk to us. We spray – and not just with enthusiasm!
Water turbine coating – our technology is not only suitable for large impeller diameters. Here is a Francis impeller with a diameter of just under 600 mm (23 inches) from a small Austrian hydroelectric power plant. Someone who can coat something like this by spraying should be at the table when you plan the renovation of your hydroelectric power plant . . .
Francis impeller coating – can you coat it yourself? No, at some point, even with the greatest motivation, experience and special tools are irreplaceable. Still want to try it yourself? Then let's find a way together, but we must have one goal: maximum quality instead of the lowest price!
Francis runner coating - it is the details that determine the quality of a turbine coating. These include substrate preparation, processing temperature, adhesion and layer thickness on the blade edges, uniformity of application, execution of coating boundaries, and much more, which is what makes turbine protection so difficult!
Francis impeller lining - MetaLine is at home in hydropower. Here you can see it in a power plant in Costa Rica. Why do our customers value our advice even beyond national borders? Because we also say no when necessary! If the operating parameters of the plant are not compatible with our product, we withdraw. That is our promise!
Francis turbine protective coating – Accessibility to the turbine blades is the biggest challenge with Francis turbines. If possible, the impeller is mounted so that it can be rotated vertically for coating. For this reason, we never apply this special coating when the turbine is installed!
Turbine runner coating – MetaLine 785 achieves a wear resistance depending on the impacting angle in the range of AISI316 - but is 8 times lighter in weigth. That is the reason as to why hydro turbine manufacturers worldwide investigate more and more into the MetaLine softcoating philosophy...
Francis impeller coated with MetaLine 785 – coating is done in vertical direction with constant rotational movement
Francisturbine coating – Anything else available which is smoother? Anything else available which is more cavitation resistant? Anything else available which is as low in weight? NO!
Hydro turbine coating – there are 5 good reasons for a MetaLine elastomeric turbine coating: cavitation protection, surface smoothness, ultra-low weight, tension-free character, vibration resistance!
Francis medium sized impeller coated with MetaLine – the coating thickness amounts to approximately 2 mm
Turbinecoating – MetaLine Series 700 can be applied in a fluid-flow optimized smoothness and surface characteristic
Nozzle hood of a Pelton turbine coated with 4 mm MetaLine 785 – in two-colour version for optimum wear protection control
A coating with 4 mm MetaLine 785 helps the operator of this Portuguese Power Plant sleep better at night
Kaplan impeller in a French power plant at the river Rhein coated with MetaLine Series 500
Hub of a Francis turbine coated with 2.5 mm MetaLine 785 – perfect, yellow and permanent
Size is the decisive factor here – Kaplan turbine blades coated in our central workshop with MetaLine 785
Quite unusual and not due to the book – a Francis impeller coated partially with MetaLine 785 in place without removing it
Turbine frame constrution coated with MetaLine 590 in a pump storage power station in Luxembourg. Inspection was carried out after 5 years, nothing to complain about!
Turbinecoating – MetaLine 785 has been used in a thickness of 2,5 mm to protect this turbine frame construction to prevent wear and corrosion. The photo was taken during manufacturing, prior the outer piping was welded on after installation on site
Wicket gate coating – destructive impact should be answered with absorption forces. However most people try to repair theses damages with semi-hard epoxy-ceramic products! Do you know a ceramic which is really impact resistant? If not, follow our elastomeric technology MetaLine Series 700 – as most of the turbine manufacturers
Spiral housing of a Francis machine in the Swiss Alps – coated with 2.5 mm MetaLine 785 (the latest inspection reports are available)
Inlet of a water brake deep in the Tyrolean Alpes – coated with 4 mm MetaLine Series 500
Suction pipe coating – MetaLine 785 is used as a wear and corrosion protective coating inside this turbine suction pipe in the swiss alps
