Power stations, refinery
& station construction
Powerful in every detail
The world's highest safety standards are applied in the construction and operation of power plants and refineries because of their enormous impact on people, the environment and their considerable technical complexity. These requirements apply to all plants, pipelines and tank farms. Their durable corrosion protection, reliable insulation and permanent sealing ensure occupational and operational safety to prevent accidents and incidents.
Pipelines that are under load or situated in areas of high humidity have wet surfaces. Previously, it was only possible to repair these kinds of pipelines by taking them out of service — which was always a costly exercise. With VivaxCoat®, these kinds of pipes can be repaired reliably during operation.
Pipelines and fittings that are used to transport hot media or are situated in warm environments can be protected reliably with DENSO®-Cal, which boasts a design temperature of +120°C or +248°F.
For decades, our DENSOLEN®-PE/butyl tapes have been successfully applied in the construction of power stations at design temperatures of -50°C to +85°C or -58°F to +185°F. Individual product systems can be combined to offer resistance to UV rays, bacteria or electrolytes.
The DENSO®-TB System is a highly effective corrosion protection and at the same time a permanent seal for the transition area between steel and concrete in above-ground tank bottoms. With storage tanks, there is a risk of water and air penetrating into the gaps between the lower steel plate and the concrete base. You simply apply the solvent-free product without drying or preheating, as it is even suitable for damp surfaces. Even with tank movements and temperature changes, the system remains flexible and adaptable.
Above-ground pipes and applications need full protection against water vapour and oxygen, combined with maximum UV protection. Our DENSIT®-AL/-PB sealing tapes are not only ideal for insulation, but also reflect sunlight off their metallic surface, reducing the surface temperature of the encasement material.
Station construction: Two challenges – one solution
There are two key challenges affecting soil to air interface areas: Firstly, atmospheric corrosion is different to corrosion that takes place under the ground. Secondly, the interface areas are subject to high mechanical loads and various movements during construction.
DENSOLID®-IPL insulation plates provide excellent electrical insulation and form a reliable electrical separation between cathodic protected pipelines and foundations made from concrete. This insulation prevents voltage drops. DENSOLASTIC®-SU reliably protects the foundations and fixtures of gate valves, which are subject to mechanical and corrosive loads.
The sprayable and liquid coating DENSOLID®-FK2 has been applied successfully for decades to provide reliable protection in soil to air interface areas.
Protecting fittings and flanges from corrosion is of particular importance due to the complexity of these pipeline components. DENSO®-PF Mastic and DENSO®-Plast offer an easy-to-apply solution that provides long-term, reliable protection.
For decades, our DENSOLEN®-PE/butyl tapes have been successfully used to create seals, provide electrical insulation and prevent corrosion in station construction applications, at design temperatures of -50°C to +85°C, or -58°F to +185°F.
In stations, sleeve pipes on fitting assemblies are often not adequately protected. Our DENSO®-KS compound reliably prevents corrosion while ensuring that the assembly retains its mobility, even at temperatures as low as -10°C or -23°F.
