Coating and rehabilitation

Solutions for maximum safety

Steel pipes are coated with a corrosion prevention system, either at the factory or on the construction site. Alongside a simple application process, factors such as a long service life and, in particular, reliable protection against corrosion and mechanical loads are key.

The rehabilitation of coatings on complete pipelines or sections of pipeline takes place while the pipe is in operation, so the pipe does not have to be taken out of service, which is an exercise that can prove costly. Due to the risk of explosion, only cold-processed corrosion prevention systems can be used in these applications. To put the pipeline back into full operation quickly, the process for applying the product must be rapid and simple.


Coating at the factory or on the construction site

As a spray coating that is reliable and quick to apply, the solvent-free solution DENSOLID®-FK2 can be applied in the factory or on the construction site during restoration work or in new installations. The product's exceptional hardness combined with just the right amount of stretch provide optimum resistance to mechanical and corrosive loads at operating temperatures up to +80°C (+176°F). 

DENSOLEN<sup>®</sup>-AS40 Plus

Rehabilitation – Millions of metres of success

Operational pipelines can be protected against corrosion and mechanical impact quickly and permanently using cold-processed DENSOLEN®-PE/Butyl tapes. The layers of the tape fuse together, due to  the 3-ply structure, to create a protective hose that is fully sealed. Immediately after application, the pipeline can be operated at full load. Many millions of metres of DENSOLEN®-PE/butyl tapes successfully protect pipelines across the world. 


Almost a century of reliable corrosion prevention

Our cold-processed DENSO® tapes have been protecting pipelines against corrosion for almost a century, particularly pipelines under load and with a condensate film forming on the surface. In 1927, with the invention of passive corrosion prevention for pipelines in the form of petrolatum tape, DENSO set an industry quality standard that is still recognised today.
