Corrosion protection tapes: lamination versus coextrusion - Which production technology wins-out in the long-term?
Steel pipelines are capital-intensive, so their service life is critical. DENSO Group Germany impressively demonstrates the vital role that superior production technology plays in the operating life of a pipeline with the exceptionally long life of its three-ply corrosion protection tapes: even after 40 years in the field, the coating with a coextruded tape system still far exceeds the current corrosion protection requirements.
But why do some tapes protect the pipe better than others over long periods? What influence does the production technology have on the material properties and how does this change the quality of cor rosion protection tapes? The following comparison of the lamination and coextrusion manufact uring procedures provides the answers.
