World-first by DENSO for Reliable Corrosion Protection
Reliable and permanent protection of pipe sections and weld seams are one of the main challenges in pipeline construction. A wide range of often time-consuming processes that differ for each application have previously been used. SEALID® All-in-1 Tape is the DENSO Group Germany’s patented innovation for universal application.
For the first time it provides unprecedented protection against corrosion as well as mechanical loads in a single step – without additional primer and without the use of other devices. By fulfilling ISO and EN standards, SEALID® All-in-1 satisfies the increasingly stringent demands in pipeline construction. A single wrap is enough to comply with ISO 21809-3 at operating temperatures of up to +70°C. The requirements of EN 12068 and DIN 30672 for class C50 are also met with a single wrap.
The new all-in-one solution is manufactured in a genuine multi-layer co-extrusion process. When wrapped in a spiral pattern the tape forms a completely closed protective hose with exceptional durability. Impermeable to water vapour, oxygen, soil bacteria and soil electrolytes, the protective hose achieves a minimised cathodic disbandment together with an outstanding peel and lap shear strength.
