On the 2nd November 2021 the DENSO Group Germany revealed their new pipeline protection product.

The SEALID® All-in-1 Tape provides protection against corrosion as well as mechanical loads in a single step – without additional primer and without the use of other devices.

Fulfilling increasingly stringent requirements of ISO, EN and DIN standards, the new Tape adheres to 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.

Without the use of a primer an extremely tough tape with special adhesive properties is requiered. The new all-in-1 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. The tape is impermeable to water vapour, oxygen, soil bacteria and soil electrolytes. The protective hose achieves a minimised cathodic disbondment together with peel and lap shear strength.

DENSO describes their new product as "efficient and with a low-cost application at the construction site".

More benefits according to DENSO are:

  • In contrast to conventional tapes and tape system, there is no need for a primer or a second tape. SEALID® is just wrapped once.
  • It eliminates the need to preheat the steel surface as well as the tedious shrinking and air removal, as is the case for heat shrinkable sleeves. Errors are prevented from occurring in the first place.
  • In contrast to viscoelastic/petrolatum tapes, no additional products are needed for mechanical protection. This eliminates timely and costly work steps.
  • SEALID® can be applied independent of the weather conditions, as opposed to liquid coatings. Protective equipment and associated devices are not necessary, because no harmful substances are used.
