DEPROTEC®-DRM PP 609 & 809

Non-woven material made from polypropylene fibres (809) and mixed PP/PET fibres (609) to provide additional mechanical protection for corrosion prevention encasements on steel and cast iron pipelines, plastic pipes and district heating systems.

  • High mechanical resistance.
  • Easy application.
  • Resistant to rotting even in aggressive soils.
  • Water and current permeable.
  • Heat resistant.

DEPROTEC®-DRM PP 609 & 809 are robust non-woven materials made from PP (809) and PP/PET fibres (609) designed to provide additional mechanical protection for field joint and factory coatings. With a weight per unit area of 900 g/m², the product offers high resistance to mechanical and thermal stresses and is exceptionally easy to apply. The product boasts good permeability for soil electrolytes, allowing it to be used on cathodic protected pipelines.

DEPROTEC®-DRM PP 609 & 809: Industries and solutions

DEPROTEC® rockshields and hoses are a high-quality and cost-effective alternative to traditional sand back-filling, if large-grained excavation material is being reused or if pipelines run through rocky areas. Across the world, DEPROTEC® rockshields and hoses reliably and permanently protect more than 1 million square metres of corrosion prevention technology on pipelines and in power station and pipeline station construction applications against mechanical damage — helping to guarantee safe and economic operation.
