Non-woven material (2000 g/m² weight per unit area) made from polypropylene fibres to provide additional mechanical protection for corrosion prevention encasements on steel and cast iron pipelines, plastic pipes and plastic jacket pipes in district heating systems.

  • High mechanical resistance.
  • Easy application.
  • Resistant to rotting even in aggressive soils.
  • Water and current permeable.
  • Heat resistant.
  • DEPROTEC®-DRM PP 200 Plus is a polypropylene non-woven material designed to provide additional mechanical protection for corrosion prevention coatings. With a weight per unit area of 2000 g/m², this product is as thick as and provides mechanical resistance equivalent to DEPROTEC® rockshields. The product boasts good permeability for soil electrolytes, allowing it to be used on cathodic protected pipelines.
  • DEPROTEC®-DRM PP 800 Plus Plus meets the requirements of Gaz de France for class TR.

DEPROTEC®-DRM PP 2000 Plus : 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.
