Type "N" sleeves

The "N" type sleeve is designed for pressureless sealing of penetrations. It protects the space between the support pipe and the casing or drill pipe from the ingress of contaminants (soil, sand, water).

 

  • Easy to install
  • suitable for thick-walled PE pipes
  • A very strong external fixing strip
  • has the ability to dampen vibrations
  • compensates for the thermal elongation of the pipe without unlocking the connection
  • High resistance to aging
  • Very flexible


Application


Intended use:

  • sealing, protection against the infiltration of liquids, solid elements such as soil, sand and other elements in the space between the conduit and the casing at the ends of the culverts to the extent described in the table


 Types of pipes:

  • All types of smooth-walled pipes, manufactured from any material and regardless of wall thickness, in the case of axial, non-axial, and angular arrangement of the conduit pipe within the casing pipe


Used in:

  • water, gas, wastewater, heating, industrial networks and other
