Pipe Systems » P.E. Sleeves



Polyethylene Sleeving is a tubular film of low density polyethylene slipped over and snugly fitted to a pipe at the time of laying. It is used to supplement the basic pipe coating (metallic zinc + bituminous paint) in certain cases of highly corrosive soils, or in the presence of stray currents.

The polyethylene film is made of low density polyethylene (LDPE) in tubular film and is slipped over and snugly fitted to a pipe by means of:

  • adhesive plastic tape at each end.
  • intermediate tie fasteners

The technique using a barrel sleeve (applied outside the trench) and separate joint sleeve (applied in the trench after jointing) is preferable to the technique using a single sleeve (socket and barrel), since it provides better protection.


Protection Mechanism

Polyethylene sleeving supplements the zinc coating. Its protective mechanism consists of insulating the pipes from corrosive soil (suppression of electro-chemical cells) and from the ingress of stray currents.

Even if a small amount of water infiltrates the sleeving it still provides protection by substituting a homogeneous environment (ground water) to a heterogeneous environment (soil).


Standard: ISO 8180

Polyethylene sleeve 200 micron thickness (250 microns is available on request) is supplied in accordance with ISO 8180 and AWWA C-105.
