Polypropylen isulators are universally applicable in the installation of pipelines when the carrier pipe runs inside a casing.

Plastic insulators provide various advantages:

easy installation of the carrier pipe since the plastic material reduces the friction coefficient to a minimum
minimised friction revents damage to the protective coating and insulation of the pipes
a wide range of skid heights ensures concentricity of the carrier pipe in the casing if required
excellent insulating properties of the plastic material ensures:
all requirement of cathodic protection are met.

Plastic insulators are suitable for all pipe diameters from 25 mm upwards and many skid heights are available to suit specific requirements.
