• Modular system to assemble insulator rings, which allows spacers to be used on a wide pipe diameter range therefore reducing inventory costs.
• Spacers are quickly and easily assembled by manually fitting elements one into the other.
• The tooth insertion method allows on site adjustments to fit a wide range of pipe diameters.
• Spacers are manufactured entirely out of high density polyethylene (HDPE). No metal bolts or attachments are required.
• A low friction coefficient guarantees an easy insertion into the casing.
• Designed and tested to maintain continuous and long term support for the carrier pipe and its contents.
• Spacers provide a constant projection around the entire circumference of the carrier pipe.
• Spacers provide long term protection from corrosion.
• Spacers can be installed on steel-coated pipes, concrete pipes, ductile iron pipes or plastic pipes.
• Heights 25 mm and 41 mm homologated according to SNAM Rete gas specifi cation (GASD a 09.01.06 and GASD C 09.06.00).
• Tightening by tool type C90 for height up to 90mm, tool type a200 for height from 110 a 120mm.
