Hydro-Service chain acts like caterpillar tracks
A
Renold Chain product story
Edited by the Engineeringtalk editorial team
Jun 23, 2009
National Power Rodding is using Renold's Hydro-Service chain as caterpillar tracks on underground pipe-crawlers to inspect the integrity of sewers and water-waste pipes.
The crawlers carry miniature cameras and lights so that the interior of pipes and sewers can be filmed to locate problem areas, without the need for excavation.
Renold's Hydro-Service chain has been fitted with attachments to which National Power Rodding's engineers have secured rubber pads that drive the crawlers like the caterpillar tracks on a tank.
Hydro-Service was chosen because of its anticorrosion properties.
Each component of the chain is mechanically treated prior to assembly, ensuring secure and consistent protection from corrosion.
Renold claims its Hydro-Service chain resists corrosion for 30 times longer than ordinary carbon-steel chains.
