Two of Richmond‘s most recent pipe roller challenges have been to provide a turn-key solution for loading a new pipeline inside an existing larger diameter pipeline.
Posing a number of challenges relating to the loading process, load capacity required and lack of access for installation of roller assemblies, Richmond’s in-house design team implemented a design consisting of a band and rollers to drastically reduce friction ensuring a safe and economical process not only protecting both internal and external pipe but also acted as a pipe support once fitted.
A steel band fitted to the outside of the pipe with either two or three rollers welded to this frame, provides the basis for the pipe supports and rolling mechanism all in one. The pipe bands can be fitted by securely tensioning in place and reduce the need for welding onsite.
Depending on the environmental conditions, load capacity and rolling resistance or friction required, Richmond manufactures the rollers in engineered plastics such as nylon or polyurethane.
Richmond’s latest design has been used in Northcote, Victoria, as an alternative to a dry sliding design on the refurbishment of a water pipeline.
The scope of the project saw Richmond supply 50 pipe bands with a capacity of 900 kg – each fitted with two 110 mm nylon rollers. This particular project located a 1,127 mm pipe inside a 1,350 mm pipeline.
This particular Richmond design can be suited to various diameters, as the company prides itself on its ability to conceive and deliver high performance products for the pipeline industry.
