Lanes Group business UKDN Waterflow (LG) has made an investment in ultra-violet pipe lining technology to meet the growing demand for the rehabilitation of large diameter pipes, culverts and sewers.

The lining division of UKDN has purchased a dual core curing system specifically designed for lining pipes with a diameter between 600mm and 1200mm. The division is using it to rehabilitate large diameter culverts for Network Rail.

The company states that there are only two ultra violet dual core systems in the UK that can be used on mobile UV lining equipment. The majority of pipe rehabilitation contractors hire them on a project by project basis.

Head of Rail Maintenance for UKDN Waterflow (LG), Eamonn Maloney, commented: “Having the system in-house will allow us to plan culvert and sewer rehabilitation programmes more effectively, making them easier to implement, and more cost-effective for rail infrastructure customers.

“Our ability to invest in this technology is an example of the benefits that have flowed from Lanes Group’s acquisition of the business 12 months ago. Indeed, the dual-core system will be made available to all Lanes Group sewer rehabilitation customers.”

UKDN has also come up with a mobile UV lining pod that will operate the dual core light train, which can be lifted onto or off of trollies or all terrain trailers for transport.

There are four lamps on each core of the ProKASRO dual core UV light system. Once a maximum diameter has been set for the guide arms, a safety system will prevent the arms from over elevating beyond the chosen diameter.

UKDN lining manager Jack Talbott said: “We can remotely adjust the arms up or down to guide the light source through changing diameters, or sections of deformed pipes during the curing process.

“The operator keeps the light source as close as possible to the liner all times. This allows the quickest curing time, which can be essential when lining rail pipes during short track possessions.”
