Europe has stripped 500 tons of lining
from 43km of pipe as part of a mammoth
conversion project for a manufacturer of
construction products.
The custom-designed, semi-automated
unit was used on a total of 8,000 pipes,
which measured 5.5m in length and ranged
in diameter from 100 to 700mm, in an
operation that took 950 hours to complete.
The solution produced by Jetstream
Europe was not only compact and speedy,
but also proved to be cost-effective
and productive.
The manufacturer needed to convert a
huge batch of stocked pipes from one type
of seal coat system to another. Previously,
the manufacturer had burned out the lining in
a stove and scrubbed the bore back to bare
metal before relining the pipe. However, this
was a major time-consuming and expensive
method as it also destroyed the expensive
outer coating, which had to be shot-blasted
away and re-applied, explained Danny
Monaghan, Jetstream Europe’s technical
and operations manager. “The pipe maker’s
engineering team had used a water jetting
process before, but this was only on a few
pipes, and not on the scale that this project
required.”
Pipe samples were sent to Jetstream
Europe’s facility, where trials were carried
out to ensure the equipment could
thoroughly remove the lining at the rate
demanded. As well as providing the water
blast system, Jetstream Europe trained and
certified eight staff members to the Water
Jetting Association’s Safety Awareness

Jetstream Europe’s pipe lining removal project
standard, so that they could operate and
maintain the kit.
“The customer was not only very
impressed by the results, but also by the
quality and reliability of Jetstream Europe’s
equipment,” said Mr Monaghan. “What’s
more, only a few parts required replacing
during the entire water jetting operation.”
