ATE gets a new pipeline
Boksburg-based Alfred Teves Brake Systems (ATE) got a new
pipeline without having to dig through the trenches.
By Rescue Rod
THE PROBLEM
A 40-year-old main pipeline water supply at ATE
was losing approximately 30 000 litres of water
per day due to pinhole corrosion leaks in the
host pipe. Rescue Rod’s Primus Line was used
to rehabilitate the pipeline without obstructing
traffic at the busy factory. the system is suitable for different media, as well as
various pressures to suit specific jobs. The Primus Line
technology has numerous benefits, including small
construction pits, short rehabilitation times, and a low
level of impact on the environment. The installation is
possible in the most confined spaces and with minimal
machine deployment.
The pipeline ran from the main factory gate under
the truck weighbridge for 44m, turning right at a
45-degree angle for 15m and then left at a 30-degree
angle towards the factory for 16m. The traditional
open trench method was not suitable for this project,
as it would have resulted in water cuts indefinitely —
with the added expense of a new pipeline excavation
and installation times. Added to the surface-kn own
challenges when exposed, the water pipeline was very
close to stormwater pipelines, which added to space
restrictions and confirmed that the best solution was
lining with Primus Line as opposed to traditional open
trenching pipe replacement. Using the Primus Line combines the flexibility and extreme
lightness of the textile sheath with the strength of steel
tubing. These properties are obtained by using seamless-
woven Kevlar fabric and a dual-component plastic coating
applied to the sheath, which is proofed against fluid egress
on the inside and abrasion on the outside.
THE SOLUTION
Primus Line is different from other systems in the
sense that the liner can be used in a pipeline with
bends — allowing for quick insertion times and fast re-
commissioning. The system consists of a flexible
Kevlar-reinforced liner and specially developed end fittings.
Primus Line is self-supporting and is not bonded to
the host pipe. Developed by experienced engineers,

ADVANTAGES OF TRENCHLESS TECHNOLOGY
Primus Line incorporates various aspects of trenchless
technology. According to the Southern African Society for
Trenchless Technology (SASTT), trenchless technology
refers to technology for the servicing, rehabilitation, and
replacement of existing, as well as the construction of
new public utilities and other services underground,
without digging any trenches.
Trenchless technology has the following benefits:
• Trenchless pipe repair methods are environmentally
and economically superior to open construction.
• Trenchless pipe lining helps restore hydraulic
pressure and fixes underground pipes without
disrupting road, rail, and shipping traffic.
