Universal solution for major
pipeline installation
The versatility and unique qualities
of ductile iron pipe from Saint-
Gobain PAM UK have earned it a
key role in a major water pipeline
installation in northeast England.
The replacement of the 16km
Tyneside North Circular Main
between Horsley and Gosforth was
a major project for Northumbrian
Water, undertaken by Carillion.
While much of the work was fairly
straightforward and used standard
900mm Saint-Gobain ductile iron
water pipe, four sections – notably
those underneath major roads such
as the A1 and A696 – required
a different approach. For these
sections, tunnelling underneath
the road would have meant major
delay and disruption to traffic, and
so a solution based on trenchless
technology was needed.
Saint-Gobain PAM UK’s PAM
Universal pipe features a boltless
restraint solution, and can be simply
pushed together to create a secure seal with strong pipe to pipe anchorage. The
product can withstand high pulling forces with up to 1.5° deflection, as well as
pressures of up to 25 bar – well above the legal requirement for this type of
product.
The new pipeline also passed through the grounds of Newcastle Airport, and
to avoid disruption here an oversized tunnel was created, through which the
Saint-Gobain pipes were pulled on ‘spiders’ by a mobile excavator to facilitate
rapid installation.

Super Padder for
large-diameter
pipeline jobs
CRC-Evans Pipeline Equipment has
launched its most advanced, highest
volume padding machine. Built to handle
pipeline diameters of 36" and greater,
the Super Padder has been engineered
to increase productivity, efficiency and
safety on the job. Screening huge piles
of dirt for ditch padding requires heavy-
duty equipment combined with ease
of operation. The Super Padder is self-
loading and self-propelled, allowing
operation with less equipment and
manpower. A single operator controls
the machine by a wireless remote that
manages speed, direction and all other
functions from a safe distance with
maximum visibility.
Designed by Laurini, the Super Padder
is ultra-stable and can work uphill or
downhill. The machine is track-mounted
to handle the largest jobs in the toughest
terrains, with a high-frequency vibrating
screen that outputs large volumes of
fines from either side and from varying
distances. Screened rocks and debris
are discharged outside of the track path,
either into the ditch or away from it.
CRC-Evans Pipeline Equipment builds
a complete line of pipeline construction
equipment, including pipe bending
machines, ditch padding equipment,
pipe handling and support equipment,
pipe facing and bevelling machines,
internal line-up clamps, and laybarge
and coating plant equipment. The
company is a subsidiary of CRC-Evans
Pipeline International, a provider of
specialised equipment and services for
the construction of pipelines.
