‘Largest’ inflatable
pipeline stopper
for temporary jobs
The pipeline stoppers division of Huntingdon
Fusion Techniques Limited, UK, has claimed
to have manufactured the largest inflatable
pipeline stopper, measuring 2,000mm in
diameter. It is designed for the overnight
and temporary stopping of large diameter
pipelines.

As pipelines are being laid, it is essential
to close them off overnight to prevent
the entry of animals and human beings,
and also to prevent the ingress of dirt or
potentially contaminating liquid or solid
materials. Mechanical stoppers are often
used for smaller pipelines. However,
as pipeline diameter increases, the
availability and transportation of such
large mechanical stoppers becomes
restrictive, so lightweight, low cost, off-the-
shelf inflatable stoppers become a viable
alternative.
Pipestoppers™ inflatable stoppers are
available from 2" to 84" (50 to 2,000mm)
as standard, but can be made to special
dimensions and shapes, and with special
materials.
Similar stoppers are available in
rectangular shapes, with heat resistant
materials and for catching hydrocarbon
fluids and metal debris in vertical cutting
operations. The stoppers are delivered
with a suitable length of inflation hose and
a leak tight shut off valve.

Scotchman Industries, Inc, USA,
manufactures the CPO 315 RFA roller feed,
fully automatic cold saw. This saw provides
high quality and uninterrupted cutting on
tubing, solids, and extrusions.
The machine is suitable for high volume
and long length applications that require
very accurate and clean cuts. The
CPO 315 RFA is equipped with either
a supply table or a full bundle loading
attachment. Either system allows the saw
to automatically load, trim, cut and sort
lengths up to 120" (60" is standard), and
Portable x-ray warning system
Shaw Inspection Systems, UK, a developer of digital non-destructive testing systems,
has launched a portable x-ray warning system for use with temporary radiation barriers.
The new x-ray warning system consists of a central marshalling unit and tripod-mounted
warning units. The system is IP64 rated and suitable for both indoor and outdoor use.
Each warning unit features an audible siren and three 60W rotating mirror beacons:
green for x-ray ready, amber for x-ray imminent and red for x-ray on. The siren sounds
at up to 110dB at a distance one metre and can be adjusted by means of an internal
volume control.
The system’s marshalling unit can drive up to three chains of warning lamps, with up
to eight warning lamps per chain. With 60 metre cables between warning lamps each
branch can extend up to 480 metres. The marshalling unit is designed to connect to an
existing x-ray warning circuit, but can also be used to connect with other emergency
stop and warning circuits.
Each system can be supplied with a full set of accessories, including heavy duty tripods,
interconnection cables, terminating loop back plugs and wooden crates for storage and
transportation.
The portable x-ray warning system meets all the requirements of the UK Ionising
Radiation Regulations 1999 (IRR99). It is based on the same electronics as used for
Shaw Inspection Systems’ high quality x-ray warning lamps.
For customers upgrading existing facilities or for installation into new radiation
enclosures, the tri-state warning units are available as a separate product. Each unit
includes a bulb failure circuit and indicator, which is activated if any of the bulbs fail. It
also includes four additional safety circuits which can be configured to be opened or
closed in the event of a bulb failure.
