CONTENTS
Making the most of limited water supplies in rural locations is often difficult
because of the pressure loss problems we get with standard hose.
Local Authority Fire Chief
New regulations mean we need to make provision for additional water
supplies for use in fire fighting following an aircraft accident.
Airport Fire Chief
Having bought large capacity monitors to protect our open top floating
roof tanks we found that ordinary fire hose was insufficient to feed these
water hungry cannons.

Pressure Loss Reduction
When fluids are pumped down
any kind of pipe pressure energy
is lost through friction with the
pipe wall and via turbulence
caused by fittings and other
factors that may disrupt the flow.
Increasing the diameter of the
waterway can dramaticallyreduce this pressure loss a 1%
increase in diameter produces a
5% reduction in pressure loss.
Duraline Hi-Vol Systems bring the benefits of a larger diameter
waterway plus additional advantages.
Duraline Hi-Vol moves huge quantities of water very quickly over long
distances with minimal friction losses. A single length of 125 mm (5
inch) Duraline Hi-Vol can move the same amount of water as eight
lengths of 64 mm (2.5 inch) fire hose.
To assist in understanding the relationship between pressure, flow
and hose diameter in hose layout planning Angus has produced a
simple-to-use computer software package called HoseCalc to give
a theoretical solution to the fluid dynamics of large diameter hoses.
The theoretical results obtained using HoseCalc have been verified
in practical demonstrations witnessed by independent inspectors.
HoseCalc is available on floppy disc from Angus Fire or as a download
from the internet at :
http://www.angusfire.co.uk\htm\wnpres49.htm.
The following table of results from HoseCalc shows how pressurelosses can be dramatically reduced by using Duraline Hi-Vol.

WHAT ARE THE BENEFITS OF USING
DURALINE HI-VOL LARGE DIAMETER HOSE?
Uses fewer pumps in relay
than traditional fire hose.
Relay pumping ties up valuable
resources like pumping
appliances, fire-fighters, and
many lengths of standard
diameter fire hose. It is also
highly vulnerable to vehiclefailure. With its much simpler
logistics Duraline Hi-Vol releases
all these resources so they can
be better employed elsewhere
and also reduces the overall cost
of the fire fighting operation.
Eliminates the logistical nightmare of spaghetti on the fire
ground.
Many lengths of standard fire hose on the fire ground can pose a
serious safety hazard to fire crews. Replacing them with a few lengths
of Duraline Hi-Vol makes the fire ground much safer.
This was the experience of fire crews in Lancashire Fire & Rescue
Service when they used FETCH recently at this massive blaze at a
rubber factory.

Duraline Hi-Vol is the big brother
of the world famous Angus
Duraline fire hose. It features
specially formulated high grade
synthetic rubber extruded
through an all synthetic woven
jacket to give Duraline quality
performance.
Duraline Hi-Vol is designed for
long storage life and
maintenance-free service in
even the harshest
environments. This is essential
since it will spend more time in
storage than in use - it is no
good if you take it out and
it leaks.
If any kind of water supply hose kinks then it may be badly damagedwhen dragged. With heavier large diameter hose this is even more
important. Duraline Hi-Vol is tough and durable with exceptional
resistance to kinking.
Duraline Hi-Vol exceeds the requirements of the most demanding
international standard BS 6391 Type 3 for resistance to abrasion,
heat, chemicals, oil, weathering, ultra-violet light and ozone, including
100% pressure testing.
It is manufactured in compliance with BS EN ISO 9001:1994 quality
management systems. Raw materials, components, and finished
products are rigorously tested and inspected to ensure excellent
product reliability.
WHAT IS DURALINE HI-VOL AND WHAT MAKES IT
SO IDEAL FOR WATER TRANSFER?

HOW DO YOU TRANSPORT, DEPLOY
AND RETRIEVE DURALINE HI-VOL ON ROAD SURFACES?
The most common way of
transporting and deploying
Duraline Hi-Vol is in flaking
boxes. These can carry up to
around 2 km of Duraline Hi-Vol
and offer a low cost and simple
deployment technique. The hose
is simply drawn out of the boxes
and lowered on to the ground.
The Angus FETCHSystem (Fast
and Easy Techniques for
Collecting Hi-Vol) enables fire
crews to bring Duraline Hi-Vol
back into storage after an
incident with the minimum of
physical effort (a single coil of
5 inch Duraline Hi-Vol can weigh
50 kg). It avoids the risk of injuries
and fatigue during emergenciesand training exercises and so
complies with Manual Handling
Regulations.
FETCH comprises a simple but
cleverly designed twin-drum
friction system with very few
moving parts for maximum cost-
effectiveness and reliability in an
emergency. The mechanism is
driven by an independenthydraulic power pack. As an
option it can be PTO driven.

HOW DO YOU TRANSPORT, DEPLOY
AND RETRIEVE DURALINE HI-VOL ON ROAD SURFACES?
The Angus FETCH System is supplied as an
assembled skid enabling fire services to custom
engineer it into their own vehicle preferences
and budgets. This approach has proven
extremely popular.
Vehicle layouts may be sub-contracted to a third
party, built on a modified chassis by fire service
engineers or designed and built by a vehiclemanufacturer.

HOW DO YOU TRANSPORT, DEPLOY
AND RETRIEVE DURALINE HI-VOL OVER ROUGH TERRAIN?
FireKat
The Angus FireKat Series 3 is a large-diameter
hose deployment and retrieval system specially
designed for rough terrain. It is highly
manoeuvrable with excellent off-road handling
capabilities, making it ideal for applications
where speed of deployment is critical. Its key
design feature is simplicity - there is little that
can go wrong. And of course with this simplicitycomes affordability!
Fully self-contained four wheel drive all terrain vehicle
based on a Unimog type chassis carries 1 km of 5 inch
(125 mm) Duraline Hi-Vol with additional storage space
for fire fighting equipment.
Deploys one kilometre of Duraline Hi-Vol in only2-3 minutes depending on the terrain.
Hydraulic reeler collects the Duraline Hi-Vol - the only
manual effort required is to guide the hose from side to
side! The Duraline Hi-Vol is then unwound into the hosestorage area ready for action.
Duraline Hi-Vol takes the pressure from the pumper and puts
it at the business end where its really needed with negligiblepressure loss.

HOW DO YOU CONNECT LINES OF DURALINE HI-VOL TOGETHER?
In the past some fire services were reluctant to standardise on large-diameter hose because of concerns
about how best to connect the lines together. This is no longer the case because globally the Storz
coupling has become established as the standard coupling for large-diameter hose.
Angus Fire offers a comprehensive
range of lightweight field-replaceable
Corru-Grip Storz couplings for use
with Duraline Hi-Vol.
The Angus Jumbo Wye is designed
for those high water demand
situations where supply and/or
distribution requires multiple high
volume lines.
The Angus Five-Way Gated
Distribution Manifold or Phantom
Pumper is a multipurpose distribution
device available with special fittings
on request, and as with all Angus
Duraline Hi-Vol system components,
you can rely on the lowest possible
pressure loss across a broad rangeof flows.
The Angus 4-way in-line collecting
head. Available in other outlets andconfigurations.
Incoming Gated Relief Valve. Allows
full control of water pressure (9revolutions to open). Rotatable
offering varying discharge options.
Pressure relief operates with valve in
open or closed position.
The Duraline Hi-Vol Relief Elbow is
designed for use where gate valvesare not desired. Features include
directional discharge port, air bleed
and carrying handle.

Angus offers a range of customised reelers designed to individual
requirements. Hose deployment from a reeler system is considerably
slower than FETCH or FireKat. In addition, it is not possible to deploy
continuous lengths greater than 200m without the need to couple
up to the adjacent reel.
Consideration should also be given to the overall weight of the trailer
and whether it will conform to statutory towing regulations. Also the
correct towing vehicle needs to be established in relation to theweight of the fully laden trailer.
Finally, a decision needs to be made on powering the reeler. The
choice is to either use hydraulics from the prime mover or include a
hydraulic power pack on the reeler trailer.
Angus Fire offers a full range of hose ramps and techniques for
managing traffic logistics around incidents where Duraline Hi-Vol is
used.
The picture shows an all steel solution for 5 (125mm) hose although
ramps in other materials such as rubber and PVC are available.
