3. Durapipe UK has over
60 years experience
in plastic pipework
systems
Part of the
Aliaxis group
Over 15,000
employees
Operate in 85
different countries
Globally recognised
brands such as:
4. The first PVC pipes
introduced
Vulcathene chemical
drainage system
The first plastic valve was
produced in Europe by FIP
The first ABS pressurised
drinking water pipes
90% of new domestic properties use
plastic hot and cold plumbing systems
C-PVC hot and cold
plumbing system

5. No limescale build-up
No bore restriction,
flow rate maintained
Pump energy efficiencies
Reduced bacteria build-up
6. Plastics have a smoother surface than
traditional metals
Plastics’ surface smoothness remains
constant; metals’ surface smoothness
deteriorates
Surface smoothness can be expressed as
‘Friction Loss’ represented by K values
(Plastics = 0.01 & New Carbon steel = 0.1)
*source : Wilo Select Software
Lower pump duty/energy savings
7. Most plastic pipe systems
offer a 50-year design life
Third party approvals
Rigorous testing
8. Many plastics have high
impact resistance
ABS, PE & PP are ductile
at low temperatures
9. Less than 1/6
weight of metal
Easier manual
handling
Simpler
installation
Reduced
transportation
carbon emissions
NO heavy
lifting
equipment
Improved
health & safety
10. Metal prices fluctuate
Most plastic prices are
more stable
More accurate
cost projection
11. General Rule
ABS
PVC-U
C-PVC
Polypropylene
Plastic pipework systems are suitable for
a variety of chemical applications
Plastic systems have varied chemical
resistance properties
It is important to select the correct
plastic for your application
In general terms, Polypropylene is
more resistant than ABS
HIGHLOW
When selecting pipework,
it is important to consider:
Conveyed ChemicalsChemical Concentration TemperaturePressure
PVDF
General Rule of Chemical Resistance
12. Independent bodies
Universally recognised
Rigorous and stringent testing
Reliability and assurance
Product confidence
Water Approvals
Manufacturing
Standards
Marine
Approvals
REG 31
13. Technical support including product
training and installation demonstration
Material estimate advice and
expansion guidance
Chemical suitability
CAD software and BIM packages
Technical information from Luckins,
Hevacomp, AutoDesk Revitt etc.
14.
15. Thermal movement can be
easily calculated
Expansion and contraction
can be accommodated
Numerous methods of
compensating for thermal
movement
All pipework systems expand
and contract
16. Dual contained pipework
systems are designed
to protect the environment
they operate within.
Driven by
specification
Offering visual
or electronic
leak detection
Ensuring
valuable fluid
recovery
Preventing
hazardous
leaks into the
environment
Protecting
workforce and
machinery
17. Valves are integral to any industrial
pipework system
Selecting the valve/pipework together:
– Guarantees a fully matched system
Dependent on the requirements of the
application
IT IS IMPORTANT TO CONSIDER:
Temperature
Chemical Concentration
Pressure
System Control
19. Allowing the user to operate a process or
series of actions remotely
Removing the need for manual operation
An effective solution for managing a network
of valves or complicated processes
Electric (100 – 240vAC) (24vAC/DC)
On/Off
Positioning
Battery Back Up

Two main types
of actuation…
20. The accuracy of flow control
and measurement is crucial
It is important to consider the
type of flow control required
Understanding application and
conveyed media is critical to
system selection
Paddlewheel & electromagnetic
flow control options
Paddlewheel:
Clean Fluids
Magmeter:
abrasive fluids
(sediment)
21. Plastics are lighter
and easier to transport,
reducing fuel costs
and carbon emissions
Scrap during
manufacturing
can be recovered
Smooth bore pipes
means less friction
loss, lower pumping
energy required
Plastics use
less energy than
metals in
manufacture
Plastics can be
recycled
at end of life
22. Conforms to highest
standards
Smoother surface than
traditional metals
50 Year design life
Lifetime pump
efficiencies
Reduced maintenance
& system repair costs
due to no limescale/
corrosion build-up
23. Standard and Approvals
