PVC Pipes are
Clearly Improved
Visual control over the fluid flow process is now easier to achieve
thanks to an expanded range of clear PVC-U piping products.
As a result, system designers have a greater diversity of
options to incorporate clear pipes and fittings into their
systems. Transparent piping has a number of different uses,
including visual sight glasses or where complete clear systems
are assembled, providing inspection throughout the entire
process.
Metric sized clear PVC-u pipes are now available from stock in
sizes from 6mm to 250mm, with a standard length of 5m.
There is a choice of pressure ratings in most sizes ranging
from 4 to 25 bar. All of the sizes are available with a thin wall
option making them suitable for other, non-piping
applications, such as display products.
Manufactured by GEHR in Germany, and stocked in plain
ended lengths, pipes are individually packaged to ensure that
they arrive in pristine condition at the work place.

Also added to the product range is a new series of schedule
80 clear PVC-u pipes from Harvel Plastics of the USA. This is
a heavier wall pipe available in a range of diameters from 1/4”
to 4”. The schedule 80 system allows for higher working
pressures and therefore opens up the opportunity to use this
product for more demanding or critical process applications.
Despite the increased wall thickness, clarity is not
compromised, thus ensuring that for higher working pressure
applications complete visual control of the process is still
available.
Clear PVC-u piping is joined together using standard cold
solvent welding methods and is fully interchangeable with
standard PVC piping components. It is increasingly being used
for double containment piping applications, where a visual
indication of the integrity of the internal piping systems is
required. For critical applications requiring higher margins of
safety and integrity, HARVEL FlameTech 25/50 low flame and
smoke translucent piping can also be supplied.

Flow Monitoring for a Wide Range of Applications
Complimenting the popular ASV Stübbe variable area flow meters, a novel range of paddle wheel flow-sensors and flow transmitters are also available to
control or monitor flow.
A paddle wheel flow-sensor is installed so that when liquid flows through the pipe the paddle wheel rotates at the speed of the flow. The four bladed
rotor is manufactured from PVDF with a permanently embedded magnet in each blade. The sensor has a Hall effect transducer
in the body creating an output pulse that is processed by the integrated electronics into a square wave output frequency.
Paddle-wheel sensors are able to measure flow in both directions, and are equipped with ceramic rotor shafts with two
ceramic bearings, ensuring an extended life even at high velocities. Output signals are capable of transmission up to 50
metres without the need for additional amplification.
A range of installation fittings is available in PVC-u, Polypropylene and PVDF, with a variety of union end connection
configurations allowing for easy installation into the piping system.
The flow transmitter itself has an IP65 enclosure, which reads directly from the rotating paddle wheel to display flow rate and
volume. Using the on-board menu, further customisation is possible to show for example different
engineering units or measuring ranges.
This type of flow meter is unique because the paddlewheel is produced as an integral part of the installation fitting.
The sensor attaches to the installation fitting using a simple bayonet connection - however
because the sensor is completely isolated from the fluid it is possible to have a number
of paddlewheels located in a variety of positions, and to move the sensor from one to
another thereby reading multiple flow data with only one display.
Full details on this cost effective flow monitoring system are available on request.
Clic Pipe Clamps and Fixings A Complete System
Clic pipe clamps are designed for fixing a wide range of piping materials and cables, and the special “clic” fixing method makes
installation simple.
The patented design uses a ratchet principle to automatically lock the pipe or cable in place. After fixing the clamp in the required
position, the installer simply pushes the pipe into the clamp. A reassuring “clic” is heard as the clamp locks onto the pipe and
securely holds it in place. The fixing is permanent, although the ratchet lock can easily be undone with a screwdriver or any flat tool
if relocation is required.
Because the clic clamp uses a ratchet to lock, each size will also hold a range of diameters. For stockists and users of plastic
pressure pipe systems, this has a unique benefit - one clamp will hold both the imperial
and the equivalent metric pipes, thus eliminating the need to hold a stock of each size.
Safe for use within a temperature range of -40˚C to +80˚C, the material is unaffected
by weather conditions and ageing, as well as petrol/diesel and lubricating oils.
Polyamide is also an environmentally friendly material and it can be fully recycled.

PVC & CPVC Hot Tap Saddles
allow Live Connections to
Pipes Under Pressure
Occasionally a system shut-down may not be possible when
modifications are required. Isolating valves may be inoperative, or
there may simply be no opportunity to close off the fluid flow.
The new Hot-Tap Saddles from Spears allow for branches to
be installed in a live pipe run without the need to turn off the
pressure in the main pipe. The saddles clamp around an
existing pipe without any initial disturbance to the existing
line. Branch connections are then fitted, and the additional
pipework is fully made up. When this is complete and
pressure tested, a cutting tool contained in the saddle is
turned so that it cuts through the main pipe wall. As it is
withdrawn, fluid is allowed to enter the new branch piping and
the modification is then complete.
The Spears Hot-Tap Saddle is manufactured from PVC or
CPVC material and is specifically designed for industrial
applications.
Suitable for use on inch sized piping systems in the size range
2” to 6” diameter, the Hot-Tap saddles feature a 90˚ branch
outlet that can be used as either a spigot or a socket
connection. Outlet sizes are 3/ 4” socket with a 1” spigot, or
11/2” socket with a 2” spigot, a
combination which permits a variety of
possible transition connections.
Pressure rated to 16 bar at 20˚C, the HotTap saddle includes a built in cutter to cut a
hole in PVC or CPVC pipe. The special design
captures and retains the cut-out disc from
the hole, preventing it entering the fluid
stream.
Spears Hot-Tap saddles are
available with EPDM or Viton
O-ring seals, and choices of
zinc plated or type 316
stainless steel hardware. To
compliment this new range,
an extensive selection of repair
couplings, compression couplings
and expansion joints are also available.
Installing fittings with close centrelines is easier with the Spears
street elbows and tees.
Manifolds and other assemblies that are designed to be
assembled on tight centrelines traditionally use short pieces of
pipes to connect between the fittings, limiting the minimum
distance and requiring two solvent cement joints to be made.
The Spears street fittings use a combination of spigot and socket
ends to simplify the assembly procedure and to minimise the
required space. The street elbow, for example, is available in
both 45˚ and 90˚ angles. One end has a solvent socket, the other
a solvent spigot. A street tee has solvent sockets on the branch
and on one of the run connections. The other run connection is a
solvent spigot, allowing it to be directly connected to another tee
without the interconnecting pipe.
Spears street fittings are manufactured in both PVC and CPVC,
in sizes from 1/2” to 2”. Each connection is marked with stepped
angles to assist with positioning during assembly.

How Clic
works
Clic pipe clamps are available in a choice of 21 sizes, covering diameters ranging from
8mm to 127mm. Manufactured from dark or light grey nylon (Polyamide PA12), they are
equally suited to plumbing, heating and air conditioning as they are to the corrosive
environments typically found in the chemical industry or in swimming pools.

Clic, however, is not simply a range of pipe and cable clamps. It is a complete
“system” of pipe fixings, including multiple base plate mountings, spacers to offset
clamps in thicknesses from 2.5mm to 65mm, and a variety of adaptors to fix the
clamps to walls and metal plates, or to threaded rods in sizes from M6 to M12.
Users who are familiar with more traditional metallic fixing systems will find many of
their features incorporated into the Clic system. For example, by inserting a small
threaded flange into the clamp, or (in the larger sizes) by using the pre-tapped base, it
is easily possible to fix Clic clamps to threaded studding either as drop hangers or from
walls and floors.
Fix clamp to structure
The versatility of the system provides unlimited opportunities to install pipes or cables in
the most complicated situations, and it offers flexibility to combine the use of clic
fixings with other pipe support or channel framing systems.

Harvel has also developed Clear PVC
piping for use in semi-conductor,
sight-glass and double containment
applications. Most recently, Harvel
LXT has been introduced - a lowextractable piping system for ultra
pure water systems, offering
unparalleled levels of performance in
a PVC piping system.
Harvel Plastics has always been a leader in refining and perfecting extruded
plastics. Today they are recognised as a world authority on PVC and CPVC
piping products, with two production plants in the U.S.A. and distributors
world-wide.
The company was founded 45 years ago by Harvey Wismer, operating then
from a small rented basement. Their business survived the cramped space and
the regular flooding that occurred whenever the nearby river overflowed with
mud and water.
In 1966, a new 28,000 square feet facility was built at Easton, Pennsylvania,
on the site of their present
headquarters. This site has
continued to grow throughout the
years and the building now
occupies over one quarter of a
million square feet, with all
manufacturing and warehousing under one roof. A new plant,
warehouse and distribution centre now also operates from Bakersfield,
California, serving western U.S.A. and the Pacific Rim countries.
Harvel manage the entire production
process under one roof. They use
only the best compounds and blend
them in their own plant to achieve
consistent physical characteristics.
The single and twin screw extruders
have a wide-ranging capability and can produce pipe in diameters from 3mm to 750mm (30 inches), as well
as solid rods and other engineering shapes.
Lab testing is carried out on both the raw material and the finished product. Standard checks include
hydrostatic, squeeze and impact tests. Harvel’s own
criteria often considerably exceed industry standards.
Most importantly, throughout the company Harvel
demonstrate a clear and unconditional commitment to
customer service. Their technical support is second to
none in the industry, and is matched by their ability to
complete orders accurately and on time. Throughout the
years, Harvel has built a reputation as an innovator
backed by exceptional service, earning the name
“The Quality Line”.
The Wismer family are still at the head of the Harvel Plastics
business, complimented by a management team and over 120
employees.
Harvel Plastics helped to develop and produce the world’s first CPVC
pipe back in the 1960’s, and they have continued to innovate ever
since. Harvel were one of the first to develop BlazeMaster® speciality
plastics for fire sprinkler systems. Their pipe for this application has
set the standard for the product, which is required to pass arduous
fire exposure tests as part of the listing and approval process.

Quality Counts
IPS has successfully demonstrated compliance with the new ISO 9001/2000
standard, passing the latest audit with flying colours.
We were first accredited to the “old” BS 5750 quality standard in February
1993. Since then we have been re-audited several times by SGS Yarsley, and
our certification to the new standard was achieved during February 2002.
The two main themes of the new standard are customer focus and continual
improvement - two issues that have always been at the heart of the IPS
business activities.
Continuing the quality theme, IPS has also recently committed to achieving
the ISO 14001 standard by implementing an environmental management
system. Following an initial review of our systems and operations we have
introduced an environmental policy and have prepared a draft environmental manual.
Government targets and objectives will continue to raise environmental awareness, and IPS are committed to improving our
performance by controlling the impact of our products and services on the environment.
Technical Focus:
Using Cutting and Bevelling Tools
One of the critical areas in good welding practice for solvent cemented joints is the preparation of the pipe ends. This seemingly minor job
can have a major influence on the final joint integrity.
A good quality solvent cement joint is achieved by following a number of simple steps which when
combined should ensure that a leak free joint is consistently produced.
The first step is to cut the pipe ends. The squareness of the cut is critical to the joint strength. A
significant amount of the final joint strength is held in the very bottom of the socket where there is
the most “interference” to the fit. Cutting the pipe square allows the pipe to fully “bottom” in the
fitting, thereby having a major effect on the end result.
The use of a saw with a mitre box or, preferably, a rotary pipe cutter with a cutting blade that is
suitable for plastic piping is recommended. A range of pipe cutters is specially designed for plastic
piping, capable of handling diameters up to 800mm. In addition, many require minimal clearance
around the pipe, making them ideally suited for use in hard to access locations.
Copies of the IPS Quality Policy and the IPS Environmental Policy are available on request.
Plastic Pumps
Plastic bodied pumps provide an ideal solution to the problems
associated with the delivery of corrosive liquids - combining
superb chemical resistance with reliable engineering.
The ASV Stübbe range is manufactured using the latest
thermoplastic materials - Polypropylene, Polyethylene and
PVDF - providing resistance to a wide range of chemical
fluids including acids, bases and solvents.
In use since the 1970’s, the range includes one of the
largest selections of thermoplastic pumps, with capacities
from 0.12 to 600 cubic metres per hour at power
requirements between 120 watt and 110 kilowatt.
There are many different types and configurations to match
numerous applications,
including centrifugal pumps,
peripheral pumps, eccentric
pumps, diaphragm pumps and
vertical sump pumps. Options
include dry-running
capabilities and special seal
arrangements. The range is
completed by a wide selection
of accessories such as sensors
and switches for pressure and
temperature control.
Compact Welding
Equipment Improves
In-Situ Jointing
Making butt welded joints in hard to access locations is often a difficult
challenge - even for the most skilful operator.
Piping installations often follow routes in close proximity to walls,
floors or ceiling to allow for the simplified placement of pipe clips
and supports. In many installations, pipe runs also are adjacent to
cables, conduits and other services, limiting the access to a piping
system.
When repair or modification to this type of installation is required,
access is always high on the list of potential obstacles that need to
be overcome.
Weighing less than 5kg, and suitable for pipe sizes 20mm to
110mm, a new, highly portable welding unit is ideally suited to butt
fusion jointing in these hard to access locations. The MINIPLAST
butt welding system from WIDOS has a manually controlled planing
tool that is used to prepare the pipe ends for butt welding, and the
clamping units are also adjustable in 15 degree increments to allow
for the production of fabricated mitre bends.
The next step is to remove the internal and external burrs that are created when pipe cutting tools
are used. This is important for two reasons. Firstly, if the external burr is not correctly removed, it
can make it difficult for the pipe to “bottom” properly in the fitting. Secondly, an external burr can
scrape the solvent cement out of the joint and give
rise to “puddling” of excess cement at the centre of
the fitting.
To assist in the preparation process, simple pipe beburring tools are available to remove both internal
and external burrs. In addition, a wide range of hand
operated external pipe bevelling tools will produce a
smooth external chamfer ideally suited to solvent
cement jointing. The tools will work on
pipes in sizes up to 12” diameter, and
produce reliable, repeatable results on
each joint.
A useful pocket size guide to
producing solvent cemented joints is
available upon request from IPS. To
obtain your free copy, please
contact our sales office.
The MINIPLAST will make high quality butt welded joints in hard to
access PVDF, Polyethylene or Polypropylene piping systems. It is also
ideally suited to the
installation of
simultaneously welded
double containment
piping systems such
as AGRUSAFE or ASAHI
PolyFlo.
Further details of our welding equipment range, available for sale or to
hire, can found in the latest edition of the IPS Handbook. Copies are
available free of charge from our sales team.
