M a n i f o l d sMade Easy!Installing fittings with close centrelines is easier with the Spearsstreet elbows and tees.

Manifolds and other assemblies that are designed to beassembled on tight centrelines traditionally use short pieces ofpipes to connect between the fittings, limiting the minimumdistance and requiring two solvent cement joints to be made.

The Spears street fittings use a combination of spigot and socketends to simplify the assembly procedure and to minimise therequired space. The street elbow, for example, is available inboth 45˚ and 90˚ angles. One end has a solvent socket, the othera solvent spigot. A street tee has solvent sockets on the branchand on one of the run connections. The other run connection is asolvent spigot, allowing it to be directly connected to another teewithout 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 steppedangles to assist with positioning during assembly.

Clic Pipe Clamps and Fixings -A Complete System

2 3

Clic pipe clamps are designed for fixing a wide range of piping materials and cables, and the special “clic” fixing method makesinstallation simple.

The patented design uses a ratchet principle to automatically lock the pipe or cable in place. After fixing the clamp in the requiredposition, the installer simply pushes the pipe into the clamp. A reassuring “clic” is heard as the clamp locks onto the pipe andsecurely holds it in place. The fixing is permanent, although the ratchet lock can easily be undone with a screwdriver or any flat toolif 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 plasticpressure pipe systems, this has a unique benefit - one clamp will hold both the imperialand the equivalent metric pipes, thus eliminating the need to hold a stock of each size.

Clic pipe clamps are available in a choice of 21 sizes, covering diameters ranging from8mm to 127mm. Manufactured from dark or light grey nylon (Polyamide PA12), they areequally suited to plumbing, heating and air conditioning as they are to the corrosiveenvironments typically found in the chemical industry or in swimming pools.

Safe for use within a temperature range of -40˚C to +80˚C, the material is unaffectedby 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.

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 offsetclamps in thicknesses from 2.5mm to 65mm, and a variety of adaptors to fix theclamps 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 oftheir features incorporated into the Clic system. For example, by inserting a smallthreaded flange into the clamp, or (in the larger sizes) by using the pre-tapped base, itis easily possible to fix Clic clamps to threaded studding either as drop hangers or fromwalls and floors.

The versatility of the system provides unlimited opportunities to install pipes or cables inthe most complicated situations, and it offers flexibility to combine the use of clicfixings with other pipe support or channel framing systems.

Complimenting the popular ASV Stübbe variable area flow meters, a novel range of paddle wheel flow-sensors and flow transmitters are also available tocontrol 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 bladedrotor is manufactured from PVDF with a permanently embedded magnet in each blade. The sensor has a Hall effect transducerin 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 twoceramic bearings, ensuring an extended life even at high velocities. Output signals are capable of transmission up to 50metres 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 connectionconfigurations 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 andvolume. 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 - howeverbecause the sensor is completely isolated from the fluid it is possible to have a numberof paddlewheels located in a variety of positions, and to move the sensor from one toanother thereby reading multiple flow data with only one display.

Full details on this cost effective flow monitoring system are available on request.

Flow Monitoring for a Wide Range of Applications

PVC & CPVC Hot Tap Saddlesallow Live Connections toPipes Under Pre s s u reOccasionally a system shut-down may not be possible whenmodifications are required. Isolating valves may be inoperative, orthere may simply be no opportunity to close off the fluid flow.

The new Hot-Tap Saddles from Spears allow for branches tobe installed in a live pipe run without the need to turn off thepressure in the main pipe. The saddles clamp around anexisting pipe without any initial disturbance to the existingline. Branch connections are then fitted, and the additionalpipework is fully made up. When this is complete andpressure tested, a cutting tool contained in the saddle isturned so that it cuts through the main pipe wall. As it iswithdrawn, fluid is allowed to enter the new branch piping andthe modification is then complete.

The Spears Hot-Tap Saddle is manufactured from PVC orCPVC material and is specifically designed for industrialapplications.

Suitable for use on inch sized piping systems in the size range2” to 6” diameter, the Hot-Tap saddles feature a 90˚ branchoutlet that can be used as either a spigot or a socketconnection. Outlet sizes are 3/4” socket with a 1” spigot, or11/2” socket with a 2” spigot, acombination which permits a variety ofpossible transition connections.

Pressure rated to 16 bar at 20˚C, the Hot-Tap saddle includes a built in cutter to cut ahole in PVC or CPVC pipe. The special designcaptures and retains the cut-out disc fromthe hole, preventing it entering the fluidstream.

Spears Hot-Tap saddles areavailable with EPDM or Viton O-ring seals, and choices ofzinc plated or type 316stainless steel hardware. Tocompliment this new range,an extensive selection of repaircouplings, compression couplingsand expansion joints are also available.

Harvel Plastics has always been a leader in refining and perfecting extrudedplastics. Today they are recognised as a world authority on PVC and CPVCpiping products, with two production plants in the U.S.A. and distributorsworld-wide.

The company was founded 45 years ago by Harvey Wismer, operating thenfrom a small rented basement. Their business survived the cramped space andthe regular flooding that occurred whenever the nearby river overflowed withmud and water.

In 1966, a new 28,000 square feet facility was built at Easton, Pennsylvania,on the site of their presentheadquarters. This site hascontinued to grow throughout theyears and the building nowoccupies over one quarter of amillion 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.

The Wismer family are still at the head of the Harvel Plasticsbusiness, complimented by a management team and over 120employees.

Harvel Plastics helped to develop and produce the world’s first CPVCpipe back in the 1960’s, and they have continued to innovate eversince. Harvel were one of the first to develop BlazeMaster® specialityplastics for fire sprinkler systems. Their pipe for this application hasset the standard for the product, which is required to pass arduousfire exposure tests as part of the listing and approval process.

Harvel has also developed Clear PVCpiping for use in semi-conductor,sight-glass and double containmentapplications. Most recently, HarvelLXT has been introduced - a low-extractable piping system for ultrapure water systems, offeringunparalleled levels of performance ina PVC piping system.

Harvel manage the entire productionprocess under one roof. They useonly the best compounds and blendthem in their own plant to achieveconsistent 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 wellas solid rods and other engineering shapes.

Lab testing is carried out on both the raw material and the finished product. Standard checks includehydrostatic, squeeze and impact tests. Harvel’s owncriteria often considerably exceed industry standards.

Most importantly, throughout the company Harveldemonstrate a clear and unconditional commitment tocustomer service. Their technical support is second tonone in the industry, and is matched by their ability tocomplete orders accurately and on time. Throughout theyears, Harvel has built a reputation as an innovatorbacked by exceptional service, earning the name “The Quality Line”.

Quality Counts Technical Focus:Using Cutting and Bevelling To o l sOne of the critical areas in good welding practice for solvent cemented joints is the preparation of the pipe ends. This seemingly minor jobcan 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 whencombined 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. Asignificant amount of the final joint strength is held in the very bottom of the socket where there isthe most “interference” to the fit. Cutting the pipe square allows the pipe to fully “bottom” in thefitting, 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 issuitable for plastic piping is recommended. A range of pipe cutters is specially designed for plasticpiping, capable of handling diameters up to 800mm. In addition, many require minimal clearancearound the pipe, making them ideally suited for use in hard to access locations.

The next step is to remove the internal and external burrs that are created when pipe cutting toolsare used. This is important for two reasons. Firstly, if the external burr is not correctly removed, itcan make it difficult for the pipe to “bottom” properly in the fitting. Secondly, an external burr canscrape the solvent cement out of the joint and giverise to “puddling” of excess cement at the centre ofthe fitting.

To assist in the preparation process, simple pipe be-burring tools are available to remove both internaland external burrs. In addition, a wide range of handoperated external pipe bevelling tools will produce asmooth external chamfer ideally suited to solvent

cement jointing. The tools will work onpipes in sizes up to 12” diameter, andproduce reliable, repeatable results oneach joint.

Making butt welded joints in hard to access locations is often a difficultchallenge - 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 clipsand supports. In many installations, pipe runs also are adjacent tocables, conduits and other services, limiting the access to a pipingsystem.

When repair or modification to this type of installation is required,access is always high on the list of potential obstacles that need tobe overcome.

Weighing less than 5kg, and suitable for pipe sizes 20mm to110mm, a new, highly portable welding unit is ideally suited to buttfusion jointing in these hard to access locations. The MINIPLASTbutt welding system from WIDOS has a manually controlled planingtool that is used to prepare the pipe ends for butt welding, and theclamping units are also adjustable in 15 degree increments to allowfor the production of fabricated mitre bends.

The MINIPLAST will make high quality butt welded joints in hard toaccess PVDF, Polyethylene or Polypropylene piping systems. It is alsoideally suited to theinstallation of

simultaneously weldeddouble containmentpiping systems such as AGRUSAFE or ASAHIPolyFlo.

Further details of our welding equipment range, available for sale or tohire, can found in the latest edition of the IPS Handbook. Copies areavailable free of charge from our sales team.

IPS has successfully demonstrated compliance with the new ISO 9001/2000standard, passing the latest audit with flying colours.

We were first accredited to the “old” BS 5750 quality standard in February1993. Since then we have been re-audited several times by SGS Yarsley, andour certification to the new standard was achieved during February 2002.

The two main themes of the new standard are customer focus and continualimprovement - two issues that have always been at the heart of the IPSbusiness activities.

Continuing the quality theme, IPS has also recently committed to achievingthe ISO 14001 standard by implementing an environmental managementsystem. Following an initial review of our systems and operations we haveintroduced 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 ourperformance by controlling the impact of our products and services on the environment.

Copies of the IPS Quality Policy and the IPS Environmental Policy are available on request.
