4 Strength4.1 Vulcathene Mechanical and Enfusion pipes,couplings and fittings will have adequate resistanceto the forms of loading associated with installation.

4.2 The products should be protected from impacts, forexample, from heavy vehicles such as fork-lift trucks usedon commercial premises.

5 Performance of joints5.1 The joints will not be adversely affected by thermalmovement when correctly made.

5.2 The joints will remain watertight under conditions ofpipeline movement in excess of those expected to occurin normal good drainage practice.

6 Flow characteristics6.1 A drainage system comprising VulcatheneMechanical and Enfusion pipes, couplings andfittings will have satisfactory flow characteristics.

Non-swept branch connections are restricted inaccordance with BS EN 12056-2 : 2000.

6.2 Offsets in the wet portion of a discharge stackshould be avoided. However, if the S-bend offsets are tobe fitted in this position, large radius bends should beused BS EN 12056-2 : 2000. A ventilation stack maybe necessary above and below the offset (see Figure 3).

Figure 3 Offsets in discharge stacks

7 Resistance to chemicals7.1 The Vulcathene system is resistant to a wide rangeof noxious chemicals for laboratory applications. Thesuitability of the system for a particular application canbe determined using CP 312-1 : 1973 and/orISO TR 10358 : 1993.

7.2 The products will be unaffected by those types andquantities of chemicals likely to be found in the effluentsdefined on the Front Sheet of this Certificate.

8 Resistance to elevated temperatures8.1 The products have adequate resistance to thetemperatures likely to occur in the effluents defined insection 3.1.

8.2 Where temperatures above 20°C are expected,Thermal Stress Relief Units (SRUs) should be installed.The SRUs should be installed in accordance with themanufacturer’s recommendations. Vertical SRUs shouldbe installed at every floor level where a stack connectionexists; where no stack connection exists one SRU everytwo floors is sufficient.

9 MaintenanceSections of the system can be removed easily andreplaced. Access must be provided in accordance withBS EN 12056-2 : 2000.

10 DurabilityWhen used within the conditions andrecommendations given in this Detail Sheet theproducts will have a serviceable life equivalent to

conventional domestic plastics drainage systems.Prolonged exposure to strong oxidising agents in alaboratory application may reduce the serviceable life ofthe system.

Installation

11 GeneralInstallation should be in accordance withBS EN 12056-2 : 2000 and the manufacturer’sTechnical Guide.

12 Procedure12.1 To make a joint, the pipe is cut to the requiredlength using a cutter designed for plastic pipe. The pipeends should be square and smooth. A handsaw andmitre block can be used as an alternative, but careshould be taken to ensure that cut pipe ends are squareand free from burrs.

Mechanical joints12.2 To cut a groove in the pipe, the Vulcathene W26series cutting tool is used, one tool for each size of pipe.The full depth of cut is achieved in two stages obtainedby adjusting the cutting tool for ‘half depth’ and then ‘fulldepth’, using the control provided. The blade isretracted before withdrawing the tool from the pipe. Thegroove is checked to ensure the absence of swarf.

12.3 To assemble the joint, the W23 series nut isplaced on the pipe followed by an olive. The olive ispushed over the pipe until it seats into the groove.Before making the joint to a fitting, the olive and fittingshould be checked to ensure they are clean and freefrom dirt. The thread of the fitting is smeared withpetroleum jelly, pushed over the olive and the nuttightened by hand.

12.4 For the other pipe to be jointed, the proceduredescribed in sections 12.2 and 12.3 is repeated.

R is as large as possible (200 mm min)d = D/2 or for ventilated systems as required in(Table 6 of BS 5572 : 1978) if larger than D/2

D 75 mm (see note 2 below)

Note 1 No branch connections in dotted area unless vented.Note 2 Arrangement (b) is only possible if D is 75 mm or larger.Note 3 No offset venting is required in lightly loaded systems of

up to three storeys in height.Note 4 Offsets above highest branch connections do not require

venting.

12.5 The W23 series nuts are tightened using theVulcathene W36 series spanners.

12.6 It is important that the nuts are tightened as theinstallation progresses and not left until the job iscomplete.

Enfusion joints12.7 A pipe scraper is used to scrape the end of thepipe equivalent to the depth of the socket plus 50%.Removal of the slick or ‘skin’ on the surface of the pipe isimperative in order to obtain a good fusion joint. Onceprepared, this area must not be handled or allowed toget dirty.

12.8 The pipe is inserted all the way to the stop at thebottom of the socket.

12.9 It should be decided whether the joint is to bewelded singly or in series. See Table 2 if multiple jointsare to be made which indicates the maximum number ofjoints relative to the pipe size.

12.10 The appropriate-sized clamp(s) should beloosely fitted over the hub(s) of the socket(s) to be joinedand positioned flush with the socket opening.

12.11 The clamp(s) should be tightened round thehub(s) of the socket(s). It is important that the clamp(s)is/are fully tightened to obtain a homogeneous joint.

12.12 Before using the Enfusion Control Unit all cablesmust be unwound from the protective frame.

12.13 When Enfusion Control Unit is turned on it willself test and should display a copyright message.

12.14 Instruction on the display to ‘connect outputlead’ should be followed. If fusing a single joint, theoutput leads should be connected to one joint or ifmultiple joints, the link leads should be utilised asrequired.

12.15 Instructions are then displayed to ‘select pipesize’. When the correct size is displayed the start buttonis pressed and the Enfusion Control Unit displays thetemperature and the welding time.

12.16 When completed, the Enfusion Control Unitemits an audible alarm and displays the message‘disconnect output lead’. During this period the EnfusionControl Unit counts down to zero.

12.17 The joints should be allowed to cool(30 seconds), before gently disconnecting the leadsfrom the joints.

12.18 The joint should be left undisturbed for at leastfive minutes before the clamp(s) are removed.

Making multiple Enfusion joints12.19 Table 2 indicates the number of joints whichcan be fused at any one time utilising additional linkcables in series, as shown in Figure 4. The chart onlyapplies to joints of the same size. The use of the multiplejointing method for connecting joints of differing sizesshould not be attempted.

Design Data

3 General3.1 Where the Vulcathene system is to beused in a laboratory application withchemical effluents not suitable for discharge

into a public sewer, the building drainage shouldrun to a holding tank. The local Water Authorityshould be consulted regarding details of theeffluents likely to be discharged into the laboratorydrainage system.

3.2 Vulcathene mechanical sinks, troughs, dripcups and traps are satisfactory for use in domestic,commercial and public buildings in accordancewith BS EN 12056-2 : 2000 for the conveyanceof domestic drainage and sewage as is permittedto be discharged into public sewers by the PublicHealth Act 1936 (England and Wales), and sewageas is permitted and defined by the Sewerage(Scotland) Act 1968 and the Water and SewerageServices (Northern Ireland) Order 1973.

4 Strength4.1 Vulcathene mechanical sinks, troughs,drip cups and traps will have adequateresistance to the forms of loading associated

with installation.

4.2 The products should be protected fromimpacts, for example, from heavy vehicles such asfork-lift trucks used on commercial premises.

5 Performance of jointsThe joints will not be adversely affected bythermal movement when correctly made.

6 Effectiveness of trap seals6.1 The Vulcathene traps have a depth ofseal of 76 mm. The seal will withstand theapplication of an air pressure of 70 mm

water gauge and will not therefore nullify the effectof the water seal in the trap.

6.2 In the opinion of the BBA, the Vulcathene anti-siphon bottle traps types W561 and W571comply with the requirements of Department ofHealth and the Welsh Office, Health TechnicalMemorandum Building Components Sanitaryassemblies 64.

7 Flow characteristics7.1 The flow characteristics of the sinks,troughs, drip cups and traps minimise the riskof blockages.

7.2 At flow rates of up to 10 litres per minute theVulcathene dilution recovery traps are effective incollecting and retaining solid matter.

8 Resistance to chemicals8.1 The Vulcathene system is resistant to awide range of noxious chemicals forlaboratory applications. The suitability of the

system for a particular application can bedetermined using CP 312-1 : 1973 and/orISO/TR 10358 : 1993.

8.2 The products will be unaffected by those typesand quantities of chemicals likely to be found in theeffluents defined in section 3.1.

9 Resistance to elevated temperaturesThe products have adequate resistance tothe temperatures likely to occur in theeffluents defined in section 3.1.

10 Health and hygieneIn clinical laboratory applications the use oftraditional plug/overflow assemblies with a sink ortrough is considered to be unhygienic. In suchinstances a standing waste tube should be used.

11 Maintenance11.1 The W561 and W571 anti-siphonbottle traps and the W681 dilution recoverytraps have sumps that can be removed for

cleaning by unscrewing. The chamber of thedilution recovery trap type W691 is removed byunscrewing the flange assembly. The dilutionrecovery traps Types W612 and 910G are cleanedby removing the dip tubes and carefully flushing theinterior of the dilution chambers. Access is providedin accordance with BS EN 12056-2 : 2000.

11.2 The use of abrasive agents should be avoidedwhen the sinks, troughs and drip-cups are cleaned.

12 DurabilityWhen used within the conditions andrecommendations given in this Detail Sheetthe products will have a serviceable life

equivalent to conventional plastics drainagesystems. Prolonged exposure to strong oxidisingagents in a laboratory application may reduce theserviceable life of the system.

Installation

13 GeneralInstallation should be in accordance withBS EN 12056-2 : 2000 and the manufacturer’sTechnical Guide.

14 Procedure14.1 Typical laboratory bench waste runs areshown in Figures 3 and 4. The sinks, troughs anddrip cups are jointed to the traps by a 1½" BSPloose nut coupling. Typical sink and drip cupinstallation details are shown in Figure 5.


Figure 5 Typical sink and drip cup installation details

14.2 The Vulcathene 604 series sinks and 605series troughs have a self-adhesive sealing striprecessed in the sink flange which forms an effectiveseal between the sink and the underside of thelaboratory bench.

14.3 The traps with borosilicate glass basesshould be supported from beneath to avoid weightstrain on other pipework connections.
