Cable/Pipe Tolerant BlocksMade of zero halogen, intumescent elastomericpolymer. Each block accepts a range of cableand/or pipe diameters enabling the completerange of standard sizes to be covered by asmall number of blocks. Hawke´s uniqueinspectable colour coding shows that the tophalf and the bottom half are correctly matched forsizes

Blank Filler BlocksMade of the same material as the cable/pipeblocks, filler blocks also come in the samemodular size range. Blank filler blocks are usedto fill up unused space in the frame. The blocksare all marked with their modular size.

The Compression System1. End PackerThe final element of the frame installation, this isinserted above the compression plate and thebolts tightened to seal the whole frame.

2. Compression PlateThis goes on the top row of blocks, to distributethe pressure from the compression tool andcompression system.

StayplatesEach evenly packed row of blocks is held by astayplate to assist with assembly, before the nextrow is packed on top.

The Transit FrameMade of primed or plated mild steel, stainlesssteel or aluminium, a Hawke frame is carefullywelded at the corners and finished to the highestquality. Hawke frames can be cast within aconcrete wall, cemented into a wall, bolted to awall or welded or bolted to a metal bulkhead.

Open FramesAll frames are also available as open versions,for use where cables are already in position.

Hawke Round Transit Frames - HRTHawke round Frames effectively seal cables and pipes passingthrough circular apertures, and pressure seal against fire, water andgas, etc. The seal is formed by tightening the compression bolts whichexpand the system radially, this causes pressure to be exerted againstthe aperture wall and closes down the tolerant blocks

Hawke Marine Transit Frames - HMXHawke Marine Frames are normally welded intodecks and bulkheads in order to provide a secureanchorage for the services which pass through them.HMX frames are made from 60mm x 10mm bar.

This enables a wide range ofcable or pipe diameters to beaccommodated by a compactrange of tolerant block sizes.

Hawke tolerant blocks havefive sealing faces that aredisplaced by the sealingprocess. This results in atolerance of up to 4mm forcable diameters.

The Hawke colour coded blocksystem provides totalinspectability of the transitinstallation even after assemblyhas been completed.

On each of the two exposedblock faces minimum andmaximum diameters are clearlymarked. This indicates thespecific sealing range of theblock size.

SELECTION AND SPECIFICATION PROCEDURE

8

Selection and SpecificationThere are two main starting points in practice.A. Cables or pipes known, no frame.The ideal way, is when the numbers anddiameters of cable or pipe are known, inadvance of ordering the frame. The procedureshould then follow route A.B. Frame already installed.However, if a transit frame and cables orpipes are already installed, and sealingspecifications are to be determined later,follow route B.

No frame, cable or pipe requirements to beadvised in future.

If a frame only is required, and all cable/piperequirements are to be advised at a later datein the contract, install as large a frame as ispossible, and fill it with blank blocks.

Modular Cable/Pipe Tolerant BlocksIn the Block Selector Table below, the firstcolumn indicates the module size, secondand third columns indicate minimum andmaximum diameters of cable or pipe whichcan be accommodated by each block.

Blank Filler blocks are suffixed ‘0’e.g. 15/0 20/0 etc.

Code NumbersFor ordering purposes block code numbersare made up from the numbers in columns 1and 2 and are indicated in column 5. i.e. A40 module block capable of accommodatingcable/pipe from 28mm diameter up to 31mmdiameter is denoted 4028. A HF prefixdenotes zero Halogen blocks.

NOTE: Two insert blocks are required foreach cable or pipe.

Hawke Cable/Pipe Tolerant Blocks

Hawke’s unique inspectable colourcoded blocks ensure that the topand bottom half of each block hasbeen correctly matched for size.

Hawke cable/pipe tolerant blockshave been designed with a degreeof flexibility in order toaccommodate variances in cablediameters. Additionally this flexibilityenables each Hawke block size toaccept a range of cable or pipediameters.

Available in seven sizes from 3mm to100mm in diameter, Hawke blocksare marked with minimum andmaximum cable diameters e.g.block size 3018 is marked withsizes 18/21 to signify that it willaccept cable diameters from 18mmup to maximum of 21mm.

In practice this means that a smallnumber of blocks canaccommodate the full range ofstandard cable sizes. There is lessinventory to manage and theinstallation and inspectionprocedure is much faster andsimpler than competing systems.

HawkeTransit SystemComponents

Cable/Pipe Tolerant BlocksMade of zero halogen, intumescentelastomeric polymer. Hawketolerant blocks are produced in modularform to accommodate cables and/or pipesizes ranging from 3mm to 100mm indiameter.

1. The frame can be cast directly into a wallor floor.

4. Frames can be bolted to floors and wallsin either of the options shown. For boltedinstallations mastic should be insertedbetween the frames flange and the structure.Use Hawke mastic Ref. 966.When frames are reverse fixed then 9mmclearance is required to all faces.Hawke recommend a minimum of 1 hole percorner set 25mm in from outsideedge of frame with additional fixings at amax of 200mm centres.

5. Stayplates and compression plates haveretaining lugs. Clearance for these must beallowed when a frame is cast into a structure.This allowance is 12mm and shouldbe added to the total internal width of theframe to obtain the correct dimensions.Hawke Moulds have this allowance built in.(See Page 10).

2. The frame may be cast into a concretejacket this method being normally used forbrick and blockwork walls which in turn isfixed into the wall or floor.

3. Where transits are for cables of a largediameter, inclined installations of the frameis advisable to reduce the bending radius.

Size of fixing holes and type of fastener areto be established by the civil contractordependent on size of frame weight andstructure to which it is to be fixed.

Installations and Applications

There are several methods whichcan be used to install HawkeFrames, each methodgiving an inspectable professionalfinish to any cable penetration.When fixing frames toconcrete/brick type structures careshould be taken if usingexpanding type fixings as theycould burst into the aperture.For Hawke Frames which are castinto a wall or floor it isrecommended that a HawkePolystyrene Mould is used.Frames and moulds requiresupport to ensure that the correctposition is maintainedwhilst the concrete is beingpoured. This may be achieved bynailing through the shuttering intothe mould.Hawke Moulds are available tosuit sizes 2, 4, 6 and 8 frameswith 300mm lengths and may becut to suit the depth of the wall orfloor asrequired.

HawkeCivil Transit System

Mastic ApplicationEach 330ml tube of mastic should besufficient to mount and seal 3 individualframes or a multiple frame of up to 4 apertures1.Prior to application of sealant ensure thatfaces to be sealed are dry and free fromgrease and any loose material, ensure thattransit frame mates up with any fixings/holesalready present checking especially theaperture over which the frame is to bemounted.2.Cut nozzle on mastic to produce a beaddiameter of approximately 8mm.3.Apply two parallel rows of mastic and runa bead of mastic around each hole as shownin Fig.6.

4.The mastic can be applied to front or rearof the frame dependant on the installation,see Fig.7.5.The frame can now be placed over itsfixings and the fasteners tightened to clampthe frame to the wall. In tightening the fixturesthe mastic should be extruded out of thedecreasing gap between frame and structure,any excess should be removed and disposedof. When tightened up to the requiredamount, the mastic should be faced off to theframe leaving a fillet of mastic around theinternal and external edges of the frame.See Fig.7 above.

Lightweight sheet steel backing plates areavailable to be used in conjunction withHawke Civil Frames. These maintain theopenings through the walls and floorsand add to the finished appearance of theinstallation.

It should be noted that the backing plates donot add to the fire resistance of a transitassembly and should not be used to stop firespread in cavity walls.Backing plates are produced in standardlengths for wall thickness of 60mm to200mm for sizes 2, 4, 6 and 8 framesplus multiples thereof, but specials can bemade.Please state thickness of wall when ordering.

The aperture in the bulkhead/deck should be cut out such that the gap surrounding theframe 1mm.If gap is in excess of 1mm weld material may be added to the bulkhead/deck cut faceto reduce the gap. The bulkhead/deck should then be dressed and prepared aspreviously stated.

Prior to completing welds on either side of the bulkhead the frame should be tackedinto position as in the sketch above. The tack welds reducing the amount of distortionin the parent metals.The frame must be welded from both sides of the bulkhead.

Welding Sequence1st (A) underside, 2nd (B) underside,3rd (C) topside, 4th (D) topside

Note: Allow adequate time for cooling to prescribed levels to prevent cracking betweeneach weld run. Weld runs should not start or stop at a tack weld but should run overa tack.

1. Simply wrap the gauge tightly around thecable or pipe from the measurement line.2. Reading along the measurement line willreveal the correct block size for the cable orpipe and identify it by colour code.e.g. 4022 RED

Where there is an overlap between twoblock sizes e.g. 6052 or 9053, either sizecan be selected to best use the availablespace in the transit frame.

The following diagrams explain step by step how easy it is toinstall Hawke cable/pipe tolerant blocks into Civil or MarineTransit frames.

Draw up a Hawke DesignTemplate to determine your

cable/pipe layout.1 Make sure the frame is clean,

then pull cables or pipes through,placing the largest at the bottom.(Note: Use open ended frame to fit aroundexisting cables/pipes).

2 Lubricate the inside of theframe and all the insert blocks.3

Begin packing the frame.A stayplate is inserted

between each layer of insertblocks.

4 Insert the compression platebefore the last row of blocks

or earlier if required withadditional stayplates.

5 Pack the last row, insert thecompression tool and

tighten until there is sufficientroom to fit the tapered end packers.

6

Insert two outside packingpieces then remove tool before

fitting centre block.7 Tighten the nuts on the

endpacking to compress andcomplete the seal. Approximately10mm of thread should protrudeon each bolt.

8 Hawke’s unique colour codingsystem enables the installation

to be visually inspected aftercompletion and ensures correctmatching of the block halves.

1 Measure the inside of pipe oraperture to ensure that it is within

the tolerance of the Round TransitFrame to be used.

2 Insert the Round Transit Frame andopen the two front plate*. No

lubricant should be applied to theaperture or outside of the frame

3

Pull the cables or pipes throughthe frame. (Note: Use open ended

Round Transit to fit around existingcables/pipes).

4 Lubricate the inside of the frameand each of the insert blocks.5 Begin packing the transit frame

starting at the bottom andfinishing at the top. Ensure that theblocks are pushed firmly against therear retaining lip.

6

Slide the two front plates togetherand tighten the nuts 2mm

each time, applying equal pressure toboth plates*. The bolts should betightened until the cables/pipes aresealed. A minimum of 10mm of threadshould protrude on each bolt.

7 Hawke’s unique colour coding system enables the installationto be visually inspected aftercompletion and ensures the correctmatching of the block halves.

8 EXTRACTION OF SYSTEM Extraction is achieved by releasing thecompression, i.e. by reversing steps 5 and6 and screwing M8 bolts(not supplied) intothe threaded holes at each corner of thefront plates. This releases the assemblyfrom the aperture and allows the systemto be disassembled.

HRT Applications

The HRT is certified for use in civiland marine installations.

The HRT seals cables or pipeswithin cast pipes, welded tubes orcore drilled holes.

HawkeRound Transit System

1.Measure the outside diameter of each cable and ensure that the diameter iswithin the cable range marked on the front of the block that seals each cable.

2.Check that all colour codes on the block pairs are matching.

3.Check that there are sufficient blocks installed into the frame and that thereare no gaps not sealed by blocks.

4.If the transit application is in excess of 3.5 bar high pressure stayplatesshould be used ref. 931p, together with an extra 5mm sealing strip.

5.Check the correct amount of compression has been applied to the end packer bolts,10mm of thread on each bolt should be protruding.

Adhesive Copper Strip

Provided to build up to theinsertblocks and the strippedcable. The cable outersheath should be strippedto a maximum width of2cm to expose the cablescreen. All the cablesrequire the removal of theouter sheath toachieve contact betweenthe cable screen and theblocks. The copper EMIshielding tape withconductive adhesive iswrapped around thecable screen until thenominal outside diameterof the cable is achieved.This is important to ensurecomplete conductance ofthe electromagneticpulses/fields in the innerwalls of the steel frameagainst earth.

The Hazards of RFI/EMP

The need to protect sensitive electronicequipment against extraneouselectromagnetic and radio frequencyradiation is an increasing and criticalfactor in the design of equipment andinstallations.

A major concern is to ensure the integrityof operation of the equipment such ascomputers, signalling control andcommunication systems by effectivesealing and low resistance earthcontinuity bonding at cable and pipeentry points of a low ‘noise’ environment.Electromagnetic Compatibility (EMC).This is the term used to express theability of electronic equipment or systemsto operate satisfactorily in a givenenvironment without responding toelectrical noise or emitting unwantednoise.

The Hawke EMC Cable Transit System.Hawke’s system has been furtherdeveloped from the highly successfulCivil and Marine Transits which areequally suitable for cables or pipes.

Electromagnetic compatibility isachieved by reducing theElectromagnetic interference (EMI) to alevel which in most applications willnot disrupt the proper operation of theelectronics.

HawkeEMC Transit Systemfor Cables and Pipes

Testing ProceduresHunting Communication Technology Limited, Electromagnetic Assessment Group, werereferred to as specialists with extensive testing facilities. A series of three specified tests wererecommended to assess the transit performance and provide design data.

F O R C A B L E S A N D P I P E S

Fig 1.– Test for Shielding Effectiveness(No. U2501/TR/6660)The aim of the test was to measure theshielding effectiveness of the Transit by amethod generally in accordance with MILSTD 285. The testing was actually performedusing a swept measurement techniqueemploying a spectrum analyser with trackinggenerator to 1GHz and a Scalar networkanalyser from 1GHz to 10GHz.Conclusion:The Transit showed good shielding results being inexcess of 70dB over much of the tested frequencyrange.

Fig 2.–Test for Current Leakage(No. U2501/TR/6661)The test was designed to assess theconductivity of the Transit when used with avariety of cables. As there is not a standardspecification for this assessment, a test methodwas formulated which measured theconductivity in terms of current leakage fromthe cable shield to earth within a frequencyrange of 100KHz to 500MHz.Conclusion:Based upon the worst case data obtained, itwas observed that the current leakage wasbetter than 35dB over the frequency range100KHz to 500MHz. Infact, for most of thefrequency range the current leakage was atleast 50db.

Fig 3.– Test for transient (pulse) conductivity(No. 2501/TR/6662)The tests involved assessing the transientconductivity of the Transit when used with avariety of cables. The method used measuredthe conductivity in terms of current leakagefrom the cable shield to earth under thetransient conditions. The test was based uponDEF STAN 59-41 using transients consisting ofa 100KHz damped sinusoid applied by acurrent transformer.Conclusion:The current leakage under transient conditionsfor the cable set ups tested show a minimuminsertion loss of 30dB.
