ADVANTAGES1LABOR SAVINGS5 NONCONDUCTIVECompared to yesterday’s metal products, PVCreduces labor on typical installations by as muchas two-thirds, because it is easy to work with.PVC does not require the labor intensive toolsusually associated with steel products, such asvises, threading equipment and reamers.PVC eliminates the most dangerous second pointof contact in phase to ground faults. The use of aseparate grounding conductor gives a completeand positive ground for the entire system.6 CHEMICAL RESISTANTKraloy PVC ﬁttings are resistant to a wide rangeof chemicals such as acids, alkalis or saltsolutions. For more information on chemicalresistance, contact Kraloy customer service.2 EASY JOININGAll that is required to join your Kraloy ﬁttings withPVC conduit is Kraloy Solvent Cement (seesolvent cementing instructions, page 5).73 STRENGTHAGING CHARACTERISTICSAfter years of exposure to direct sunlight, heat,and extreme weather, Kraloy PVC ﬁttings retaintheir original properties. They are also resistant tofungi, bacterial action, rodents and termites,providing for a long and trouble free life.Kraloy PVC ﬁttings offer both high impact andhigh tensile strength.4 CORROSION RESISTANTPVC is resistant to external corrosion and pittingand will not rust. This ensures a lowermaintenance cost and a longer performance life.8 FIRE RESISTANCEAs a building material PVC offers outstanding ﬁreperformance characteristics. PVC will not burnunless an external ﬂame source is applied, andwill not sustain ignition once the ﬂame source isremoved. PVC has a ﬂash ignition temperature of850 F.3
SUPPORTDue to PVC’s light weight, support spacing is different than that used with metalconduits. Supporting straps should NOT be ﬁrmly tightened, to allow for linearmovement. The maximum allowable support spacing, per the National Electrical CodeArticle 352.30 (B) is as follows:SUPPORT SPACINGNominal Conduit DiameterNational Electrical Code Max. Support 4252-1/26363-1/27475768MAX OPERATING TEMPERATUREThe National Electrical Code (NEC) allows the use of rigid nonmetallic conduit(RNC) and ﬁttings in locations where ambient temperatures are not in excessof 122ºF.CUTTINGKraloy Rigid PVC Conduit can be easily cut on the jobsite by using ahacksaw, carpenter’s saw or PVC conduit cutters. For larger sizes of conduit,the use of a mitre box is also recommended to ensure a square cut.4
SOLVENT CEMENTINGAfter cutting PVC rigid conduit, sharp edges or burrs from inside the conduitshould be removed with a knife. Thoroughly clean the end of the pipe and insidethe ﬁtting with a pipe cleaner. In extreme weather conditions, a primer should beused to prepare the joint for solvent cementing. Apply a generous amount ofsolvent cement to both surfaces, slide together and give a quarter turn to ensuresolvent is spread evenly on the material. Hold together for a few seconds untilthe joint is made.Usually the solvent-cemented joint will be strong enough to install immediately,but in low temperatures and high humidity, extra time may be required beforemoving the pipe to install it permanently. Solvent cemented joints appear to “setup” instantly, but will take 24 hours to cure properly. After this time, the solventcemented joint has completely cured and is waterproof. Kraloy cement isavailable in half-pint, pint, quarts and one-gallon containers.HANDLINGSolvent cements should be used as received in original containers. Addingthinners to change viscosity is not recommended. If cement is jelly-like and notfree-ﬂowing, it should not be used. Containers should be kept tightly coveredwhen not in use.STORAGE CONDITIONSSolvent cements should be stored at temperatures between 40 F and 110 Faway from heat or open ﬂame. Cements should be used before the expiry date stamped on the container. If new cementis subjected to freezing temperatures, it may become extremely thick. This cement can be placed in a warm area where itwill soon return to its original, usable condition. However, if the product is gelled or hardened due to actual solvent loss(when a container is left open too long during use or not sealed properly after use), the cement will not return to itsoriginal condition. Cement in this condition has lost its formulation and should be discarded in an environmentally friendlymanner.SAFETY PRECAUTIONSSolvent cements are extremely ﬂammable and should not be used or stored near heat or open ﬂame. In conﬁned orpartially enclosed areas, a ventilating device should be used to remove vapors and minimize inhalation. Containersshould be kept tightly closed when not in use, and covered as much as possible when in use. Avoid frequent contact withthe skin. In case of eye contact, ﬂush repeatedly with water. Keep out of the reach of children.COLD WEATHERAlthough normal installation temperatures are between 40 F to 110 F, high strength joints have been made attemperatures as low as -15 F. However, the installer must ensure he has adequately softened the joining surfaces with aprimer. In addition, cement must be kept warm to prevent excessive thickening and gelation in cold weather.5

Due to the many variables in the ﬁeld, these ﬁgures should beused as a general guide only.After initial set, the joints will withstand the stresses of a normal installation. (A misaligned installation will cause excessivestresses in the joint). For long runs of pipe, care should be taken not to disturb joints for 1/2 to 1 1/2 hours before handlingor burying.AVERAGE NUMBER OF JOINTS PER PINT OR QUART OF CEMENTNominal Pipe SizeInches# of Jointsper Pint# of Jointsper QuartNominal Pipe SizeInches# of Jointsper Pint# of Jointsper PVC is a thermoplastic material that, when heated, becomes soft and pliable.As a result, its shape can be altered.A ﬂameless heat source is recommended to heat the pipe. AN OPEN FLAMESHOULD NOT BE USED. An electric unit or an infra-red propane unit isrecommended for heating the pipe.The necessary temperature for bending Scepter Rigid PVC pipe is 260 F.The pipe must be heated evenly over an area approximately ten times thediameter of the pipe before any attempt at bending is made. Bending thepipe when it has not been thoroughly heated will cause the pipe to “kink.”With proper care and a little practice, the bend will form easily.Cooling the pipe with cold air or water will cause “spring back.” Allow a fewextra degrees of overbending to compensate for this phenomenom. Themaximum bending radius shall be six times the internal diameter accordingto the National Electrical Code.6
Expansion ComparisonEXPANSION / CONTRACTIONAll conduit pipe and ﬁttings expand and contract with changes intemperature. All materials’ expansion and contraction rates arerepresented by coefﬁcients of thermal expansion.PVCAluminumA general rule of thumb is that for every 100 F temperaturechange in a 100 ft. run of PVC conduit, the conduit will undergo3.6" of expansion or contraction.SteelUse of Expansion JointsIn installations where the expected temperature variationexceeds 25 F expansion joints must be used. An expansion jointconsists of two tubes, one telescoping inside another. Wheninstalling expansion joints alignment of the piston and barrel isimportant. Straps should be placed approximately one foot oneither side of the joint to ensure that any movement is directedsquarely into the joint.Rule of Thumbfor PVC Expansion 100 ft.When expansion joints are required the following steps should befollowed:For every100 F changein temperature1.

2. Determine Piston Opening:The expansion joint must be installed to allow both expansion andcontraction of the conduit run. Because installation temperatures mayvary, the piston setting must be determined. The correct piston openingis determined using the following formula:ExpansionJoint BarrelPiston (in.) max. temperature ( F) - installing temperature ( F) x 4temperature change ( F)“O” Ring GasketPistonOpeningPistonMuzzleExample:Using step 2 we determine the proper piston opening.Size(in)Compressed Length(in)Travel(in)Piston (in.) 110 ( F) - 60 ( F) x 4" 2"100 ( Therefore this piston should be opened 2 inches when the jointsare installed.Location of Expansion JointsProper functioning of an expansion joint depends on three procedures:1. The correct placement of the expansion joint.2. The proper installation of rigid PVC conduit and the expansion joint.3. The proper placement and fastening of support straps.One Expansion Joint - Figure 1If only one expansion joint is needed between two boxes, the barrel ofthe joint should be rigidly fastened close to the ﬁrst box. Rigid PVCconduit should then be loosely supported with straps, allowing theconduit to move freely as it expands and contracts.Two Expansion Joints - Figure 2If two expansion joints are needed, the joints should be ﬁrmly fastenedback to back at the center of the run. Rigid PVC conduit should beloosely supported with straps, allowing the conduit to move freely as itexpands and contracts.Two Expansion Joints (Alternative) - Figure 3Alternatively, the center of the run and the two expansion joints (locatedat the boxes) should be rigidly fastened. All other support straps shouldbe loosely fastened.Three or More Expansion Joints - Figure 4If more than two joints are needed in a very long run, they should be putin a series, one after the other. Each barrel must be rigidly fastenedwhile conduit is loosely supported with straps allowing the conduit tomove freely as it expands and contracts. When installed in a series,each section acts independently of the other. Spacing of conduitsupports must be in accordance with NEC article 347-8.8
INSTALLATION OF EXPANSION JOINTSInstallation recommendations: Expansion joints should be mounted so the piston can travel ina straight line in the barrel. If the alignment is not straight, thepiston will bind, preventing the joint from working correctly. The expansion joint barrel should be clamped tight, but theconduit mounted loose enough in its hangers to allow formovement as it expands and contracts. Kraloy nonmetallic straps are correctly sized and designed forproper support, and must be used to secure the conduit. When expansion joints are used in a vertical position, thepiston should be mounted in a downward position so dirtcannot deposit between the barrel and piston at the muzzle ofthe expansion joints.Common MistakesThree common mistakes are:1. Forgetting to use expansion joints.2. Not using enough expansion joints.3. Overtightening of support straps.It is more cost effective to use more expansion joints thanneeded, rather than too few. It is difﬁcult to correct the problemafter conductors are installed and in service. Failure toaccommodate expansion/contraction may result in pipe fracture.Installation of the One Piece Expansion Joint(OPEJ)1.
