HARVEL LXT ®

MaterialsHarvel LXT® piping is produced from an innovative PVC compound

that has been specifically formulated to reduce leachable contaminationwhen exposed to ultra-pure water environments. Minor ingredientsnecessary for processing have been scrupulously selected to addresstheir potential for contamination, and are then carefully blended inprecise ratios. This results in a much cleaner material than conventionalPVC compounds, and compares favorably to alternate materials typ-ically used for UPW piping applications. This has been validated withextensive static and dynamic leach studies during exposure to 18.2megohm ultra-pure water conducted by a reputable third party. Referto testing data on the following pages for comparative evaluation ofleachable contaminants obtained from common UPW piping materials.

Harvel LXT® material meets the toxicological requirements ofNSF International Standard 61 as being safe for use in potable waterapplications, and also complies with the provisions of Title 21 of theUnited States FDA Code of Federal Regulations as being safe for usein food contact applications.

ProcessingProcessing conditions for converting this material into pipe form

are as critical as the selection of the material itself to ensure that thephysical properties of the finished product are optimized. Correctprocessing techniques ensure proper dispersion and fusion of thecompound, resulting in a homogenous melt with uniform properties.Great care is also taken during this process using proprietary techniquesto address surface finish characteristics. Optimizing processingconditions and providing smooth internal surfaces greatly reduce thepotential for extractable and particle contaminants.

Harvel LXT® pipe is cut square, purged to remove shavings, sealedin polybags and boxed on-line at time of manufacture to minimizecontamination.

JoiningThe Harvel LXT® system utilizes a one-step solvent-cementing

system specifically formulated for use with this product (Harvel LXT®

One-Step Cement). Unlike conventional PVC solvent cements, thissystem contains fewer contaminants and cures quickly, reducing thepotential for TOC contamination. Joining is accomplished quickly andefficiently utilizing inexpensive tools, thereby greatly reducing laborand installation costs.

Physical PropertiesAlthough the extractable contaminants of Harvel LXT® piping are

much lower than those of conventional PVC piping, the physicalproperties are very similar. As a result, these products exhibit the well-known physical characteristics and other benefits of conventional PVCpiping, such as good chemical and corrosion resistance, low thermalconductivity, high strength-to-weight ratio, good impact resistance,and ease of installation.

ResistivityResistivity measured 17.95 megohms at the start of the leach and rosequickly to 18.12 megohms during the first 6 minutes. Resistivity readingscontinued to rise until reaching the background level of 18.2 megohmsafter five hours of leaching.

Dynamic Leach AnalysisHarvel LXT® piping was subjected to on-line dynamic flow analysis

with 18.2 megohm UPW to evaluate particles, TOC, resistivity, anions,cations, and trace metals. This testing utilized solvent-cemented flangeassemblies (spool piece) to see the effect that the cement had on TOC, resistivityand particle generation in a freshly assembled pipe section. Grab sampleswere also pulled periodically (at start-up, five minutes, 50 minutes and

Static Leach AnalysisDetailed extractable analysis is conducted on piping samples after

seven-day static leach utilizing 18.2 megohm ultra-pure water at ambienttemperature. Static leach of large pipe samples (120-square-inch wetsurface area) is representative of a piping system “off-line” for an extendedperiod of time. Under these conditions the effects of UPW can beextremely aggressive, severely affecting the amount of leachablecontaminants present within the piping material.

• All samples pre-rinsed identically with UPW prior to test.• Independent Laboratory Extractable Analysis

Product Ratings and CapabilityHarvel LXT® piping is produced to Schedule 80 dimensions in strict accordance

with ASTM D1785, and exhibits a Type II pressure rating. Harvel LXT® fittings areproduced to Schedule 80 dimensions per ASTM D2467. Joining of product producedto the dimensional requirements of these standards ensures that strong connectionswith good pressure-bearing capability can be made up quickly and consistentlyusing common, inexpensive tools. Utilizing these dimensions provides a higherpressure-bearing capacity compared to other “clean” systems on the market, andpermits the use of standard socket dimensions.

As with all schedules of thermoplastic pipe, pressurerating is dependent on the pipe diameter as well as theoperating temperature of the system. As temperatures rise,the pressure rating of the system decreases. The maximumtemperature rating of Harvel LXT® piping is 140°F. Smaller-diameter piping can withstand higher pressure than large-diameter piping at elevated temperatures. Use appropriatetemperature de-rating factors to determine maximumallowable pressure at elevated temperatures.

Hangers and SupportsProper support spacing is critical to ensure that deflection is kept to a minimum.

Support location and spacing is dependent on the pipe diameter, operating temperatureof the system, and the location of any concentrated stress loads (i.e., valves, flanges,test equipment and any other heavy system components). Hangers used must havean adequate load-bearing surface free of any rough or sharp edges that coulddamage the pipe during use. Hangers also must not restrict linear movement of thesystem due to the effects of thermal expansion and contraction as a result oftemperature changes; over-tightening must be avoided.

System Design & InstallationThermal Expansion and Contraction

As with all thermoplastic piping materials, considerationmust be given during the design of the system to the effects ofthermal expansion and contraction. The coefficient of linearexpansion for Harvel LXT® pipe is 3.89 x 10 –5 in./in./°F. Therate of expansion or contraction can be calculated as follows:

∆L = 12 yL (T)

Where:∆L = amount of expansion or contraction in inchesy = 3.89 x 10 –5

L = length of piping run in feet∆T = temperature change °F

(T max. – T @ time of installation or lowest system temperature or maximum system temperature,whichever is greater.)

Storage and HandlingReasonable care and common sense should be used when

handling and storing Harvel LXT® piping products. Harvel LXT®

products are tough and corrosion resistant, but they should notbe dropped or have objects dropped on them. Care should beused when transporting and storing the product to preventphysical damage. Harvel LXT® products should not be storedor installed close to heat-producing sources, subjected to externalloads or overstacked when stored. The product should beinspected for any scratches, splits or gouges. Damaged sectionsmust be cut out and discarded.

These areas must be softened and penetrated

Cement coatings of sufficient thickness

Joint IntegrityWhen the cement coating on the pipe and fittings are fluid during

assembly, they will tend to flow together and become one cementlayer. In addition, the surfaces beneath the cement coating will be softfrom surface penetration of the cement. The softened surface areas inthe tight part of the joint will tend to fuse together. As the solventdissipates, the cement layer and the softened surfaces will harden witha corresponding increase in joint strength. The dissipation of the solventfrom Harvel LXT® One-Step Cement occurs very quickly due to its highevaporation rate. Joint strength develops more quickly in the tight(fused) part of the joint than in the looser (bonded) part of the joint.A properly assembled joint will take the required working pressurebefore the joint is fully dry and final joint strength is obtained.

Joining TechniquesHarvel LXT® piping products are easily joined by the solvent-

cementing process. Unlike conventional PVC solvent-cementingtechniques, this product utilizes a one-step solvent-cement systemspecifically formulated for “clean” applications. This solvent cementexhibits extremely fast set and cure times. When properly used, thissystem results in very short cure times prior to pressure testing, andproduces a solvent-cemented assembly with an exceptionally lowpercentage of chemical additives, reducing the potential for systemcontamination.

A thorough understanding of the solvent cement joining processand proper assembly techniques must be used during assembly of theseproducts to ensure the highest system integrity. Installers must becomefamiliar with this process prior to use.

Basic Principles of Solvent CementingHarvel LXT® components are manufactured to the dimensional

tolerances for Schedule 80 pipe per ASTM D1785, and Schedule 80socket-type fittings per ASTM D2467. When fittings are produced tothese dimensions, the ID of the fitting at the entrance of the socket islarger than the ID of the fitting at the socket bottom. The taper createdby fitting socket dimensions provides an interference fit during assemblyof the components. This provides a proven means for proper matingof components, ensuring adequate joint strength when properlyassembled.

Sufficient Application of Cement

More than sufficient cement to fill the gap inthe loose part of the joint must be applied.In addition to filling the gap, adequate cementlayers will penetrate the joining surfaces andremain fluid until the joint is assembled.

Softening and Penetration

These areas must be softened and penetrated.(This can be achieved by the cement itself.)

HARVEL LXT ®

The following points must be clearly understood to ensure satisfactoryjoints are obtained consistently.

1. The joining surfaces must be softened and made semifluid.

2. Sufficient cement must be applied to fill the gap between the pipe andfitting.

3. Assembly of pipe and fitting must be made immediately while thesurfaces are still wet and the cement is fluid.

4. Joint strength develops quickly as the cement dries. In the tight part ofthe joint, the surfaces will tend to fuse together; in the loose part of thejoint the cement will bond to both surfaces.

Harvel LXT® One-Step CementUse only Harvel LXT® One-Step Cement formulated for Harvel

LXT® applications using the appropriate size applicator. Carefully readand follow the label on the cement can, and application and cure timeinstructions thoroughly. NOTE: Dauber is supplied in pint-can lid(suitable for pipe sizes 1/2" – 1-1/4"). Dauber is supplied in quart-canlid (suitable for pipe sizes 1-1/2" – 3"). For pipe sizes 4" thru 6" use aroller equal in size to 1/2 the pipe diameter.

Safety Precautions:Before applying cement, appropriate safety precautions should be taken.Solvent cement should be stored in the shade between 40°F and 110°F.Eliminate all ignition sources. Avoid breathing of vapors. Use only with adequateventilation; mechanical ventilation or local exhaust is recommended to maintainvapor concentrations below exposure limits. In confined or partially enclosedareas an organic vapor respirator is recommended. Containers should be kepttightly closed when not in use, and covered as much as possible when in use.Avoid frequent contact with skin. Wear clean rubber gloves; do not perform workwith bare hands.

Component Preparation:All pipe, fittings and tools used for joining must be clean and free of dirt, moisture, grease orother contamination prior to and during the joining process.

Cutting:Cutting the pipe as squarely as possible (90°) is required, as it maximizes the bonding area of thejoint. Only sharp wheel-type cutters with blades specifically designed for cutting plastic shall beused. Cutters should be rotated slowly to provide optimum cut. Cutting speeds should be furtherreduced at lower temperatures. The use of a saw is not recommended as filings and shavings willcause particulate contamination.

Deburring:All pipe ends shall be properly chamfered by providing a 10° to 15° bevel (1/16" to 3/32" in width).A chamfering tool designed for this purpose shall be used. A proper bevel will aid in assembly andprevent solvent cement being pushed from the wall of the fitting during assembly. Burrs and filingscan prevent contact between the pipe and fitting and must be removed from the outside and insideof the pipe during this process. A common practice is to place sterile gauze in the pipe end toprevent shavings from entering the pipe. The gauze is then removed prior to cement application.

Joining Preparation:A. Prior to assembly, all components shall be inspected for any damage or irregularities. Mating

components shall be checked to assure that tolerances and engagements are compatible. Do notuse components that appear irregular or do not fit properly.

B. Check the dry fit – The pipe should enter the fitting socket easily one-quarter to three-quartersof the way. If the pipe bottoms in the fitting with little interference, use extra solvent cement inmaking the joint.

C. Measure the socket depth of the fitting and mark this distance on the pipe end. This referencemark can be used when joining to ensure the pipe is completely bottomed into the fitting duringassembly.

Solvent Cement Application:Harvel LXT® One-Step Cement shall be applied to the joining surfaces using a dauber or natural-bristle brush approximately half the diameter of the pipes being joined. Working quickly, apply aheavy, even coat of solvent cement to the pipe end on the surface equal to the depth of the fittingsocket. Apply a light coat to the fitting socket. If there was little interference during the dry fit, applya second coat of cement to the pipe end at this time. Great care must be used to prevent cementfrom coming into contact with the interior waterway of the fitting or pipe.

Assembly:Immediately insert the pipe into the fitting socket while rotating one-quarter turn. Properly alignthe fitting for the installation at this time. The pipe must bottom completely to the fitting stop. Holdthe assembly for approximately 30 seconds to ensure initial bonding. Due to the taper on theinterference fit, the pipe can back off the fitting stop if steady pressure is not held on the joint duringinitial bonding. A bead of cement should be evident around the pipe and fitting juncture. If thebead is not continuous, it may indicate that insufficient cement was applied. Due to the uniquetranslucency of Harvel LXT®, visual inspection of the cemented joint can be conducted utilizing aflashlight or alternate light source. Joint integrity can be readily verified by visually inspecting thecemented surfaces for uniformity. If insufficient cement is applied, the joint must be cut out, discardedand begun again. Excess cement must be wiped off from the pipe OD using a clean rag at this time.

Installation Notes:Installers should verify for themselves that they can make satisfactory jointsunder varying conditions.

Use the appropriate size applicator. Avoid puddling of solvent cement onor within fittings and pipe. This will cause excessive softening of materials,resulting in damage to the product and excessive system contamination.

Harvel LXT® solvent-cemented assemblies cure very quickly when properlyconstructed, enabling pressure-bearing capability in a short time. This isa positive attribute of the system for scheduling pressure tests and repairwork. However, Harvel Plastics, Inc. recommends that newly assembledsystems be allowed to cure for a minimum period of 24 hours prior tosystem rinsing/activation procedures. This reduces the potential for TOCcontamination.

Harvel LXT® piping products should not be connected directly to UV lightsources that can expose system components to ultraviolet radiation. ContactHarvel technical support for additional information at 610-252-7355.

to a minimum. Harvel does not recommend flow velocities in excessof five feet per second.

Harvel LXT® piping systems are not formulated for outdoor use. Prolongedexposure to ultraviolet radiation (UVR) will affect physical properties.

Harvel Plastics, Inc. recommends that newly installed systems be allowedto cure for a minimum period of 24 hours prior to rinsing proceduresto reduce the potential for TOC contamination. Rinsing procedures,chemical rinse and other cleanup/disinfection procedures to be usedare at the discretion of the system design authority.Note: Harvel LXT® piping is compatible with hydrogen peroxide atconcentrations up to 30% at 73°F. Contact Harvel for additional chemicalcompatibility information concerning the use of Harvel LXT® productswith various substances prior to use.

Set and Cure Times:Set and cure times are a function of pipe size, temperature, pressure,humidity and tightness of fit. The initial set time is the recommendedwaiting period prior to handling a newly assembled joint. After theinitial set time, the joints will withstand the stresses of normalinstallation. (Misalignment of components during assembly will causeexcessive stress in the joint, which can affect joint integrity). Thecure time is the recommended waiting period prior to pressurizingnewly assembled joints. Minimum cure time prior to pressure testingis dependent on pipe size, temperature, humidity, tightness of fit andtest pressure required. Longer cure times must be allowed whenworking at higher humidity and colder temperatures.
