FlameTech Flame/Smoke Containment Pipe Brochure

A recent breakthrough in material technologyhas resulted in unique piping with good opticalproperties and exceptional fire performancecharacteristics.ApplicationsHarvel® FlameTech™ has been developed for use as contain-ment piping in visual leak detection systems in areas whereflame spread and smoke generation are of concern (i.e.,containment piping installed in return air plenum applications).Major building and mechanical codes require that combustiblepiping installed within an air plenum must have a maximumflame spread of 25 and a maximum smoke development ratingof 50. Based on large-scale burn testing of finished pipingproducts conducted by ULC, Harvel® FlameTech™ piping meetsthis fire performance requirement and is Listed by ULC forsurface burning characteristics.In addition to excellent fire performance properties, Harvel®FlameTech™ translucent piping offers good optical qualities.This enables its use as containment piping for high-puritypiping runs where quick identification of primary tubing andvisual leak detection are critical. Primary tubing can be readilyidentified and inspected visually through the pipe wall. Utilizinga flashlight or alternate light source greatly enhances this uniqueattribute.Harvel® FlameTech™ Containment PipingOffers the Following Benefits:• Good fire performance characteristics – low flame spread and low smoke generation during fire exposure• High heat distortion temperature• Chemical distribution tubing can be continually monitored for leaks by visual inspection• Requires fewer monitoring sensors and other costly equipment compared to conventional “opaque” systems• Good chemical resistance• Heat-formable for on-site fabrication of belled ends, sweeps and bends• Joined using conventional solvent cement joining techniques• Installs quickly and reliably using inexpensive joining tools• Compatible with conventional Harvel Clear™ PVCpiping products• Lower overall installed costs compared to alternative materialswhere fire performance requirements are a concernDimensionsHarvel® FlameTech™ piping is available in sizes from 1/2"through 2" diameters and is produced to IPS Schedule 40dimensions per ASTM D1785 as follows:1/2"3/4"1"1-1/4"1-1/2"2".8401.0501.3151.6601.9002.375.109.113.133.140.145.154.608.8101.0331.3641.5922.049.190.253.371.502.599.803NominalPipeSizeO.D.

This is a large-scale testconducted on 24-foot lengths of dry piping to evaluate flam-mability characteristics compared to known non-combustibles(asbestos cement board) and known combustibles (red oak).Harvel® FlameTech™ piping has a maximum flame spread ratingof 0 and a maximum smoke generation of 25 when tested inaccordance with this standard. Testing has shown that Harvel®FlameTech™ piping meets the maximum flame spread (25) andmaximum smoke generation (50) values for combustiblematerials installed within an air plenum as called out by majorbuilding codes. Harvel® FlameTech™ out-performs the fireperformance characteristics of alternate plastic piping materialstypically used for visual leak detection.As a listed product, each pipe length is marked with the flamespread and smoke generation values for easy identification inthe field.Contact Harvel Plastics, Inc. Technical Services Department at610-252-7355 for additional information concerning the fireperformance properties of Harvel piping products.Physical PerformanceHarvel® FlameTech™ piping is produced from an uniquetranslucent version of CPVC material that has been optimizedto address fire performance issues. As a result, this productexhibits characteristics similar to those of conventional HarvelCPVC piping with regard to joining techniques, field fabrication,chemical resistance, and other beneficial physical properties.Harvel® FlameTech™ piping is heat-formable for on-sitefabrication of belled ends, sweeps and bends. The maximumservice temperature of this product is 200°F.Joining TechniquesHarvel® FlameTech™ piping is joined using conventional solventcement joining techniques providing a quick, strong, leak tightseal. This product is intended for use in non-pressure applica-tions only, therefore either conventional Schedule 40 PVC (clear)and/or conventional Schedule 80 CPVC (opaque) molded fittingscan be solvent cemented to Harvel® FlameTech™ piping usingexisting solvent cementing techniques. CPVC solvent cement(such as IPS 713) and primer (such as P-70) must be utilizedwhen joining molded fittings to Harvel® FlameTech™ pipe (clearPVC or opaque CPVC). Details on proper solvent cementingtechniques are available and must be referenced for properassembly and optimum joint integrity.Hangers and SupportsSupport location and spacing are dependent on the pipediameter, operating temperature of the system and the locationof any concentrated stress loads (i.e., valves, and any otherheavy system components). Proper support location is criticalto ensure deflection is kept to a minimum. Hangers used musthave an adequate load-bearing surface free of any rough orsharp edges that could damage the pipe. They must also notrestrict linear movement of the system due to the effects ofthermal expansion and contraction.System DesignSystems utilizing Harvel® FlameTech™ piping are to be designedand installed using existing industry standards for the installationof rigid thermoplastic piping. Factors such as operatingtemperatures, proper support spacing, chemical resistance,thermal expansion and contraction, handling and storage, andjoining must be taken into consideration and addressed withappropriate design techniques. The use of this product to addresscode compliance issues regarding any local, state, or nationalcode requirements concerning its use is the responsibility ofthe end user. Additional information is available from Harvel.Caution AreasAlthough Harvel® FlameTech™ maintains its physical propertieswhen exposed to many substances, exposure to certainchemicals can affect the clarity of the pipe over time. Certainnitrogen-containing organics, bleaches, oxidative agents andacids may result in discoloration. Exposure to sunlight (U.V. R.)will also affect clarity. These facts should be considered andtesting under actual use conditions is recommended. HarvelPlastics, Inc. does not recommend the use of this product forpressurized fluid applications or for the transportation or storageof compressed air or gases. Standard threading or grooving ofHarvel® FlameTech™ is not recommended due to insufficientwall thickness.Asbestos CementBoardHarvel® FlameTech™Conventional PVCRed OakMaterialFlameSpreadSmokeGeneration000-2510002580-225100Temperature °F4-1/24-1/255-1/25-1/25-1/2120 140444-1/25552-1/22-1/2333-1/23-1/21604-1/255-1/25-1/266100555-1/25-1/266731/2"3/4"1"1-1/4"1-1/2"2"PipeSize2-1/22-1/22-1/2333180Maximum Support Spacing in FeetMEMBERPLASTIC PIPEAND FITTINGSASSOCIATIONHarvel® is a trademark of Harvel Plastics, Inc.© 2008 Harvel Plastics, Inc. – All rights reserved.
