HDPE Conduit, Types, and ApplicationsHDPE Conduit Types- Example: Three-in-One HDPE conduit with innerduct- Example: Multi-color reel of 2 inch IPS conduit9 2018 Plastics Pipe Institute

HDPE Conduit, Types, and ApplicationsHDPE Conduit Benefits- Not susceptible to corrosion- Moisture-proof and water-tight- Immune to attack from insects- Resists brittleness due to aging or cold weather- Eliminates maintenance common to aerial networks- Easy installation due to long lengths and high pull strength- Low coefficient of friction allows easier long-distance cable pulls- Follows trench contours, can be installed around obstacles underground- Bends and flexes without breakage, even with ground heaves or shifts, over a widerange of temperatures- High ductility resists damage during transportation, handling, and installationand retains impact resistance10 2018 Plastics Pipe Institute

HDPE Conduit, Types, and ApplicationsHDPE Conduit Sizes- Various sizing systems exist, including IPS types SDR9, SDR11, SDR 13.5,DR 15.5, Schedule 40 and Schedule 80, "True Sized”, and SIDR- For IPS types, wall thickness is described by the Dimension Ratio (DR)*which typically ranges from DR 9 to DR 17 for diameters up to 12-inch- HDPE conduit standards such as ASTM F2160, NEMA TC 7, and UL 651Aspecify the exact dimensions for HDPE conduit*Ratio of outside diameter to wall thickness. The lower the DR number, the thicker the wall,relative to other dimension ratios. Some dimension ratios are “standard” and called “SDR”11 2018 Plastics Pipe Institute

HDPE Conduit, Types, and ApplicationsSummary- HDPE conduit and cable in conduit is availablein a wide variety of types and sizes- Used for many critical applications to protect powerand fiber optic cables to connect our modern world- Proven to be reliable and dependable- May be installed using trenching, plowing,and horizontal directional drilling (HDD)22 2018 Plastics Pipe Institute

2. History of HDPE Conduit StandardsHistory of HDPE Conduit Standards- The early driver behind the use of conduit produced from high-density polyethylene(HDPE) was for deploying and protecting fiber optic (FO) cables placed undergroundfor the telecommunications industry- Tremendous growth occurred for the installation of fiber optic cables during theearly to mid-1980s for linking major metropolitan areas together. In the mid-1980s,fiber optic cable deployment was booming, and multiple manufacturers of HDPEconduit were busy keeping up with demand- However, there were no third-party product standards in place specifically for HDPEconduit, so the industry adopted existing standards for HDPE water pressure pipes23 2018 Plastics Pipe Institute

History of HDPE Conduit StandardsExamples of typical HDPE water pressure pipe standards:- ASTM D3035 “Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR)Based on Controlled Outside Diameter”- ASTM D2239 “Standard Specification for Polyethylene (PE) Plastic Pipe (SIDRPR) Based on Controlled Inside Diameter”- ASTM D2447 “Standard Specification for Polyethylene (PE) Plastic Pipe,Schedules 40 and 80, Based on Outside Diameter” (Withdrawn 2010)- ASTM D6070 “Standard Test Methods for Physical Properties of Smooth-Wall,Coilable, Polyethylene (PE) Conduit (Duct) for Preassembled Wire and Cable”(Withdrawn 2016)- ASTM F714 “Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR)Based on Outside Diameter”24 2018 Plastics Pipe Institute

History of HDPE Conduit StandardsRisk of Using Water Pipe Standards for Conduit- Project specifications that cite inappropriate pressure pipe standards can causeconfusion with manufacturers, the supply chain and installers- While HDPE pressure pipe and conduit standards may appear similar, there aretechnical differences that are critical to the performance of the products in specificapplications- Specifying a water pipe for a conduit application may even violate requirements ofrelevant electrical codes while potentially increasing costs, with no value for thecustomer25 2018 Plastics Pipe Institute

History of HDPE Conduit StandardsRisk of Using “Customized” Specifications for Conduit- Project specifications that combine inappropriate or incompatible requirements,sometimes pulled from various sources with the best intentions, can create the needfor products that don’t exist!- Sometimes referred to as “Frankenstein specs” – “let’s use a bit of this, a bit of that”- This causes confusion with manufacturers, the supply chain, & installers, and canresult in the incorrect product being installedIs this reallywhat wasintended?26 2018 Plastics Pipe Institute

History of HDPE Conduit StandardsImportance of Using Current HDPE Conduit Standards- Industry conduit standards are continuously reviewed, maintained and revised bySDOs* with input from manufacturers through participation in organizations like PPI,which facilitates interface between manufacturers, users, and standards developmentorganizations such as ASTM, NEMA, UL, TIA and others- This continuous connection ensures that HDPE conduit standards meet the variouscode and regulatory requirements for the intended uses*SDO Standards Development Organization (e.g. AASHTO, ASTM, CSA, NEMA, UL)27 2018 Plastics Pipe Institute

History of HDPE Conduit StandardsSummary- Conduit specifications have been specifically developed for the demands oftelecomm, power, utility, aerial or underground applications- An inaccurate or an out-of-date product specification can cause confusion amongsuppliers or result in an inadequate product being installed- References to pressure pipe standards should be removed from product or projectspecifications for HDPE conduit- In other words, obsolete or inappropriate pressure pipe standards should be replacedwith the most appropriate of the current HDPE conduit standards by selecting thesingle HDPE conduit standard that is the closest match for the application28 2018 Plastics Pipe Institute

3. Industry Standards for HDPE ConduitCurrent HDPE Conduit Standards- The first ASTM standard specification written and approved for HDPE conduit wasASTM F2160 “Standard Specification for Solid Wall High Density Polyethylene(HDPE) Conduit Based on Controlled Outside Diameter (OD)”- F2160 was originally approved in 2001, then revised in 2008, and again in 2010- In 2016, a significant revision of F2160 expanded the Scope, consolidated 11dimensional tables into four, clarified test procedures, added pipe stiffnessrequirements, and revised requirements, such as resistance to slow crack growth- Revision was published as F2160-16 in December 2016 www.astm.org29 2018 Plastics Pipe Institute

Industry Standards for HDPE ConduitCurrent HDPE Conduit Standards- Today, there are seven (7) recognized standard specifications for HDPE conduit andcable in conduit for various applications, plus one “Guidelines ” document- HDPE conduit standards specify material properties, dimensions, performancerequirements and test methods for evaluating HDPE conduit30 2018 Plastics Pipe Institute

Industry Standards for HDPE ConduitASTM F2160-16: Standard Specification for Solid Wall High DensityPolyethylene (HDPE) Conduit Based on Controlled Outside Diameter (OD)“This specification covers material, dimensional, workmanship and performancerequirements for polyethylene conduit, duct and innerduct manufactured for use in nonpressure applications for the protection of fiber optic and power cables. Applicationsinclude telecom, SCADA command and control, highway lighting, ITS (IntelligentTransportation Systems) and Underground Utilities with PE conduit installed usingmethods such as Horizontal Directional Drilling (HDD),plowing and open trench.”- Originally approved 2001- Current edition approv
