  1. Sales Representative Basic Training Program Denver, Colorado August 28-29, 2012

  2. Sales Representative Basic Training Program • PIPE MATERIAL PROPERTIES • Inherent properties of the materials from which the pipe is made. • Physical Properties (examples) • Strength • Flexibility • Impact Resistance • Chemical Properties (examples) • Resistance to corrosion • Resistance to permeation

  3. Non-Pressure Pipe • NON-PRESSURE PIPE APPLICATIONS • Waste water collection (sanitary sewer) • Storm drainage management • Highway drainage (culverts, edge & cross drains) • Ditch closing

  4. Desired Key Pipe Attributes for Sanitary Sewer Applications • ? • ? • ? • ? • ?

  5. Desired Key Pipe Attributes for Sanitary Sewer Applications • Chemical resistance to sanitary sewer environment. • Tight joints that prevent wastewater leakage into ground water and infiltration of ground water into pipe. • Withstand deep bury (8 to 35 feet) conditions. • Easy to maintain to have long leak-free life

  6. Application Related Pipe Material Properties Inherent Properties: • Tensile Strength • Modulus of Elasticity • Impact Strength Dependent Properties: • Time Dependent • Environment Dependent

  7. Comparison of Pipe Material Properties (PVC - Sewer)

  8. Comparison of Pipe Material Properties (CCFRPM - Sewer)

  9. Comparison of Pipe Material Properties (PE - Sewer)

  10. Comparison of Pipe Material Properties (PP - Sewer)

  11. Comparison of Pipe Material Properties (PVC, PE, PP, CCFRPM)

  12. Pipe Product Performance Limits • A “performance limit” is a condition that is not desired in the installed pipe that will pose a risk to the full intended function of the pipeline. • Materials from which pipe is made impose “performance limits” on the finished pipe product that are different for each material choice.

  13. Flexible Pipe ComparisonSanitary Sewer Application • PVC (Homogeneous) • Fiberglass (Composite) • PE & PP (Homogeneous) • Ductile Iron (Composite) • Composite Definition: A complex material in which two or more distinct, structurally complementary substances, especially metals, ceramics, glasses, and polymers, combine to produce structural or functional properties not present in any individual component

  25. Performance LimitsCCFRPM Pipe

  26. Performance LimitsCCFRPM Pipe

  27. Performance LimitsCCFRPM Pipe • Corrosion protection depends on exterior resin rich layer and corrosion resistant flexible interior lining. • Micro cracking of the liner reduces life do to strain corrosion. • The material and therefore the product must be designed and installed to limit strain to predict the performance life.

  28. Performance LimitsPP Sewer Pipe

  29. Performance LimitsPP Sewer Pipe

  30. Performance LimitsPP Sewer Pipe

  31. Performance LimitsPP Sewer Pipe • Joint Performance requires significant modification to ASTM D3212 • Lower Modulus of Elasticity requires a stiffener rib under the gasket and tension bands on the outside of the bell to limit material movement (creep) under the needed gasket compression

  32. Performance LimitsPP Sewer Pipe

  33. Performance LimitsPP Sewer Pipe • History of use in sewer pipe applications is limited. • 1st North American Standard for PP in a sanitary sewer pipe application was ASTM D2736-10. • 2nd North American Standard for PP in a sanitary sewer pipe application was ASTM D2764-10.

  34. Performance LimitsPVC Pipe

  35. Performance LimitsPVC Sewer Pipe • Circumferential Deflection Structural Stability • 60% Deflection w/o cracking • 30% Reversal of Curvature • Installed deflection < 7.5% => SF = 4.0

  36. Performance LimitsPVC Pipe • Chemical Resistance • Not damaged by sanitary sewer effluent • Evidenced by 50 years of sewer service use. • Not subject to strain corrosion in acid or alkali environments. • Not affected by Hydrogen Sulfide (H2S) gases that form sulfuric acid in sanitary sewer pipelines.

  37. Performance LimitsPVC Pipe • Chemicals of concern to PVC? • Industrial Solvents (Aromatic Hydrocarbons) • Acetone • Methyl Ethyl Ketone (MEK) • Methylene Chloride • Etc. • Plasticizers • Di-Octal Phalate (DOP)

  38. Performance LimitsPVC Pipe • Chemical Resistance. • Solvents: • Highly volatile (evaporate quickly) • Dilute easily in the presence of moisture • Plasticizers: • Highly volatile (evaporate quickly) • Dilute easily in the presence of moisture

  39. Performance LimitsPVC Sewer Pipe • Joint Performance • ASTM D3212 (w & w/o Imposed shear defl.) • Vacuum 22 in Hg (10.8 psig.) • Water (10.8 psig) • Reiber (ASTM D3034, F679) • Pressure joint • Non Reiber (ASTM F794, F949, F1803) • Pro-21 (30-60 inch) • Corr-21 (12-48 inch)

  40. Performance LimitsPVC Sewer Pipe • Why 7.5 % Deflection Design Limit? • Joint is water tight to 20%+ => SF>2.0 • Hydraulic capacity retained. • Possible to still apply taps if necessary. • Structural stability to reversal of curvature with SF > 4.0 = (30%/7.5%) • Good installation practice is able to be monitored thru buried pipe deflection testing.

  41. What Pipe Three Pipe AttributesAre Most Important (Sewer) • ? • ? • ?

  42. What Pipe Three Pipe AttributesAre Most Important (Sewer) • History of Successful Long Term Use. • Infiltration and Exfiltration Free. • Best Life Cycle Cost. • Best Life Cycle Assessment Rating.

  43. Successful History(PVC – Sewer) • ASTM D3034-72 (4-15 inch) - 50 years • ASTM F679-80 (18-48 inch) - 32 years • ASTM F794-83 (4-48 inch) - 29 years • ASTM F949-85 (4-48 inch) - 27 years • ASTM F1803-97(18-60 inch)- 29/15 years What is the common denominator ?

  44. Successful History(PVC – Sewer) • In Service Surveys • Periodic Video Inspection • Pipe Dig-up and Testing

  45. Longevity Case StudyHillsborough Co., FL UIM December 2008 Issue: • Hillsborough County sewer system dates back to the 1950s. The majority of the pipelines (79.8%) were installed since 1970. • More than 80% of the gravity sewer system is constructed of PVC pipe. • Nearly 98% of the PVC pipelines were observed to be in fair to excellent condition.

  46. Successful Joint(PVC – Sewer) • ASTM F477 (Gasket Materials) • ASTM D3212 (Joint tightness) • ASTM F1417 (Installation low pressure air acceptance test)

  47. Low Life Cycle Cost(PVC- Sewer) • Lowest Pipe cost. • Lowest Pipe installation cost. • Lowest Pipe repair cost. • Lowest Pipe maintenance cost. • Lowest Pipe replacement cost. • Longest Pipe life expectancy.

  48. Best Life Cycle Assessment(PVC – Sewer) • Australia • Greenest Pipe of all the options
