17 Initial Design Evaluations Round Is Best ~25 MPa ~9,5 MPa ~138 MPa Same amount of material and flow rate Stress in pipe with square section is approx.14,5 times higher than the round section. Celanese FLUID HANDLING APPLICATIONS

18 Initial Design Evaluations Round Is Best ~72 MPa ~68 MPa ~31 MPa ~5 MPa 18

19 Initial Design Evaluations Wall Thickness Instead of Ribs ~166 MPa Ribs to increase pressure resistance Better: distribute volume of the ribs evenly on surface: small reduction in overall stress level, dramatic reduction of peak stresses. ~68 MPa ~53 MPa ~50 MPa 19

1966 ~1998 Understand the operating conditions and design appropriately to avoid failure

28 Conclusions POM and PPS have a proven track record in potable water applications around the world. Nov ~1998 Understand the operating conditions and design appropriately to avoid failure will occur. Don t forget the traditional techniques. In most cases Round is best. Look at threads and tightening techniques closely. Talk to the material experts. 28
