4. Ductility California-OSHA Pressure Testing: Impact Testing
Quick Burst Pressure Test
1000 Hour Pressure Test
Impact Testing
Sharp, Object Strike -Pressurized
Blunt, Object Strike -Pressurized
Object Strike -0 F -Pressurized

5. Ductility MODE OF FAILURE Cal-OSHA Compliance
SMALL LINEAR TEARS
Cal-OSHA Compliance
Non-Catastrophic Failure Mode

6. Chemical Resistance Resistance to Mineral and Synthetic Compressor Oil
Resistance to wide range of Chemical and Vapors
No solvent joining cements to worry about!

7. Pressure Drop FRICTION FACTOR NEW: AGED:
AIR-PRO C = 150
IRON C = 100 TO 110
AGED:
IRON C = Decreased
Decrease is due to Internal Corrosion, Pitting and scaling

8. Pressure Drop Comparison
Metal
L= 200 m
p= 12 bar
V= 40 l/s
result:
pipe dimension: ID= 53,0 mm
OD= 60,3 mm
pressure drop: Dp= psi
Air - Pro
L= 200 m
p= 12 bar
V= 40 l/s
result:
pipe dimension: ID= 53,0 (54) mm
OD= 72,6 (75) mm
pressure drop: Dp= psi
Difference of pressure drop ~26%

9. Stress Curve
The calculated service life of pipe is based on the results of the creep rupture tests under internal compression carried out by the material manufacturers as per DIN 8075, and on long-term tests of the ageing stability in temperature controlled oxygen fresh water.
MRS 10: minimum required strength for an operating time of 50 years and a temperature of 20°C = 10 N/mm2
Design life of 50 years

10. Pressure vs. Temperature
Values based on 20mm-110mm Socket Fusion Material

11. Design Criteria – Thermal Expansion
L = 12 LT
L = Change in Length (inches)
=Coefficient of Thermal Expansion
L = Length of pipe run
T = Change in Temperature

12. Design Criteria – Gooseneck Drops
Removal of condensation in drops/branches
