Pressure Drop FRICTION FACTOR n NEW: w AIR-PRO w IRON n AGED: w AIR-PRO w IRON n C = 150 C = 100 TO 110 C = 150 C = Decreased Decrease is due to Internal Corrosion, Pitting and scaling
Pressure Drop Comparison Metal Air - Pro L= 200 m p= 12 bar V= 40 l/s result: pipe dimension: ID= 53, 0 mm OD= 60, 3 mm 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= 0. 335 psi pressure drop: Dp= 0. 210 psi ðDifference of pressure drop ~26%
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 longterm 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/mm 2 Design life of 50 years
Pressure vs. Temperature Values based on 20 mm-110 mm Socket Fusion Material
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
Design Criteria – Gooseneck Drops Removal of condensation in drops/branches
