ALLOWABLE WORKING PRESSURES

The working pressures of Pexgol pipes are based on DIN 16893-2000 and the accumulated experience of Pexgol pipes in Infrastructure and Industry including pipes that were installed 30 years ago at the Dead Sea Hot leach crystallization facility carrying Hot Sylvinite at 114 deg. C and are still working today.

The design stresses σ in tables 11.1 and the working pressures in tables 11.2 & 12.1 were calculated with a safety factor of 1.25 According to DIN 16893-2000 these values are for water.

In case of chemicals and corrosive agents, the working pressures might have to be de-rated according to the data in the chemical resistance tables.

Changes of design stress values σ with temperature:

Temperature (°C) σ (kg/cm2)
10 85
20 76
30 66.5
40 59
50° 52.5
60 48
70 42.5
80 37,5
90 33.5
95 32
100 27.5
105 22.5
110 18.75
