Temperature De-Rating Table
Once cement and grout has been poured to stabilize a Lotus PVC pipe, the heat which is generated from this process can at times have a negative impact on the PVC’s integrity. When performing at these elevated temperatures, the table below reflects the potential de-rating factor on a PVC’s Collapse Pressure, Burst Pressure, and Tensile Strength.
Operating Temp. (°F/ °C) | Strength De-Rating Factor |
73 / 23 | 1.00 |
80 / 27 | 0.88 |
90 / 32 | 0.75 |
100/38 | 0.62 |
110/44 | 0.51 |
120/49 | 0.40 |
130/54 | 0.31 |
149/60 | 0.22 |
155/65 | 0.12 |
