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.
