Maximum service temperature is a measure indicating the maximum continuous temperature at which an insulation material can operate without any degradation in thermal insulation performance.MST is either measured according to:aximum Service Temperature (MST) under 500Pa â a guarantee that can be used for design. To estimate the highest continuous operating temperature at which a product can be used, a variety of methods exists.
Maximum Service Temperature. PVC-U and PVC-M pressure pipes are suitable for use at service temperatures up to 50Â°C. For PVC-O pipes, the maximum continuous operating temperature should be limited to 45Â°C.he coefficient of thermal expansion is 7 x 10 -5 /Â°C. A handy rule is 7 mm change in length for every 10 metres for every 10Â°C change in temperature. Example. A 150 metre line of PVC pipe is being installed with the temperature at 28Â°C. The service temperature will be 18Â°C.
