What temperature range should glass-lined equipment be expected to serve?

The minimum temperature allowance for a standard glass-lined steel reactor is -20°F (-29°C).

For cryogenic processes that require even lower temperatures there are special models that can be designed to accommodate temperatures as low as -76°F (-60°C). The maximum temperature is 500°F ( 260°C).

Another factor to take into account is temperature change limitations. This refers to the allowable temperature differential between the vessel walls and the product. Simply put, if you put something into a reactor and the temperature of the product varies too greatly from the temperature inside the reactor you can cause a lot of damage.
