The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. It is defined as the minimum temperature in which the oil has the ability to pour down from a beaker.

The pour point indicates a liquid’s lower temperature properties.If the surrounding temperature is less than the pour point, it cannot be transferred through a pipeline.The pour point is more significant for Lubricating oils.Pour points provide the lowest temperature for that fluid at which it can transfer by pouring.There are two methods for measuring the pour point of a liquid; the Manual method and the Automatic method.
The pour point for Crude oils ranges from 32 °C to below −57 °C (90 °F to below −70 °F). Some typical values of the Pour Point are provided below in the table:
Factors that directly affect the pour point of crude oil are 1. Temperature differential 2. Paraffin wax content 3. Flow rate 4. Surface Properties 5. Viscosity Due to the presence of high content of high molecular weight components, such as waxes, asphaltenes, and resins, Heavy and extra-heavy crude oils normally have higher pour points. The pour ...
Learn what pour point is, why it is important, and how it is measured for liquids like crude oil and petroleum fractions. Find out the typical values and factors that affect the pour point of different oils.
What is Pour Point? The pour point is the lowest temperature at which oil flows in a specified lab test. Specifically, the pour point is 3℃ (5℉) above the temperature at which the oil shows no movement when a lab sample container is held horizontally for 5 seconds.
Definition: Cloud point refers to the temperature at which small solid particles or crystals start to form, while pour point represents the lowest temperature at which a substance can still flow or be poured.
Pour point is defined as the lowest temperature at which the test fluid can be poured under the prescribed test conditions. It is one of the properties that determine the low temperature fluidity of a lubricating oil. Scientific Fundamentals.

The pour point of a crude oil, or a petroleum fraction, is the lowest temperature at which the oil will pour or flow when it is cooled, without stirring, under standard cooling conditions. Pour point represents the lowest temperature at which oil is capable of flowing under gravity.
pour point. 1. n. [Drilling Fluids] The lowest temperature (in degF or degC) at which a liquid remains pourable (meaning it still behaves as a fluid). Oil or synthetic muds with high pour points may suffer from poor screening and excessive pressure surges in deepwater wells or other operations subject to low temperatures.
