China Suppliers Factory Direct Drag Reducing Agent UBPro-471 to Enhance Pipeline Throughput and Profitability
Product introduction
UBPro-471 is a Drag Reducing Agent (DRA in short).
- Designed to increase flow rate or to reduce pressure drop in the pipelines delivering crude oil.
- As an ultra-high molecular weight polyalphaolefin dispersed in a non-aqueous base / carrier. Drag reduction begins as soon as DRA starts to dissolve in the hydrocarbon being delivered.
- When dissolved DRA product passes through a boosting pump the polymer is broken down or worn out by the shearing exerted by the boosting pump. Consequently, a multi-stationed pipeline usually requires repeated DRA injection after each boosting pump station in order to achieve overall flow increase through the whole pipeline length.
- It does not degrade during normal pipeline flow, but is designed to degrade when passing through mainline pumps or other high-shear regions. This shear degradation eliminates the need to process the treated oil farther downstream.

Applications/Functions
- Used in a wide ambient temperature envelope ranging from -20 to +50℃.
- Dissolves quickly in hydrocarbons, Increased flow rates.
- Extended pipeline lifespan.
- Reduced energy consumptions.
Advantages
- Achieve greater than 70% drag reduction under certain conditions
- Low temperature(-20 ℃)：Propylene Glycol improve the fluidity of the drag reducer at low temperatures (such as preventing freezing) and enhance the overall stability of the formula.
- Handle and inject into the pipeline easily and with minimal safety risks
- Increase pipeline throughput at the same operating temperature
- Improves pipeline capacity without capital investment
Recommended Handling
- Injection rate depend on: performance required, viscosity, wax/water content of the oil, etc.
- The injection point is between the station the metering skid and the external pipeline enters the ground. This can avoid the shear of the external pump impeller and the flow meter’s interception and stirring action. And the drag reducing agent has enough distance to meet the requirements of dispersion time. The DRA injection skid includes injection pumps, flow meters, and pressure gauges. The pneumatic chemical agent injection pump is used to introduce the instrument wind as the power source.
- The recommended dosage is required for optimal results by a pilot test.
- All personnel handling this material must handle it as an industrial chemical, wearing protective equipment and observing the precautions as described in the Material Safety Data Sheet (MSDS).

Frequently Asked Questions
What is UBPro-471 and what is it used for?
UBPro-471 is a Drag Reducing Agent (DRA) designed to increase the flow rate or reduce pressure drop in pipelines delivering crude oil. It is an ultra-high molecular weight polyalphaolefin dispersed in a non-aqueous carrier base.
How does UBPro-471 behave under high-shear conditions like pumps?
UBPro-471 does not degrade during normal pipeline flow. However, it is designed to degrade when passing through mainline pumps or high-shear regions. This shear degradation eliminates the need for downstream processing to remove the agent. Consequently, multi-stationed pipelines require repeated injection after each boosting pump station.
What are the key technical properties of UBPro-471?
It is a white or light grey liquid with an alcoholic odor. It has a specific gravity of 0.85~0.90 (at 20℃), a freezing point of -30℃ Min, a flash point of 60℃ Min, a maximum viscosity of 400 mPas@50s-1, and an initial boiling point of 160℃.
Where is the recommended injection point for the Drag Reducing Agent?
The injection point should be located between the station metering skid and where the external pipeline enters the ground. This position prevents the shear degradation caused by the external pump impeller and the flow meter's stirring action, while providing sufficient distance for dispersion.
How does UBPro-471 perform in low-temperature environments?
UBPro-471 can be used in a wide temperature range from -20 to +50℃. It contains Propylene Glycol, which improves the fluidity of the drag reducer at low temperatures (preventing freezing) and enhances the overall stability of the formula.
What are the packaging and storage options for UBPro-471?
It is standardly packaged in 1000L IBCs, with alternative packaging like ISO tanks available upon request. It should be stored in a dry, well-ventilated area with containers kept closed, following standard safe warehousing stacking and palletizing practices.
