China Suppliers Factory Drag Reducing Agent UBPro-471 to Boost Pipeline Throughput and Flow Rates
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.

Key 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.
CapEx Efficiency: Improves pipeline capacity without capital investment.
Recommended Handling
- Injection Rate: Injection rate depend on: performance required, viscosity, wax/water content of the oil, etc.
- Injection Point: 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.
- Dosage Determination: The recommended dosage is required for optimal results by a pilot test.
Safety Warning: 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 how does it function in crude pipelines?
UBPro-471 is an ultra-high molecular weight polyalphaolefin Drag Reducing Agent (DRA) dispersed in a non-aqueous carrier. It is formulated to dissolve directly into delivered hydrocarbons to reduce pipeline pressure drops and boost flow throughput.
What level of drag reduction can UBPro-471 deliver?
Under specified operational conditions, UBPro-471 can achieve greater than 70% drag reduction, significantly upgrading pipeline capacity without capital-intensive infrastructure investments.
Why is re-injection needed after booster pump stations?
While UBPro-471 maintains performance during steady pipe flow, high shear forces in booster/mainline pumps break down the polymer chains. Re-injection after each pump station maintains optimal flow rates across multi-station systems.
How does the product perform under cold climate conditions?
UBPro-471 operates efficiently within a broad ambient temperature range of -20°C to +50°C. Its Propylene Glycol formulation prevents freezing and ensures reliable fluid handling in sub-zero environments.
Where should UBPro-471 be injected into the pipeline system?
The optimal injection location is between the metering skid and where the external pipeline enters the ground, preventing mechanical shear from upstream pumps and allowing sufficient dispersion travel distance.
What packaging options are available?
Standard packaging is provided in 1000L IBC containers. Customized logistics packages, including ISO tanks, are available upon request.
