China Drag Reducing Agent 471 Suppliers & Factory for Enhanced Pipeline Throughput and Flow Rate
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).
Packaging and Storage
- 1000L IBC. Supply in other packing such as ISO tanks can be offered upon request.
- Store in dry, well-ventilated area. Keep container closed. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and /or stacking.
Frequently Asked Questions (FAQ)
What is UBPro-471 and how does it function?
UBPro-471 is a Drag Reducing Agent (DRA) containing ultra-high molecular weight polyalphaolefin dispersed in a non-aqueous carrier. It is designed to dissolve quickly in crude oil pipelines to reduce pressure drop and boost flow rates.
Does this drag reducing agent degrade in the pipeline?
UBPro-471 is stable and does not degrade during normal pipeline flow. However, it is designed to degrade when subjected to high-shear forces, such as passing through mainline pumps, which removes the need for downstream removal processes.
What are the primary technical indexes of UBPro-471?
Key specifications include a white or light grey liquid appearance, alcoholic odor, specific gravity of 0.85~0.90 (at 20℃), freezing point of -30℃ Min, flash point of 60℃ Min, and a maximum viscosity of 400 mPas@50s-1.
Can UBPro-471 be used in extreme temperatures?
Yes, it works within a wide ambient temperature range of -20℃ to +50℃. The addition of Propylene Glycol ensures the product maintains fluidity and formula stability even at low temperatures down to -20℃.
Where should the product be injected into the pipeline?
The recommended injection point is between the station metering skid and where the pipeline enters the ground. This position protects the agent from the high shear of pump impellers and flow meters, allowing enough distance for optimal dispersion.
What are the available packaging and storage options?
The standard package is a 1000L IBC, though ISO tanks can be provided upon request. It should be stored in a dry, well-ventilated warehouse with containers tightly closed.
