Acidizing corrosion inhibitor
Corrosion
Inhibitor
Protects iron and steel components in the wellbore and treating equipment from corrosive treating fluids — engineered for high-temperature acid systems.
Introduction
UBPro-160 is a specially formulated Mannich-based compound with quaternary ammonium salt-type acidizing corrosion inhibitor chemistry. Compared with traditional acidizing corrosion inhibitors, UBPro-160 offers superior dissolution and dispersion at high temperature, delivering more significant corrosion inhibition at a lower cost.
It is applicable up to 160°C in most acid solution systems, with outstanding compatibility across a wide range of treatment fluids.

Advantages
Proven superior and consistent anti-corrosion performance versus competing inhibitors at temperatures up to 160°C.
High-efficiency anti-corrosion performance with an extremely low corrosion rate at standard dosage.
Better water and acid solubility, with excellent compatibility across most acid solution systems.
Zero residual formaldehyde or other aldehyde by-products.
Free of toxic substances such as antimony trichloride.
Applicable to N80, L80, P110 and other common tubular steel grades.
Handling, Packaging & Storage
Recommended Handling
UBPro-160 disperses readily in water and acid, with a typical dosage of up to 4%.
For cross-linked acidizing systems, a compatibility lab test with the acid thickener is recommended prior to field application.
Packaging & Storage
- Packed in 55-gallon drums and IBC totes, or other packaging as requested by the customer.
- Store in a cool, ventilated place.
- Shelf life: 12 months.
