TG200 Corrosion Inhibitor for Acidification

1. Product Introduction

TG200 Corrosion Inhibitor for Acidification is a strong adsorption type high temperature corrosion inhibitor for acidification，TG201 is suitable for chromium-containing materials, TG210 is suitable for carbon steel materials. It can be firmly adsorbed on the metal surface to form a multi-layered network dense protective film, which blocks the contact between the acid liquid and the metal substrate, resulting in no pitting. The maximum applicable temperature of Type II reaches 160 ℃. It is used for the anticorrosion of pipelines and equipment in the acidification construction process of oil and gas wells and injection wells. There is a special effect on the protection of Cr-containing tubing materials under high temperature acidification environment.The product has been certified as the independent innovation product by CNPC and it is widely used in western oil fields such as Tarim Oilfield.

3. Core Advantages

Rapid film formation, excellent temperature resistance.

4. Scope of application

This product is used for anticorrosion of pipelines and equipment in oil and gas wells and injection well during the acidizing construction process. There is a special effect on the protection of Cr-containing tubing materials under high temperature acidification environment.

5. Usage

The recommended dosage is 3.0 % main agent + 1.5% auxiliary agent at 120~140 °C and it is 4.0 % main agent + 2.0 % auxiliary at 160 °C. The inhibitor can be directly added into the acid solution, and after mixing, it can be operated as the normal acidification process. If the concentration of the acid solution is too large, the amount of corrosion inhibitor should be appropriately increased under the guidance of the technician.
