The corrosivity of high-purity hydrogen bromide

Hydrogen bromide is a highly corrosive gas that corrodes many materials, including some common metals and plastics. Due to the highly oxidizing nature of hydrogen bromide, special care must be taken when selecting pipeline materials for transporting it. Hastelloy is a corrosion-resistant alloy material that possesses excellent resistance to acids, oxidation, and heat. However, for gases containing hydrogen bromide, Hastelloy may not be the best choice. Because although Hastelloy can resist corrosion by substances such as sulfuric acid and hydrochloric acid under certain conditions, it is not very resistant to hydrobromic acid (i.e., hydrogen bromide). For hydrogen bromide at concentrations of 10–50 ppm, some special materials may be required for transportation. For example, polytetrafluoroethylene (PTFE, also known as Teflon) and polyvinylidene fluoride (PVDF) are two possible options, as both of these materials can resist corrosion by hydrogen bromide to a certain extent. However, the most important thing is to make a choice based on the actual conditions, because in addition to hydrogen bromide, other factors such as temperature, pressure, and concentration also need to be taken into account. Therefore, it is recommended that you consult a professional materials scientist or chemical engineer to determine the material that best suits your needs. .

Are there detailed specifications such as temperature and type of medium?

It is recommended to use PE pipes for transfer to ensure minimal corrosion while maintaining the appropriate moisture levels

The medium used by the original poster is actually high-purity hydrogen bromide containing 10–50 ppm of hydrogen bromide? How do you define a high-purity dielectric?

By 10-50PPm, you mean in water, right?
