In the industrial sector, 98% sulfuric acid is a commonly used strong acid, employed in various applications, including chemical engineering, metallurgy, and mining. Choosing the right pump to transport 98% sulfuric acid is of utmost importance, but whether it's safe to use 304 stainless steel pumps for handling this potent acid remains a topic of concern. This article will delve into this matter to help you understand the relationship between 98% sulfuric acid and 304 stainless steel pumps.

Characteristics of 98% Sulfuric Acid:98% sulfuric acid, also known as concentrated sulfuric acid, is a highly concentrated sulfuric acid solution. It possesses extremely high acidity and corrosiveness, demanding caution during handling and conveyance.

Characteristics of 304 Stainless Steel:304 stainless steel is a common stainless steel material frequently used to manufacture various equipment and components. It exhibits good corrosion resistance, but it's not suitable for all strong acidic mediums.

Can 304 Stainless Steel Pumps Safely Transport 98% Sulfuric Acid?While 304 stainless steel has decent corrosion resistance in some acidic mediums, there are crucial considerations when dealing with 98% sulfuric acid:

Concentration and Temperature:98% sulfuric acid is a highly concentrated acid and is typically used at elevated temperatures. Under such conditions, 304 stainless steel may corrode, making it unsuitable for prolonged transport of concentrated sulfuric acid.

Corrosiveness:98% sulfuric acid exerts corrosive effects on stainless steel materials, especially at high temperatures and concentrations. This may lead to material degradation and a decline in pump performance.
Material Selection:For applications involving the transport of 98% sulfuric acid, it is more appropriate to choose special alloys like Hastelloy C, which offer higher corrosion resistance, particularly under extreme conditions.

While 304 stainless steel performs well in some acidic mediums, it may not be the best choice for transporting highly concentrated and high-temperature 98% sulfuric acid. To ensure the safe and reliable transport of 98% sulfuric acid, it is advisable to select materials with superior corrosion resistance, such as special alloys. Proper pump material selection will contribute to improved production efficiency, reduced maintenance costs, and enhanced workplace safety. When choosing pump materials, rely on professional knowledge and experience to make the best selection decision possible.
