Tips about Stainless Steel Acid Tanker Semi Trailer 2022-02-16

Large amounts of hazardous substances and chemicals, such as acids, endanger human health and harm the environment as a whole. These acids would have to be transported to various locations throughout the world. In that case, transporting the acid would necessitate the use of an acid tanker, and what could be a better choice than Stainless steel Acid Tanker semi-trailer


What is the definition of an Acid Tanker (Semi-Trailer)?


An acid tanker is a vessel that transports acids such as sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, and acetic acid, among others, for industrial purposes. Acids have different chemical and physical properties. Different acids necessitate the use of different materials in the construction of their respective tankers in this case. It is not necessary, however, to have a different type of tanker for each type of acid.


Why are Stainless steel tanks the better option when it comes to transporting chemicals like Acid?


Its wide range of application. Stainless steel tanks are widely used in food, beverage, dairy, medicine, cosmetics, and other manufacturing processes that require cleanliness and purity. In industrial plants, these are also used to store chemicals and gases where chemical resistance is required. Stainless steel is a type of iron alloy that contains a certain percentage of chromium, which gives the metal corrosion resistance. Corrosion resistance is achieved by depositing a thin layer of metal oxides that acts as a barrier against corrosive materials.

Since stainless steel is chemically resistant, it cannot be easily corroded by substances such as dilute sulfuric/hydrochloric acid.

The formation of a very thin, passive chromium oxide layer on the surface prevents further chemical action on the metal alloy, which makes stainless steel a perfect match for chemicals like acid. Because this protective film remains intact, no corrosion can occur under these conditions. 

The treatment procedure used on acid tankers can ensure that stainless steels are rustproof. 

Steel, low carbon content is used to keep welds from corroding. Carbon typically binds to chromium to form chromium carbide in the heat-affected weld zone, lowering corrosion resistance in that region.


The inner part of the steel Stainless Steel Acid Tanker Semi Trailer tank


The inner of the tanker is made of Polyethylene (PE) to prevent further corrosion. This shields the inner part from environmental reactions caused by the surrounding air, which could result in corrosion. Polyethylene (PE) is suitable for many types of acid because it is not corroded by dilute sulfuric acid or hydrochloric acid. The inner parts of the acid tankers are made of Linear Low-Density Polyethylene (LLDPE) or High-Density Polyethylene (HDPE) for this application.


The safety tips for the Stainless Steel Acid Tanker Semi Trailer


Standard safety checks and procedures should be performed on all chemical tank trailers. The service lives of these storage tanks are typically estimated to be between 20 and 40 years. A storage tank's thickness should be tested at least once every two years, and an internal inspection should be performed at least once every five years, to ensure safe operation. Numerous damage mechanisms can cause a storage tank to deteriorate and fail.


As a result, these checks are critical for assessing the condition of the initial tank surface quality, which is required to prevent this deterioration
