How to choose the material of the loading arm for different media?
The loading arm features flexible rotation, good sealing performance, and high technical content. It is widely used for filling tank trucks with liquefied hazardous chemicals such as liquid chlorine, liquid ammonia, caustic soda, dimethyl ether, liquefied petroleum gas, and gasoline/diesel. It enables the safe and environmentally friendly transportation of fluid media, eliminating accidents like explosions in flexible hoses that frequently occur during the filling of liquefied hazardous chemicals, which can cause casualties, economic losses, and safety/environmental issues. What should be considered when selecting a loading arm for various media?
In the petrochemical industry, there is a wide variety of liquid materials, and it is necessary to choose the appropriate materials for the loading arms. However, this standard cannot fully list detailed material selection clauses. The choice of materials should be based on the transfer pressure, temperature, and environmental conditions where the loading arm will be installed. The material should be selected based on these factors. For ordinary non-corrosive petrochemical liquids, high-quality carbon steel pipes are typically used.
It is crucial to maintain the purity of petrochemical liquids and prevent corrosion contamination. The pipes of the loading arm should be made of stainless steel. When liquid materials are directly used in the food industry, the loading arm pipes should also be made of stainless steel.
