In which industries is the bottom loading arm most commonly used, and why?
Bottom loading arms are widely used in industries that involve bulk liquid transfer, with the most typical applications in three fields: petroleum and petrochemical industry, chemical industry, and food and beverage industry. In the petroleum and petrochemical industry (such as gas stations, oil depots, refineries), it is used to load and unload gasoline, diesel, kerosene, and other flammable and explosive liquids. The reason for its extensive use is that bottom loading can effectively reduce static electricity and liquid splashing, avoiding fire and explosion risks caused by these factors.
In the chemical industry, it is used to transfer corrosive liquids (such as sulfuric acid, hydrochloric acid), toxic liquids (such as methanol, ethylene glycol), and high-temperature liquids (such as molten asphalt). The corrosion-resistant materials (such as 316L stainless steel, Hastelloy) used in bottom loading arms and the enclosed transfer mode can prevent chemical liquids from leaking and corroding equipment, and also protect the health of operators. In the food and beverage industry, it is used to transfer edible oil, beer, fruit juice, and other liquids. The food-grade materials (such as food-grade stainless steel) of the loading arm and the clean and enclosed transfer process can ensure the hygiene and safety of food liquids, avoiding pollution.
