In which part of new tanks are wear plates installed?

1. Inside the tank

2. Above the product level

3. Below all accessible openings

4. On the external surfaces

The correct answer is: Below all accessible openings

Wear plates are installed in new tanks specifically below all accessible openings. This placement is crucial because these areas are typically subject to the highest risk of wear and abrasion due to fluid movement and pressure. The wear plates provide a protective barrier, extending the life of the tank and maintaining its integrity by absorbing impact and reducing direct wear on the tank material. The selection of this location is rooted in both practical considerations of tank maintenance and operational safety. By positioning wear plates in these critical areas, operators can ensure that any maintenance required is easier to conduct, thereby enhancing the tank's functional lifespan and reducing repair costs over time. Other locations mentioned, such as inside the tank or above the product level, do not offer the same level of protection from wear and might not adequately address the wear concerns associated with external factors or pressurized environments. Additionally, while considering the external surfaces could offer some protection, it does not directly address the high-impact zones where wear is most likely to occur.
