Massachusetts Oil Burner License Practice Test

What is the recommended method for protecting buried oil lines?

1. Leave them exposed

2. Encapsulate with concrete

3. Use metal piping

4. Sleeve in plastic or PVC pipe

The correct answer is: Sleeve in plastic or PVC pipe

Using a sleeve in plastic or PVC pipe is the recommended method for protecting buried oil lines because it provides a barrier that helps prevent corrosion and physical damage. This protection is essential for maintaining the integrity of the oil lines and ensuring safe operation over time. The plastic or PVC material is resistant to moisture and chemicals, which reduces the risk of leaks or failures that could occur due to environmental factors. Encapsulating with concrete is not ideal, as it can lead to issues with moisture retention and makes it difficult to access the lines for repairs or inspections. Similarly, while metal piping is durable, it is susceptible to corrosion when buried without adequate protective measures. Leaving the lines exposed offers no protection at all and significantly increases the risk of damage, whether from weather elements or physical impacts.
