What type of material should be used for sleeves in wet conditions?

Using SCH 40 PVC pipe for sleeves in wet conditions is appropriate because this type of material is designed to resist moisture and has good durability against typical environmental factors one might encounter in wet areas. PVC (Polyvinyl Chloride) is inherently resistant to corrosion, which makes it suitable for use in conditions where it may be exposed to water or other liquids.

Additionally, SCH 40 indicates the wall thickness and pressure rating of the PVC, suggesting that it can withstand significant external forces while maintaining its integrity in wet environments. The non-conductive nature of PVC also adds a safety component, reducing the risk of electrical hazards in wet settings. This makes SCH 40 PVC pipe a commonly preferred option for sleeves in such conditions, ensuring both durability and safety.
