Overview of Schedule 40 Pipe
What is Schedule 40 Pipe?
Schedule 40 pipe is a classification of pipe that indicates the wall thickness and pressure rating. The “Schedule” refers to the strength and thickness of the pipe wall. Schedule 40 pipes are commonly used in various applications due to their balance of strength and weight.
Common Materials
- Carbon Steel: Known for its strength and durability, carbon steel pipes are often used in high-pressure applications.
- PVC: Lightweight and corrosion-resistant, PVC pipes are excellent for drainage and plumbing systems.
- CPVC: Similar to PVC but designed for higher temperatures, CPVC is suitable for hot water systems.
- Galvanized Steel: Coated with zinc to prevent corrosion, these pipes are often used in plumbing and structural applications.
