What is the standard schedule designation for most pipes used in construction?

• A. Schedule 10
• B. Schedule 20
• C. Schedule 30
• D. Schedule 40

Answer: (D)

The standard schedule designation for most pipes used in construction is Schedule 40. This designation indicates a specific wall thickness relative to the pipe's diameter, ensuring that the pipes can handle a reasonable amount of pressure. Schedule 40 is commonly utilized in a range of applications, including plumbing, drainage, and structural uses, due to its balance between strength and weight. This scheduling system helps fabricators and builders select appropriate materials based on strength requirements, pressure ratings, and compatibility with various fittings. While Schedule 10, 20, and 30 pipes do exist and serve particular purposes, they have thinner walls and are typically used in less demanding scenarios, making Schedule 40 the more prevalent choice in construction settings where durability and strength are necessary.
