Pipe schedule primarily affects which property?

• A. Wall thickness
• B. Color finish
• C. Corrosion resistance
• D. Impact strength

Answer: (B)

Pipe schedule designations tell you how thick the pipe wall is for a given nominal size. That wall thickness is what governs how much internal pressure the pipe can safely carry and its overall strength, since thicker walls resist higher stresses and reduce the likelihood of failure under pressure. The schedule does not determine cosmetic properties like color finish; coating or painting defines that aspect. Corrosion resistance comes from the material and any protective coatings, not from the wall thickness alone, and while thicker walls can affect mechanical performance, the schedule’s main purpose is to specify thickness and the resulting pressure rating. So, the property primarily affected by pipe schedule is the wall thickness.
