What does pipe schedule indicate?

Explanation:
Pipe schedule is the designation that tells you the wall thickness of a pipe for a given nominal size. A higher schedule means a thicker wall, which increases the pipe’s strength to handle pressure and reduces the internal bore. The schedule does not specify operating temperature or material grade; those are defined separately. While wall thickness influences the allowable pressure, the schedule itself is fundamentally a designation of wall thickness rather than a direct pressure rating.
