wallthickness
Wall thickness is the distance between the inner and outer surfaces of a hollow object, such as a pipe, tube, vessel, or tank. It is typically measured in millimeters or inches and is a fundamental factor in determining an object's strength, stiffness, weight, and ability to contain internal pressure. In piping and pressure vessels, wall thickness together with diameter or radius dictates pressure rating, with thicker walls generally enabling higher internal pressures. Wall thickness is often specified through standardized systems such as pipe schedules (for example, Sch 40, Sch 80) or by explicit thickness values in vessel designs.
Measuring and assessing wall thickness rely on several methods. Direct measurement uses calipers or micrometers for
Design, standards, and maintenance considerations. Wall thickness is chosen based on service loads, material strength, allowable
