Dimensions and Weights for Specifying Corzan® CPVC

Any system should be designed in accordance with the manufacturer’s instructions and any compliance standards. Manufacturers’ specification sheets offer insight into a material’s pressure and flow requirements, friction loss, operating temperatures, support spacing, anchoring, bracing and thrust blocking, joining methods, thermal expansion and contraction and more.

Dimensions and Weights

Corzan® CPVC pipe and fittings are available in Schedule 40 and 80 iron pipe size (IPS) dimensions from 1/4-inch. through 24-inch. Dimensions and weights for Schedule 40 and Schedule 80 piping variations are shown below:

Definitions and Derivations 

Piping design engineers can use the data above to estimate loads, stresses, torques, and other mechanical data. Following variables and equations can be used to define these values.

t: Minimum wall thickness of the pipe in inches as specified by ASTM F441 - Standard Specification for Chlorinated Polyvinyl Chloride (CPVC) Plastic Pipe, Schedules 40 and 80.

Aw: Cross-sectional area of the pipe wall in square inches.

Cross-sectional area of CPVC pipe wall in square inches

D: Outside diameter of the pipe in inches as specified by ASTM F441.

Af: Cross-sectional area of flow in pipe in square inches.

Cross-sectional area of flow in pipe in square inches

d: Average inside diameter of the pipe in inches calculated by considering theaverage wall thickness to be the minimum wall thickness plus half the tolerance allowed by ASTM F441. All the values in the above tables are calculated with the average inside diameter, not the minimum wall thickness. 

W: Average weight of pipe, in pounds per foot.

Average weight of pipe, in pounds per foot

Ao: Outside surface area of the pipe in square feet per foot. 

Outside surface area of a CPVC pipe in square feet per foot

Ww: Average weight of water in pipe, in pounds per foot. 

Average weight of water in pipe, in pounds per foot

Ai: Inside surface area of the pipe in square feet per foot. 

Inside surface area of the pipe in square feet per foot

KA: Radius of gyration about the longitudinal axis of the pipe, in inches.

Radius of gyration about the longitudinal axis of the pipe, in inches

IA: Moment of inertia, in inches to the fourth power, (in4). 

Moment of inertia, in inches to the fourth power
