3.0 SYSTEM DESIGN
A. System design shall be in accordance with the manufacturer’s instructions.

B. Maximum design pressure ratings shall not exceed those listed in the tables below. Pressure ratings apply to water at 73°F. For temperatures greater than 73°F, see derating factors listed. For fluids other than water, the full pressure rating may not apply; see the chemical resistance table for guidelines.

C. Schedule 80 pipe operating above 130°F shall NOT be threaded. Threaded pipe shall be derated to 50% of the pressure rating for the piping at the system operating temperature.

D. Flanged systems of any size shall not exceed 150 psi working pressure at 73°F. Follow the manufacturer’s recommendations for temperature derating factors for services greater than 73°F.

E. Corzan valves are typically rated at 150 psi up to 240 psi at 73°F (pressure rating varies with valve type and manufacturer). Consult the valve manufacturer for pressure ratings and temperature derating schedules.

F. A Hazen-Williams friction factor of 150 shall be used in all hydraulic calculations.

4.0 JOINING SYSTEMS
A. Assembly of pipe and fittings shall be done by solvent cementing, threading, or flanging.

B. Solvent cement that meets or exceeds the requirements of ASTM F493 shall be used in conjunction with a primer manufactured by companies listed under section 2.0 D.

C. Flanges shall be installed on pipe ends with primer and solvent cement and then bolted together per the manufacturer’s instructions and torque ratings.

D. Threading shall be performed on Schedule 80 pipe 4" and smaller, per the manufacturer’s instructions. Only water soluble oil or water shall be used when threading pipe. Degreasing type solvents shall never be used to clean threads.

E. Only Teflon tape or CPVC compatible pipe dope shall be used when making plastic threaded connections. Lubrizol maintains a list of products that have been shown to be incompatible with CPVC piping systems. Chemically incompatible products are added to this list as they are brought to Lubrizol’s attention. For the most current list of chemically incompatible products, contact us or refer to the website, www.corzancpvc.com. A product’s absence from this list does not imply or ensure CPVC chemical compatibility. Always confirm chemical compatibility with CPVC with the manufacturer of the product in contact with the CPVC piping system.

MAXIMUM SUPPORT SPACING (FEET) SCHEDULE 80

Support spacing recommendations are based on straight runs of uninsulated lines conveying fluids with specific gravities up to 1.0. Heavy system components such as valves, flanged assemblies, tees and other forms of concentrated stress loads must be independently supported. For specific gravities greater than 1.0, the support spacing from the table provided should be multiplied by the following correction factors:

Specific Gravity	1.0	1.1	1.2	1.4	1.6	2.0	2.5
Correction Factor	1.00	.098	0.96	0.93	0.90	0.85	0.80
