PEX tubing sizes are denoted by CTS(copper tubing size),not OD(Outside Diameter)or ID(Inside Diameter). <br /> 2. OD of PEX,copper and CPVC pipe with the same size(CTS)is the same.This is why push fittings can be used with all of these pipes. <br /> 3. PEX made to US standards must comply with a SDR-9(Standard Dimension Ratio),which is the ratio of OD(Outside Diameter)to pipe wall thickness <br /> (9:1).Exceptions are nominal sizes 112"and below. <br /> Pressure ratings, testing and pressure drop <br /> PEX Tubing Pressure testing-Hydronic&Radiant Heating Pressure testing-Hat&Cold Water Plumbing <br /> Pressure Ratings <br /> 200"17 at 80 psi 3 times the maximum working pressure or a minimum of 40 1.5 times the maximum working pressure but no greater than pipe's <br /> 180°F at 100 psi psi,but no greater than 100 psi. pressure rating at given temperature. <br /> 74°F at 160 psi 1 <br /> 1 Duration:30 minutes minimum,2 hours recommended Duration:30 minutes minimum,2 hours recommended <br /> Notes: <br /> 1. Maximum working pressure indicates highest anticipated operating pressure. <br /> 2. Pressure testing requirements and procedures should be in compliance with local codes and PEX manufacturer's instructions. <br /> 3.Air pressure testing is recommended over water for practical reasons and due to difficulties arising from water freezing during winter months. <br /> 4. Since PEX is a flexible pipe,it will expand somewhat(especially PEX-a)during the initial pressurizing of the system,causing a drop in pressure reading. <br /> Some manufacturers recommend`conditioning"of the system,or allowing the PEX system to stay pressurized for about 30 minutes prior to taking a <br /> reading. <br /> 5. For concrete slabs,pressure is maintained at 30 psi during the pour and is monitored to assure integrity of the system. <br /> file:///C:AJsers/Fatima/Desktop/pex.htmt 1 r3 <br />
