Same data applies both to oxygen&"w <br />and nwo-bamer PEX. <br />Notes: <br />1. 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 CPUC pipe With the same size (CTS) is the same. This is why push fittings can be used with all of these picas. <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 1/2" and below. <br />Pressure ratings, testing and pressure drop <br />PEX Tutting <br />Pressure Ratings <br />Pressure testing-Hydronic & Radiant Heating <br />I Pressure testing - Hot & Cold Water Plumbing <br />200°F at 80 psi <br />3 times the maximum working pressure w a minimum 11 40 <br />1,5 times the maximum working pressure but be greater than pipe's <br />180°F at 100 psi <br />psi, but no greater than 100 psi. <br />pressure rating at given temperature. <br />74°F at 160 psi <br />Duration: 30 minutes minimum, 2 hours recommended <br />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 waterfreezing during winter months. <br />4. Since PEX is a 0exibie 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 />%://yC:/Users/Fa6ma/Desktop/pex.htmi 113 <br />
