The PEX tube is intended for hot and cold potable water distribution systems. While defective manufacturing problems are slowly becoming a thing of the past, other issues have arisen to replace them. PEX water pipe is considered freeze-resistant but that does not mean that its completely freeze-proof. While the process prevents the pipes from bursting at the time, PEX pipes can only expand and contract so many times before it causes impactful stress on the pipes. And pros don't want a callback to fix their own work on their dime. Air pressure testing is recommended over water for practical reasons and due to difficulties arising from water freezing during winter months. Dimensional data is subject to manufacturing tolerances and may vary by brand. However, plastic PEX fittings are cheaper, easier to install, and are suitable in situations where the water transported is acidic. [3]. Their advantages and disadvantages make them ideal for use in diverse circumstances. When the water flowing through brass fittings has high zinc content, zinc leaches out into the water. Because brass can withstand higher temperatures as compared to plastic fittings, they are recommended for such installations. For instance, plastic PEX fittings pressure rating is 160 psi at 73oF. Keep reading to find out whether PEX tubing or flexible PVC . We write about "all things plumbing," helping you navigate common questions, repairs, and the best plumbing products on the market. Brass fittings are superior in strength and last longer than plastic in some instances. PEX pipe does not usually burst thanks to its maneuverability. PEX plastic is a recent material to be used in the plumbing system. to PPI Technical Notes 52 and 53 on the use of PEX tubing for high temperature nonpotable applications (see Sections 1.1, and 1.3) . As a consumer, the fittings you choose to use ultimately depend on the type of installation, budget, and personal preference. 4. Since PEX expands and contracts with temperature changes, it should be secured so as to provide sufficient space for expansion to occur. to 60 in.] It is always recommended that you survey the market first to avoid making costly mistakes. Want to tackle more plumbing projects? Some manufacturers recommend "conditioning" of the system, or allowing the PEX system to stay pressurized for about 30 minutes prior to taking a reading. They are better insulators against heat loss than metal. Content PEX 101: Everything You Need . It is a type of flexible tubing with the same sizing as regular PVC and that can be attached to PVC fittings with flexible PVC cement. Plastic PEX fittings are OK I f you're concerned about using plastic fittings instead of metal for PEX, worry no more. This option is available at no additional cost! Same data applies both to oxygen barrier and non-barrier PEX. permanent operating temperature 70 C 70C 70C Max. This means that making a connection is as simple as sliding the tubing over the fitting and tightening a metal ring around the connection. The heat from heat-producing tools such as blowtorches can damage plastic PEX pipes and fittings.

Plastic Pipes - Maximum Operating Temperatures Piping materials like ABS, PE, PVC, CPVC, PB, PP and SR and pressure and operating temperature limits. However, they are designed to withstand freezing temperatures better than metal piping due to their ability to expand. They corrode quickly when exposed to acidic environments. Similarly, a joint formed by fittings of the same material will ensure that it reacts to the surroundings the same way. There are numerous types of products and tools to use when working with PEX plastic fittings vs. brass for piping systems. The maximum working pressure for PVC piping is above 150 psig for all pipe sizes through 8 in., but this is only for temperatures of 73 F or below. Cross-linked Polyethylene (PEX) is a synthetic plastic product manufactured from high or medium-density polyethylene. Constant freezing can lead to plumbing leaks. A PEX supply won't corrode like copper. One product, PEX. Fittings that are not suitable for central heating have a maximum temperature of 65C. Pipe connections need to work correctly if the entire piping system is to be effective. For concrete slabs, pressure is maintained at 30 psi during the pour and is monitored to assure integrity of the system. 4 PEX can be ground down and reused (does not include being used in the extrusion process); PE-RT can be ground down and reused (including being used in the extrusion process). In a plumbing project, the PEX is able to stand a maximum heat of up to 180 degrees Fahrenheit. In case the pipes are used indoors, consider covering your windows using a UV protective film. Manufacturers trust them as well; the warranties for plastic fittings are similar if not identical to those for their metal counterparts. Q. In fact, PEX tubing remains flexible and can still be bent at temperatures below -40F (-40C). See this post for where we cover the advantages of PEX plumbing. In that time, he has absorbed so many slivers and ingested so much sawdust that he's practically made of wood. Manufactured in Cullman, AL. Orders with Free Ground Shipping also qualify!

Such products are intended for use in high pressure storage vessels, water distribution systems, waste drainage and sewerage systems, agricultural drainage and septic tank leach fields, and existing sewer and conduit rehabilitation. Since water expands upon freezing, this elastic property is beneficial during a freeze event, as the pipe can expand with the water." When underground, it takes longer for the material to freeze. Brass pipe fittings come in a diversity of thread sizes and shapes. Professional plumbers are buying three times more plastic than brass. to 65 in. PEX piping freezes at 20 degrees when underground. The Corzan CPVC compound has been pressure rated in accordance with ASTM D2837 and PPI TR-3 having Hydrostatic Design Basis (HDB) of: 4000 psi at 72F (23C) as listed in PPI TR-4. Additionally, when the water in the PEX plastic pipes and fittings is over-chlorinated, it causes problems. These plastic pipe standards help product manufacturers, industrial processing plants, plumbing companies, and other users and producers of these products to ensure proper and safe fabrication, assessment, installation, and utilization. This helps prevent immediate damage since the pipes expand to accommodate the ice inside as it expands. Got Plumbing Questions? PEX-a pipe, which features the highest degree of crosslinking for the greatest flexibility and durability, will burst in the 800 psi (pounds per square inch) range, which is nearly double the minimum requirement of ASTM F876 Standard Specification for Crosslinked Polyethylene (PEX) Tubing. For instance, plastic fittings are considered suitable for installations that convey acidic or poor-quality water.

However, internal plumbing can also freeze, especially if the residents go on vacation and leave the heat turned off. PEX tubing fittings are popular in plumbing systems because they are superior to ordinary plastic. Freeze Resistant Pipe expands and contracts as water freezes and thaws within pipe. Plastic fittings for PEX piping are better and more effective than their brass counterparts in some circumstances. PE - Polyethylene Plastic Pipes Temperature Derating Diagram Example - Higher Temperature and Reduced Strength If the operating pressure for a 6" Schedule 80 CPVC pipe is 167 psi, the maximum operating pressure at 150 oF (66 oC) is reduced to (167 psi) 0.5 = 83.5 psi Sponsored Links Related Topics Many people are upgrading from copper to PEX thanks to these advancements. PEX tubing is SDR9 with standard hydrostatic pressure ratings of 160 psi at 73F (1105 kPa at 23C) and 100 psi at 180F (690 kPa at 82C). This contributes to PEX lasting longer than other materials that immediately crack. Proper installation and care of PEX plastic systems and fittings are necessary to ensure they operate optimally. Copyright PlumbingNav.com 2023 Different types and sizes of fittings are used to connect PEX pipes. If youre concerned about using plastic fittings instead of metal for PEX, worry no more.

PEX piping is one of the best options for cold weather conditions as they have more flexibility. They have a conductor short-circuit rating of 250 C. Uponor PEX-a pipe expands at a rate of 1.1" (27.94 mm) for 100 ft. (30.48 m) of pipe for 10F (5.56C) temperature change. So PEX pipe holds up well under cold weather conditions and cold water, but how does it hold up to heat? 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. OD of PEX, copper and CPVC pipe with the same size (CTS) is the same.
