In temperate climates, where temperatures reach sub-zero levels, water in the pipes can freeze, causing the pipes to burst. They are more durable than plastic if installed correctly. Strictly follow chemical resistance recommendations. Technical Note53 Guide to Chlorine Resistance Ratings of PEX Pipes and Tubing for Potable Water . Maximum working temperature 200F @ 80 psi. 800-818-3201 Free Shipping on orders over $99 ship free Ship To: 11234 Buy PEX Fittings Online - Poly, Brass Crimp Style 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. PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). See this post for where we cover the advantages of PEX plumbing. They are more expensive to acquire and install. Q. It tends to be too aggressive for the system, particularly at high temperatures. Although the hacksaw can get the job done, it leaves the surface with burrs which may result in improper connections. Find out, Copyright 1996 - 2023 ASTM. 93 0 obj

Poor quality brass resulting from high concentrations of zinc corrodes quickly and causes leaks in brass fittings. to Metal Insert and Plastic Insert Fittings . Polyethylene is altered to enhance its properties like stability, long-term strength, and heat resistance [1]. Anyone interested in a do-it-yourself project can put together a functional piping system using plastic PEX fittings and pipes. Lined Flexible Corrugated Polyethylene Pipe for Land Drainage Applications, F405-13 Standard Specification for Corrugated Polyethylene (PE) Pipe and Fittings (Withdrawn 2015), F667/F667M-16(2021) Standard Specification for 3 through 24 in. Maximum Safe Temperature The PEX tube can withstand a maximum heat temperature of 200 degrees Fahrenheit. A: Pressure/temperature rating is in excess of 100 psi @ 180F - per ASSE 1061 standard requirements. Minimum working temperature 33F @ 160 psi. Push-Fit or Push-to-Connect style fittings. We are no longer supporting IE (Internet Explorer). Since PEX pipe doesnt hold up as well when exposed to UV rays, PVC pipe is the better choice for outdoor plumbing as it can last longer. Also, no plastic pipe or fittings can be used within 18 in. PEX tubing and fittings connect with barbs and crimp rings. Their application in this field entails the manufacture of fuel line valves, air brakes, and hose ends. PEX, or cross-linked polyethylene, has a chemical structure that gives it flexibility to withstand pressure increases and perform better in the winter. [3]. Red PEX-B Pipe Coils | SharkBite Plastic PEX fittings and pipes are best suited for domestic plumbing installations because they are ductile. Definition Manufactured in Cullman, AL. In contrast, installations of systems that handle extreme temperature changes are not ideal for plastic fittings. The appropriate fitting in terms of material, size, and shape for the junction should be used to achieve a good connection. 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). Many plumbing codes require PEX tubing to be pressure-rated for 100 psig (gauge pressure) at 180F, so this pressure rating is considered mandatory, and is based on hydrostatic testing as described above. There are numerous types of products and tools to use when working with PEX plastic fittings vs. brass for piping systems. All pipes freeze. Fittings that are not suitable for central heating have a maximum temperature of 65C. What You Need to Know About PEX Plumbing Pipe | Family Handyman One product, PEX. Maximum working pressure indicates highest anticipated operating pressure. Many people are upgrading from copper to PEX thanks to these advancements. Consequently, it is not advisable to install such fittings in boiler rooms or near furnaces. 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. Many times, freezing temperatures affect outdoor faucets first. Acidic water tends to corrode brass fittings easily and could lead to wearing away and failure of the entire system. 4. Although some consider PEX plastic fittings as inferior to and less durable than brass, this is not quite the case. For instance, plastic fittings are considered suitable for installations that convey acidic or poor-quality water. However, PEX plumbing might not be the best option for commercial and industrial systems that use scalding water in their operations. We write about "all things plumbing," helping you navigate common questions, repairs, and the best plumbing products on the market. PEX pipes freeze when temperatures fall below freezing for exposed outdoor pipes and when temperatures fall below the temperature alert threshold for underground outdoor pipes. Flexible PVC is exactly what it sounds like. This, however, is the highest temperature the material can withstand before it starts losing strength and collapsing. Exceptions are nominal sizes 1/2" and below. Features Uponor PEX PE-RT Kink repairable P O 200F temperature rating P O Up to 3" sizes P O1 Potable listing for barrier pipe P O Compatible with ASTM F1960 fittings P O2 Wall and Fittings for Radiant Heating Systems up to 75 psig, F645-18b Standard Guide for Selection, Design, and Installation of Thermoplastic Water- Pressure Piping Systems, F2855-19 Standard Specification for Chlorinated Poly(Vinyl Chloride)/Aluminum/Chlorinated Poly(Vinyl Chloride) (CPVC-AL-CPVC) Composite Pressure Tubing, D2846/D2846M-19a Standard Specification for Chlorinated Poly(Vinyl Chloride) (CPVC) Plastic Hot- and Cold-Water Distribution Systems, D2774-21a Standard Practice for Underground Installation of Thermoplastic Pressure Piping, D1527-99(2005) Standard Specification for Acrylonitrile-Butadiene-Styrene (ABS) Plastic Pipe, Schedules 40 and 80 (Withdrawn 2014), D3309-96a(2002) Standard Specification for Polybutylene (PB) Plastic Hot- and Cold-Water Distribution Systems (Withdrawn 2010), D2282-99(2005) Standard Specification for Acrylonitrile-Butadiene-Styrene (ABS) Plastic Pipe (Withdrawn 2007), F771-99(2005) Standard Specification for Polyethylene (PE) Thermoplastic High-Pressure Irrigation Pipeline Systems (Withdrawn 2014), F690-86(2003)e2 Standard Practice for Underground Installation of Thermoplastic Pressure Piping Irrigation Systems (Withdrawn 2012), F1176-01e1 Standard Practice for Design and Installation of Underground Thermoplastic Irrigation Systems With Maximum Working Pressure of 125 psi (Withdrawn 2010), F1380-95a(2002)e1 Standard Specification for Metal Insert Fittings for Polybutylene (PB) Tubing (Withdrawn 2008), F2969-12(2020) Standard Specification for Acrylonitrile-Butadiene-Styrene (ABS) IPS Dimensioned Pressure Pipe, F480-14(2022) Standard Specification for Thermoplastic Well Casing Pipe and Couplings Made in Standard Dimension Ratios (SDR), SCH 40 and SCH 80, F1668-16(2022) Standard Guide for Construction Procedures for Buried Plastic Pipe, F878-95 Specification for Polybutylene (PB) Thermoplastic Thin-Wall Drip Irrigation Tubing (Withdrawn 2000), F877-23 Standard Specification for Crosslinked Polyethylene (PEX) Hot- and Cold-Water Distribution Systems, F2389-23 Standard Specification for Pressure-rated Polypropylene (PP) Piping Systems, F2806-23 Standard Specification for Acrylonitrile-Butadiene-Styrene (ABS) Plastic Pipe (Metric SDR-PR), F3253-23 Standard Specification for Crosslinked Polyethylene (PEX) Tubing with Oxygen Barrier for Hot- and Cold-Water Hydronic Distribution Systems. XLPE-insulated cables have a rated maximum conductor temperature of 90 C and an emergency rating up to 140 C, depending on the standard used. You can benefit from picking the right pipe material for freezing conditions (even if its a rare occurrence in your area). B137.0/B137.3; ULC S102.2-M88; NSF-PW; ASTM D1785. However, plastic PEX fittings are cheaper, easier to install, and are suitable in situations where the water transported is acidic. hbbd```b`` qd["4A$)d)j`Q0D&,
