9/6/2015· PEX-a is regulated by ASTM F876, which denotes a maximum temperature rating of 200 F at 80 psi. The latter is well within the range of operation for the vast majority of hydronic systems. Also, because of its copper tube size (CTS)-controlled outside diameter, switching to PEX-a piping involves minimal process change.
I am obsessing over which pex to use for a whole house manifold installation. The choices are pex-a (uponor) vs pex b (viega). Uponor seems easier to work with, less kinking, better flow etc. What I am most concerned with is: 1.longevity (this is my forever house) 2 ...
10/2/· When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corrode. Freeze resistance. It’s resistant to freezing (once again, due to its flexibility, which allows the PEX piping’s diameter to expand as the water pressure changes).
Stiffer than PEX-a but, less than that of PEX-b Compatible connection types with PEX-c are: ASTM F1807, F1960, F2080 & F2159 PEX-AL-PEX Is a multi-layer pipe made of two PEX layers with a continually laser welded aluminum layer in the center. The
13/9/· PEX Pluing Pipe Advanes PEX pluing pipe offers several advanes over traditional pluing pipe materials. Because it is made with a flexible and resilient material, PEX is more resistant to breakage caused by freezing than both copper or PVC pipe.
Note that unlike many PEX pluing pipe brands, Everhot Non-Barrier PEX meets ASTM F2023 for chlorine resistance with 2.0-5.0ppm concentration at pH level of 6.8-8.0 (standard conditions for RO, de-ionized or tap chlorinated water) and according to the
Replacement options include PVC, CPVC, copper or PEX tubing. For years copper has been the dominant format, showing up in as much as 80% of all new construction homes in the past 30 years, but CPVC is a steady force and certainly popular with remodelers and do-it-yourselfers since it doesn’t involve sweating and soldering pipes.
ASTM F877 standard PEX is for water service of 100 PSI and with a maximum working temperature of 180 F (82 C). F877 standard tubing should be able to withstand a temperature of 210°F (98.9°C) at 150 PSI for a short period (around 48 hours).
5/12/· The PEX, XPE or XLPE pipe is a thermoplastic pipe made by cross-linking of high-density polyethylene polymer which is cheaper, tougher and better than PVC or copper. These pipes are the modern era in the pluing system owing to their flexibility, resistant to freezing, temperature changes, UV rays, chlorine, corrosion, etc.
PEX is also lightweight, flexible, easy to transport and install, and built to be long lasting. Like copper, it can carry hot water without melting. There may even be environmental benefits: production, use and disposal of PEX products uses far less energy ands produce ...
5/12/· Brass (ASTM F1807 standard) Poly alloy (ASTM F2159 standard) Both of them are compatible with any PEX tubing (type A, B, C) and brands. Method of Connection Crimp method: To connect a PEX pipe with a fitting, this method requires a crimp tool 2.
PEX-a pipe can withstand a burst pressure of around 800 psi (almost two times the requirement for ASTM F876, the standard specifiion for PEX tubing). So neither the pipe nor the fittings are weak points, making for an extremely high-performing system in …
PVC is thought to be better at muffling the sound of running water. In most North China markets, the two types are priced similarly. Where significant price differences can be found, it’s usually due to higher shipping costs for one type. Working with ABS or ...
19/7/· PEX crimp fittings are the standard type of fitting used in PEX systems. A large variety of fittings are available to make PEX-to-PEX connections, as well as transitions to other pipe materials. Most crimp fittings are made of brass (manufactured to ASTM F1807 standards), but poly-alloy crimp fittings (sometimes called poly-plastic ) are also available (manufactured to ASTM F2159 standard…
There are 4 classifiions of PEX Pipe, known as PEX-a, PEX-b, PEX-c and PEX-d/PEX-other. This topic can be explored in greater detail below or in our subsequent article. Each classifiion refers to the method of inducing crosslinking in the polyethylene chain, and results in different strength, shape memory and flexibility characteristics.
One of the popular aspects of fire sprinkler installations that is overwhelmingly familiar to fitters in the field yet something I hardly understood back as a new graduate is pipe connections. Today I'm breaking out some of the popular methods of joining HDPE pipe in fire
When designing for a 100 years life, PVC usually is required to withstand 60% deflection while Fiberglass is supposed to withstand only 20% deflection. According to Diamond Plastics, “PVC by standard has a 7.5% recommended allowable deflection no matter what size or stiffness; whereas fiberglass has a limit of 3% due to deflection and strain limitations on its PS72 products,”
For example, CPVC solvent cements must meet ASTM F493 specifiions, and PVC solvent cements must meet ASTM D2564 specifiions. Because of this, CPVC and PVC pipes and fittings, along with their solvents and bonding agents, should not be used interchangeably.
ASTM F876 and ASTM F877 manufacturing standards incorporate benchmarks for chlorine resistance to ensure PEX pipe can withstand the potential oxidative effects of heavily chlorinated water. Uponor AquaPEX pipe meets the highest requirement per ASTM F876 and F877 for chlorine resistance at end-use conditions 100 percent of the time at 140°F (60°C).
14/6/2013· PVC or CPVC - That is the Question The first difference between PVC and CPVC pipes that people notice is usually that extra “c,” which stands for “chlorinated” and affects the uses of CPVC piping. There is also a significant price difference. Even though both of ...
PVC and CPVC-type drain, waste or vent pipe and fittings installed underground or under or through slabs, driveways, patios, foundations, etc., must be Schedule 40 meeting ASTM D2665 (or better) and identified by proper markings.
Some pex fittings are made of a type of durable plastic known as polyalloy. Examples: These fittings appear to be plastic equivalents of their brass counterparts. In general is it permissible to use either the copper crimp rings OR the stainless HDPE cinch / pinch

Which is better, copper or plastic pipe? This article describes the pros and cons of using copper or plastic piping in buildings. We explain the advanes and possible downsides of choosing one or the other (plastic piping or copper piping for water supply or drains).
PEX or PEX-lined pipe has wide code acceptance across the country, but PEX requires special fittings and is not recyclable. The chemical crosslinking required to produce PEX adds expense, and increases the potential for contaminant migration from plastic to water.
These are PEX A, PEX B and PEX C. In hindsight, that's an unfortunate naming scheme, because it makes it sound like these are grades and implies that one is better or worse than the other. They are actually types of manufacturing processes to achieve a finished product.
There are several approved standard specifiions for PEX connections; ASTM F 1807, ASTM F2159, ASTM F2080, and ASTM F 1960. All of these standards reference permanent mechanical insert fittings of various configurations.
