Can you use PEX for compressed air lines?
FAQs (Frequently Asked Questions) Can PEX pipe be used for compressed air? Yeah, the right kind of PEX pipe (PEX-AL-PEX). PEX piping itself is not exactly rated for compressed air systems and is very susceptible to UV damage so it should only be used indoors and away from windows with direct sunlight.
Will PEX hold air pressure?
PEX-a pipe can withstand a burst pressure of around 800 psi (almost two times the requirement for ASTM F876, the standard specification for PEX tubing). So neither the pipe nor the fittings are weak points, making for an extremely high-performing system in domestic water and hydronic piping applications.
What is the best pipe to use for compressed air?
A great choice for compressed air piping is stainless steel because it is strong and resists corrosion. Like with copper, corrosion resistance in stainless steel piping produces a cleaner, more consistent stream of air.
Is PEX suitable for hot water?
PEX pipe is approved for residential and commercial hot and cold water distribution systems, municipal water service lines, radiant panel heating systems, hydronic baseboard heating systems, snow and ice melting systems and building services pipe.
Can you use PEX tubing for Air Lines?
Moisture retention in compressed air can impose more significant challenges on the quality of pipelines. Due to water vapor in compressed air, many metal pipes corrode, damaging the air’s laminar flow. However, there is no such problem with PEX tubing for compressed air. PEX is a dielectric material with smooth interior walls.
How much does a PEX air compressor cost?
For 15mm £2.85 typical (compressed air fittings) ordinary PEX here rated for 12bar ~ 180psi at 20C. I have PEX airlines and they work fine.
Can a PEX pipe be used for a copper line?
As compared to copper pipes, PEX pipes are flexible. Not to mention, they can be made into large coils for easy storage. Many common pipes used for compressed air, such as steel pipes and copper pipes, freeze in a cold environment. If you fear cold temperatures ruining your PEX, then do not worry because PEX is freeze resistant.
What are the issues with PEX Air Lines?
The big issue with PEX air lines is that the PEX allows moisture to stay airborne so if you had a 5 foot copper drop with a tee for your connection a foot up from the bottom of the drop and a drain at the end of the drop…It wouldn’t get rid of all the moisture but it would surely help.
