Polyethylene Pipe for Compressed Air Applications
Clearing Up Confusion

In trade publications there appears to be considerable confusion about the use and installation of polyethylene pipe in compressed air applications according to Mike Stahmer, Chairman of the AusPoly Technical Committee.

In compressed air applications polyethylene PE 100 and PE 80B are recommended and used extensively, whereas PE 63 and PE 80C are not normally recommended. Standards Australia has published the revised version of AS/NZS 4130, Polyethylene (PE) pipes for pressure applications.

Field Butt Welding of Rural or Thin Wall Poly pipe
A Potentially Expensive Mistake

Simple butt welders are now being offered to the farming market to weld rural or thin wall metric poly pipe and offer the promise of reducing the expenses associated with purchasing mechanical joiners/couplers.

These butt welders run the risk of producing welds which may fail prematurely. Polyethylene pipe appears to be a very forgiving material initially, however, any polyethylene system is only as good as the joints. If the joints are not made with the correct equipment and procedures the joints have a much higher chance of premature failure.
