Physical characteristics

Long Life
PEM Pipe's service life in continuous pressure is estimated to conservatively be in excess of 50 years at ambient temperature.
         

High Chemical Resistance
PEM Pipe is inert to attack by strong acids, alkalies, salt solutions, and many other chemicals. It also doesn't corrode, degrade or support biological growth.

Freedom from Toxicity, Odors, Tastes
PEM pipe is non-toxic, odorless, and tasteless. It creates no corrosive by-products, and therefore, no contamination of piped fluid keeping the taste of water unchanged. This pipe will be an ideal for potable water supply.

Light Weight/Flexibility
PEM pipe is light in weight, which makes it easy to handle, assemble, and install. Its high flexibility eliminates the need for elbows at slight bends. Also its flexibility at a low temperature enables it easy to be installed in any applications.

Heat Fusion Welding
PEM pipe adapts the heat fusion welding, a proven welding technique that provides a speedy and leak-free joint that is as strong or stronger than the pipe itself and will last the life of the pipe. And its flexibility for any shifting in the ground caused by swelling and shrinking soil or earthquakes will not damage the pipes or cause joints to leak.

Immunity to Galvanic or Electrolytic Attack
Because PEM pipe is immune to galvanic or electrolytic attack, it can be used underground, underwater, wetlands and in the presence of metals.

Strength/Durability
PEM Pipe is highly resilient, tough and durable with high tensile and high impact strength. Its Freeze resistance allows it to maintain flexibility and integrity to lower than -80. Its impact resistance, slow crack growth resistance and long service life prove it suitable for various tough applications.

Abrasion Resistance
PEM pipe is extremely abrasion resistant. With its features such as light weight, flexible, durable, leak tight, corrosive resistant to chemical, acid, salt and etc, it is ideal for conveying the aggressive materials that are associated with the mining and dredging industries such as slurry transfer and dredging applications.

Reliability
Whether for gas distribution, water distribution or sewers, PEM Pipe is highly recognized thanks to its maximum reliability and years of efficient service life.

Ease of Installation
PEM Pipe is light in weight reducing transportation, handling, and installation costs. Its advantage is that lighter equipment, smaller crew, ordinary "bedding" requirements, standard valves and flanges are needed. These benefits result in a reduced number of fittings with no restrained joints as well as easy installation.

Low Maintenance / Cost effective
Once PEM Piping system is properly selected, designed, and?installed, it is virtually maintenance free. It will not rust, pit, scale, corrode, or promote build-up on the interior. Accordingly years of trouble-free can be expected, which will keep the maintenance and labor cost very low.

Fatigue Endurance
PEM piping systems provide exceptional endurance with the ability to sustain hydraulic transients and water hammer pressure surges.

Low Friction Loss
The smooth interior surface of PEM pipe assures low friction loss and high flow rate. Since PEM pipe does not rust, pit, scale, or corrode, the high flow rate continues for the life of the piping system.
