    FLEXIBLE ALUMINUM PIPE WITH INSIDE AND OUTSIDE PE COVER

    Yellow Color

    You are bidding on the world famous gasFlex flexible gas piping. Used in Europe and Australia for over 10 years, this technology is now revolutionizing the way we pipe gas in America.

    gasFlex is a multi-layered composite tubing consisting of an interior aluminum tubing lined with inner and outer layers of UV resistant polyethylene (PE). It is a durable, reliable tubing that will not corrode or rust. The flexibility of gasFlex tubing results in easy rollouts. The stay-in-place rigid feature of the tubing makes it ideal for:

    • Interior gas piping systems
    • Underground gas piping systems
    • Running gas lines to remote areas in the yard (BBQ -Jacuzzi - Space heater)
    • gaslite systems

    FITTINGS COMPATIBLE WITH THE gasFlex SYSTEM ARE AVAILABLE ON OUR EBAY STORE EXCELAMERICA.

    ALUMINUM TUBING IS LISTED IN NFPA54

    FOR GAS USE

    If you want to know a little more about gasFlex :

    • The PE layers protect against corrosion and creates a shield so the tubing can be embedded in concrete.
    • The aluminum layer provides stiffness to hold the tubing in the desired shape and fire resistance.
    • Together, the layers make up a flexible tubing that stays in place, won't discolor and has a very low thermal expansion rate (similar to copper and steel).

    SUMMARY of ADVANTAGES


    The inner and outer layers of composite multilayer gasFlex are UV treated Poliethylene; and its middle layer is a flexible aluminum tube. gasFlex has most of the advantages metallic pipe. Its advantages are easy bending, anti-rust, non-corrosion, and fire resistance.


    gasFlex 's inner and outer layers consist of PE with U.V resistant components. At normal temperature, it does not dissolve in any known solutions and is resistant against acid, alkaline or salty soil.

    Both materials offer perhaps the best chemical and corrosion resistance of any plastic used in the manufacture of plumbing pipes. The polyolefin family of plastics PE is renowned for it's toughness, long working life and resistance to deterioration in the most extreme environments.

    On the other hand, when metal or copper pipes are exposed to aggressive soil and conditions, they are susceptible to corrosion and pitting.

    Ease of Installation

    No more copper sticks, no more sweating joints every few feet. gasFlex's convenient, lightweight coils allow you to install a professional gas piping system quickly and efficiently. Installation crews are less fatigued and larger coils mean less wastage.

    Need to make a bend ? Go ahead. Need to snake pipe around an obstruction ? There's nothing stopping you. When the system calls for a fitting, you simply cut, bevel, insert and crimp the pipe for secure, long-term connections. It's really that fast and simple.

    Go anywhere with gasFlex

    gasFlex can be installed behind drywall and above false ceilings or surface mounted. It can be supported horizontally or vertically on 8 foot centers because its stiffness and expansion rate is similar to copper's. gasFlex can be encased in concrete or buried underground without additional protection because its tough outer plastic layer resists chemicals and corrosive activity.

    Superior Flow

    gasFlex's smooth inner wall toughened with carbon black permanently resists scaling and abrasion, keeping gas flow constant year after year.

    gasFlex uses fewer fittings, in fact less than half the fittings used in a copper or black iron system. Fewer fitting joints means less chance of leakage and less liability.

    PRESSURE DROP TABLES:

    NATURAL GAS :

    Natural gas appliances work properly at a pressure between 5"WC and 8" WC . So the allowable pressure drop in your line is around 3" WC. Use the load (power) going through the line and divide by the pressure loss / foot into 3 to get the max distance. For example a barbcue grill fas a load of about 125,000 BTUH , corresponds to 125,852 in the table below,...the pressure drop for this load is 0.144. If we divide 3" WC by 0.144 , we get an allowable distance of 21 feet for your gas line in Natural gas.

    LPG GAS (PROPANE)

    LPG gas appliances work properly at a pressure between 9"WC and 11" WC . So the allowable pressure drop in your line is around 2" WC. Use the load (power) going through the line and divide by the pressure loss / foot into 3 to get the max distance. For example a gas boiler has a load of about 188,600 BTUH , ,...the pressure drop for this load is 0.027. If we divide 2" WC by 0.027 , we get an allowable distance of 74 feet for your gas line in LPG gas.
