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).

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.
