Can the NurailŪ aluminum fittings be used with steel and stainless steel pipe?

Although most aluminum alloys will corrode when combined with a dissimilar metal (i.e. steel, black iron, stainless steel), the aluminum/magnesium alloy 535 which Hollaender uses to manufacture all cast fittings is the most corrosive resistant casting alloy available and can be used with any type of metal.

Have NurailŪ Fittings been tested in corrosive environments?

Yes, NurailŪ standard fittings have been tested for 1000 hrs. of salt spray (per ASTM B117 specifications) after which the set screws could still be removed and retightened. In addition, NurailŪ fittings' corrosion resistance to Hydrazine Fuel has also been tested by the United States Air Force prior to the products' use at Cape Canaveral Air Force Station and the Kennedy Space Center. Not only have our products been tested in the laboratory, but they have also stood the test of time for over forty years in some of the most corrosive environments including: chemical plants, offshore oil rigs, waste water treatment plants, pulp & paper mills, etc.

If I have an extremely corrosive environment, are there any additional coatings or features that are available for the fittings to insure that the installation performs and continues to look good for a long time?

The standard material is highly corrosive resistant, however, for the most extreme environments, we recommend that the fittings be anodized and that stainless steel set screws be used. The anodizing process creates a coating, which is not only harder and more corrosive resistant than the base metal, but also provides significant resistance to staining.

Should the fittings be used in a chlorine rich environment?

No, the chlorine aggressively attacks the aluminum, which can result in significant deterioration of our product. Our recommendation would be to use reinforced fiberglass railing in this environment.

What does IPS mean?

IPS stands for "Iron Pipe Size" - A standard which was originally developed for fluid transfer has also become the standard for handrail systems, both steel and aluminum.

What wall thickness should be used with NurailŪ fittings?

The actual wall thickness you select will depend on the type of system you are assembling, however, the wall thickness should never be less than the minimums listed below.

Steel Pipe - Schedule 40
Aluminum - Schedule 40

What pipe materials can I use with NurailŪ fittings?

Any metal pipe (including galvanized steel, stainless, black iron, aluminum, etc.) can be used with our slip-on fittings as long as it is sized properly (see above). Plastic, FRP and thin wall sleeve should never be used unless a reinforcing dowel is also used inside the pipe.
