The fittings include tee's and adjustable elbow's for use with 1 1/2" and 2 " IPS pipe. These fittings are the 5EX-8 tee and 5EXT-8 tee for 1 1 /2" IPS pipe and the 5X-9 tee and 17X-9 adjustable tee/elbow for 2" IPS pipe.
The ability to withstand uplift caused by wind loads is critical in solar pipe racks. While most regions of the United States must design for 90 mph winds, certain coastal areas such as South Florida and the Gulf Coast must design for 135 mph and higher wind speeds.
On a Speed-Rail fitting, the component that produces pipe holding power is a single integrated proprietary internal/external reverse-knurl cup-point set screw that securely attaches the fittings to the pipe, and provides tremendous resistance to loosening and pullout.
The new fittings are designed with two set screws in the vertical barrel, set at 90 degrees to one another, producing a substantial increase in pullout resistance. Testing on the 1 1/2" IPS fitting shows the addition of the second set screw increases pullout capacity from 1315 pounds for the 1 set screw design, to 2080 pounds for the new 2 set screw design, both on galvanized pipe, an increase of 60 percent.
Speed-Rail slip-on pipe fittings are used with aluminum, galvanized steel, stainless steel or black iron pipe to easily and cost-effectively build solar panel racking systems. They are strong and lightweight, and come in a wide variety of fixed and adjustable configurations, including the tees and flanges most commonly used in solar panel installations.
The versatility of the fittings allows dependable support structures to be constructed virtually anywhere a solar panel needs to be installed. The same versatility also allows the systems to be easily uninstalled and moved if necessary.
All Speed-Rail fittings are made of 535.0 aluminum-magnesium and are the most corrosion resistant fittings on the market. They are backed by a 10-year warranty against corrosion, will not rust, and can be used with galvanized steel or other metals without concern for galvanic corrosion.
A Speed-Rail fitting and pipe solar rack system installs quickly, securely and cost effectively, especially when compared to welded and other more complex systems. The only tools needed for assembly are a saw, hex key and tape measure.
