    Slip Joints & Flange-to-Flange Joints

    Coupling: Use standard C-1-F coupling or, in the fi eld, cut a short length of spiral pipe.

    Pipe to Pipe slip joint

    Flange to Flange Joint

    Spiral pipe is designed to be easy to install: all pipe ends are female, and all fi tting ends are male, allowing pipe and fi ttings to easily slip together. There are several methods of joining Spiral pipe and fi ttings, depending on your application and your applications requirements.

    Slip Joints Slip joints are the simplest method of joining Spiral pipe:

    Fitting-to-fi tting joints (male to male) require a separate coupling, C-1-F; or a short, hand-cut section of Spiral pipe can be used as a coupling for quick, in-the-fi eld connections.

    Pipe-to-pipe joints (female to female) also require a separate C-1 coupling.

    Pipe-to fi tting joints slip together without the need of a separate coupling.

    Slip joints are fastened with screws or pop-rivets, and duct sealant or sealant tape (page 27) when additional air tightness is required. (The screws or rivets hold the pipe in place as the sealant cures.) The standard recommendation is for screws or pop-rivets to be used at a maximum of 15 intervals with no fewer than three screws or pop-rivets per joint. Spiral Manufacturing recommends a maximum interval of 6.

    Flange-to-Flange JointsFlange-to-fl ange joints are widely used to connect pipes in dust and fume control applications, in outdoor applications, and for additional strength in high positive or high negative pressure applications. Flange-to-fl ange joints are fastened with bolts for permanent installations and for installations where the pipe must mate with fans or other air moving equipment. Flange clamps are used when there is a need for frequent, or occasional, maintenance or cleaning. Flange ends are fabricated by using angle rings (p. 25) to create a Vanstone Flange connection (p. 24).

    No Coupling: Pipe sections (female) and fi ttings (male) are sized to slip together.

    Coupling: Use standard C-1 coupling. The C-1 coupling is also used with fl exhose.

    Step 1

    Slip fl ange over Spiral ductwork allowing duct to extend 1/2 beyond the face of the fl ange. Measure to ensure the fl ange is square to the duct. Secure fl ange in place with 3 or 4 C-clamps.

    Step 2

    Peen 4 tabs about 1 wide and 90 apart, work-ing from the inside of the fl ange. The edge of the fl ange acts as a break. Do not cut, slice, or ham-mer directly on the end of the duct.

    Step 3

    Rotate duct 45 and peen 4 more tabs about 1 wide and 90 apart. There should now be a total of 8 tabs bent over.

    Step 4 Peen remaining edge of duct over fl ange. Flange is ready to be bolted.

    Field Installation ofVanstone Flanges

    SpiralmateSpiralmate fl anges are airtight and easy to install, and no additional sealants are required. They can be installed on-site, they are easy to align, and they use a one-bolt closure. Spiralmate fi ts Spiral seam and most ribbed pipe, and it accommodates moderate variations in pipe diameter.

    Spiralmate is available in diameters from 8 to 72 in 2 increments. For one-inch increments and sizes larger than 72, consult the factory.

    The Spiralmate system is comprised of four components: two fl anges with integral mastic injected into the duct receiving pocket, a gasket, and a closure ring and bolt. See photo on page 25.

    Spiral Manufacturing offers professionally mounted Vanstone fl anges on Spiral pipe and fi ttings. For most installations, this is the easiest and most secure option. There may be times, however, when Vanstone fl anges must be mounted at the installation site. We have included mounting instructions below to assist you.
