Angle Rings
(Pressed or Rolled Steel)

Pressed and rolled steel angle
rings are used widely in joining
ductwork together in dust and
fume control work. All rings are
unpainted, mild steel (Galvanized
and Stainless Steel available). They
are available with or without holes.
Dimensions shown are typical.
Nearly any bolt circle or hole size is
available. Consult Factory.

Field Installation of Vanstone Flanges

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

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

Step 2
Peen 4 tabs about 1” wide and 90° apart, working from the inside of the flange. The edge of the flange acts as a break. Do not cut, slice, or hammer 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 flange. Flange is ready to be bolted.
 
Spiralmate
Spiralmate® flanges 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 fits 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 flanges with integral mastic injected into the duct receiving pocket, a gasket, and a closure ring and bolt. See photo on installation components page.
