Single-Wall Spiral Pipe & Fittings
Sheet Metal Connectors, Inc. (SMC) Single Wall Pipe and Fittings with Complete Seal, E-Z Flange and Barrel Clamp or Standard Slip Connection
Single-Wall Spiral Pipe
Sheet Metal Connectors, Inc. spiral pipe is formed from a coil of metal into a rigid steel tube with a 4-ply spiral lockseam. It has a smooth interior for low friction loss with the grooved seam entirely on the outside. This pipe has a resistance to crushing approximately 2 1/2 times that of longitudinal loc5"kseam or welded pipe. Optional corrugations are available which increase the rigidity of the pipe by approximately 300%. Pipe sections can be joined together by an Complete Seal Spiral Pipe Connector, E-Z F5l"ange with Barrel Clamp, E-Z Flange Jr. with Bar5re" l Clamp, Standard Spiral Pipe Connector, or Companion Angle Rings.

Single-Wall Connectors
Complete Seal Fittings 6" to 24" Diameter
Complete Seal fittings are manufactured from galvanized steel meeting spec ASTM A-653 (Lockforming quality). They feature a double legged EPDM gasket which creates a virtually airtight connection when slipped into spiral pipe. The gasket is mechanically attached to the fitting with a 180 degree hemmed edge. This hem gives added rigidity to the fittings, ensures that the gasket will never slip out of place and makes a safe rounded edge for the installer. *Complete Seal is currently available on Galvanized Fittings only.
E-Z Flange with Barrel Clamp 26" to 96" Diameter
The E-Z flange with barrel clamp can be factory installed or shipped loose for field installation. A set consists of two E-Z flanges and one barrel clamp. For field installation the installer attaches the E-Z flange to the pipe and fittings. Next the installer applies the gasket to one flange, mates the two flanges together and attaches the barrel clamp. Sheet Metal Connectors can also install E-Z flanges. Flanges are spot welded and internally sealed on all ends of the spiral pipe and fittings.
E-Z Flange Jr. with Barrel Clamp 6" to 24" Diameter
The E-Z flange jr. is a 5/8" flange turned out 90? on each end of the spiral pipe and fittings. The installer applies a gasket on one flange, mates the two flanges together, and attaches the barrel clamp. For field cuts a 5/8" flanged sleeve is available. Trim the spiral pipe to the measured length and attach the sleeve.
Standard Spiral Pipe Connector
Pipe to Pipe connections are made by using a fitting size coupling that slips inside the mating pipe sections. A stop bead runs around the middle of the coupling to center the coupling in the connection. Secure the connection by installing sheet metal screws through the outer shell of the duct, 1/2 inch from the stop bead.
Companion Angle Rings Pressed and Rolled
Companion angle rings are for end connections whenever a smooth interior surface or intermediate stiffening is required. Rings are manufactured from mild steel. Companion angle rings can be factory installed or shipped loose. Companion angle rings can be attached by solid weld, tack weld, or van stone connection. See companion angle ring size chart on page 20.
