1Single-Wall Spiral Pipe & FittingsSheet Metal Connectors, Inc. (SMC) Single Wall Pipe and Fittingswith Complete Seal, E-Z Flange and Barrel Clamp or Standard Slip ConnectionSingle-Wall Spiral PipeSheet Metal Connectors, Inc. spiral pipe is formed from a coil ofmetal into a rigid steel tube with a 4-ply spiral lockseam. It hasa smooth interior for low friction loss with the grooved seamentirely on the outside. This pipe has a resistance to crushing5"approximately 2 1/2 times that of longitudinal lockseamorwelded pipe. Optional corrugations are available which increasethe rigidity of the pipe by approximately 300%. Pipe sections canbe joined together by an Complete Seal Spiral Pipe Connector,5"5" Clamp,E-Z Flangewith Barrel Clamp, E-Z Flange Jr. with BarrelStandard Spiral Pipe Connector, or Companion Angle Rings.5”5"Lateral section of 4-ply pressure-proof spiral seam.5”5"Lateral section of grooved seam with optional corrugated grooves.55”Optional culvert groove.Single-Wall �� - 96”Galvanized26 - 14 gaugeA-653G60-G901’ – 20’, 10’ Standard3” - 96”Paint Grip24 - 18 gaugeA-653A601’ – 20’, 10’ Standard3” - 96”PVS*24 - 16 gaugeA-6534 x 1, 4 x 41’ – 20’, 10’ Standard3” - 60”**Aluminum.032 - .063B-3163003 H-141’ – 20’, 10’ Standard3” - 60”**Stainless Steel24 - 18 gaugeA-240304 or 3161’ – 20’, 10’ Standard*PVS specification book available** Call factory for sizes over 60” in diameter.Single-Wall FittingsElbow Lock SeamSMC spiral fittings are manufactured with an elbow lock seam, lapseam (i.e. stitch weld, riveted, tack weld or solid weld), standingseam or butt weld seam.

2Single-Wall ConnectorsComplete Seal Fittings 6” to 24” DiameterComplete Seal fittings are manufactured from galvanized steelmeeting spec ASTM A-653 (Lockforming quality). They featurea double legged EPDM gasket which creates a virtually airtightconnection when slipped into spiral pipe. The gasketis mechanically attached to the fitting with a 180degree hemmed edge. This hem gives added rigidity to thefittings, ensures that the gasket will never slip out of place andmakes 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” DiameterThe E-Z flange with barrel clamp can be factory installedor shipped loose for field installation. A set consists of twoE-Z flanges and one barrel clamp. For field installation theinstaller attaches the E-Z flange to the pipe and fittings. Nextthe installer applies the gasket to one flange, mates the twoflanges together and attaches the barrel clamp. Sheet MetalConnectors can also install E-Z flanges. Flanges are spotwelded and internally sealed on all ends of the spiral pipe andfittings.E-Z Flange Jr. with Barrel Clamp 6” to 24” DiameterThe E-Z flange jr. is a 5/8” flange turned out 90 on each endof the spiral pipe and fittings. The installer applies a gasket onone flange, mates the two flanges together, and attaches thebarrel clamp. For field cuts a 5/8” flanged sleeve is available.Trim the spiral pipe to the measured length and attach thesleeve.Standard Spiral Pipe ConnectorPipe to Pipe connections are made by using a fitting sizecoupling that slips inside the mating pipe sections. A stopbead runs around the middle of the coupling to center thecoupling in the connection. Secure the connection byinstalling sheet metal screws through the outer shell of theduct, 1/2 inch from the stop bead.Companion Angle Rings Pressed and RolledCompanion angle rings are for end connections whenever a smoothinterior surface or intermediate stiffening is required. Rings aremanufactured from mild steel. Companion angle rings can befactory installed or shipped loose. Companion angle rings can beattached by solid weld, tack weld, or van stone connection.See companion angle ring size chart on page 20.

All pressed fittings are manufacturedfrom extra deep drawing steel (EDDS) in accordance with ASTM-A653. Pressed fittings are precision drawn, tolerances must bewithin or - .002 thickness to assure a quality product at all times. All pressed fittings are made of 24 Ga. or 22 Ga. Galvanizedmaterial with a G60 or better coating thickness and are chemically treated to retard white rust.Standing Seam Elbows & AnglesStanding Seam Elbows and AnglesStanding Seam fittings work well for medium pressure applicationsand offer an alternative to welded elbows and angles. These areavailable from 8” through 60” diameters and fabricated as heavy as16 gauge.
