Our Products #4728862

Sheet Metal Connectors, Inc. spiral pipe is formed from a coil of prime 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 12 times that of longitudinal lockseam 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 E-Z Flange with Barrel Clamp, E-Z Flange Jr. with Barrel Clamp, Complete Seal System, Spiral Pipe Connector, or Companion Angle Rings.

The E-Z Flange Jr. Spiral Pipe System is assembled by applying a gasket to one flange, mating the two flanges together, and attaching the barrel clamp. The E-Z Flange Jr. Spiral Pipe System is sealed so tight that it out performs both ASHRAE and SMACNA Leakage Class 3 Testing. There is virtually no leakage at the transverse connections (test data available).

Meets SMACNA Rigidity Class A per the SMACNA Testing and Research Institute.
E-Z Flange Jr. sets are fabricated to fit inside the spiral pipe and fittings ranging from 6 to 24 diameter.
Manufactured from 22 gauge galvanized material meeting specifications ASTM A-653 (lock forming quality).
Also available in PVS, aluminum, and paint grip materials upon request.
E-Z Flange Jr. can be installed on site.
Ducts can be disassembled and reassembled
E-Z Flange Jr. is assembled using a barrel clamp system that locks together with two 38 carriage bolts, no screws are required.
E-Z Flange Jr. can be used on single wall, double wall.
Test data available.
Sold in sets only, a set consists of 2 flanges, and 1 barrel clamp.

All pressed fittings are manufactured from extra deep drawing steel (EDDS) in accordance with ASTM-A653. Pressed fittings are precision drawn, tolerances must be within + or .002 thickness to assure a quality product at all times. All pressed fittings are made of 24 Ga. or 22 Ga. Galvanized material with a G60 or better coating thickness and is chemically treated to retard white rust.

COMPLETE SEAL fittings are manufactured from galvanized steel meeting spec ASTM A-653 (Lockforming quality) for Spiral Pipe. 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 has been pressure tested and meets the requirements of SMACNA Leakage Class 3 for -10w.g. to +10w.g (test data available upon request). Complete Seal gasket has an operating temperature of -40 degrees to +250 degrees Fahrenheit. The smoke and flame spread is 00 in compliance with ASTM E-84-91A.

COMPLETE SEAL fittings are designed to slip snugly into your spiral pipe. Simply insert the fitting to the spiral stop bead and secure with self tapping sheet metal screws. Screws must be placed within one inch of the spiral stop bead and at uniform intervals not to exceed 15 along the circumference. A minimum of three screws must be used on all diameters 14 or less.

All pressed fittings are manufactured from extra deep drawing steel (EDDS) in accordance with ASTM-A653. Pressed fittings are precision drawn, tolerances must be within + or .002 thickness to assure a quality product at all times. All pressed fittings are made of 24 Ga. or 22 Ga. Galvanized material with a G60 or better coating thickness and is chemically treated to retard white rust.
