Southwark Metal SL24-30GA_12IN Round Galvanized Pipe 30GA 12in

Product Description

The SOUTHWARK METAL SL24-30GA_12IN is a round galvanized sheet metal pipe section used in low-pressure HVAC duct distribution systems. Fabricated from hot-dip galvanized steel at 30 gauge, it measures 12 inches in diameter and 24 inches in length. The snap-lock seam construction allows fast field assembly without requiring additional fasteners at the longitudinal joint. HVAC sheet metal installers and duct fabricators use this pipe for straight trunk and branch runs in both residential and light commercial forced-air systems. It meets ACCA and SMACNA applicable standards, making it appropriate for code-compliant duct installations.

This pipe section fits into standard round duct systems where a 12-inch diameter, 24-inch straight run is needed. It is commonly used in supply and return air distribution, connecting to fittings, elbows, tees, and transitions that match the 12-inch round profile. The 30-gauge galvanized construction is suited for low-velocity, low-pressure duct applications typical in residential new construction, renovation, and light commercial HVAC work.

Key Features

• Hot-dip galvanized steel construction resists corrosion in typical duct environments
• 30-gauge material thickness meets SMACNA and ACCA standards for low-pressure round duct
• Snap-lock seam for fast, tool-minimal longitudinal joint closure during installation
• 12-inch diameter by 24-inch length provides a standard straight section for duct layout planning
• Compatible with standard round duct fittings, collars, and connectors at the 12-inch size

Compatibility

Designed as an OEM-style round duct pipe section for use in ACCA- and SMACNA-compliant low-pressure HVAC duct distribution systems requiring 12-inch round pipe.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers following SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and confirm zero airflow before connecting or modifying duct sections. Snap-lock seams should be fully seated before securing joints with sheet metal screws and approved duct sealant per local code requirements. Do not use this pipe section in high-pressure duct systems or applications outside its rated gauge and diameter.
