Application

Designed for supply and return air systems, the Series 1 round pipe is commonly used for trunk and branch duct runs. Its slip-fit ends allow for quick installation with elbows, reducers, and other fittings, maintaining airflow efficiency with minimal leakage when properly sealed.

Installation Considerations

Contractors should follow SMACNA-approved installation practices for low- and medium-pressure duct systems. All joints must be mechanically fastened with sheet metal screws or draw bands, then sealed using UL-listed foil tape or duct mastic to ensure code compliance and long-term efficiency.

Key Features

• Durable Construction: Galvanized steel with corrosion protection for extended service life.
• System Compatibility: Interfaces with standard round duct fittings and HVAC components.
• Precision Fit: Slip-fit ends simplify alignment and joint connection in the field.
• Code Compliance: Fabricated to ASTM and SMACNA standards for round duct applications.

The Lukjan Round Heat Pipe provides HVAC contractors with a dependable, specification-grade solution for ducted air systems. Its robust construction and standards compliance make it suitable for both new installations and retrofit projects requiring consistent airflow performance.
