Galvanized steel duct pipe SpiroFlex 150 mm, 1 m, ø150, model PR-N150R1OCKN05

SpiroFlex galvanized steel duct pipe with a nominal diameter of 150 mm and a 1 m length is intended for use in ventilation and HVAC systems where rigid round ductwork is required. The pipe is made from zinc-coated steel to provide corrosion resistance and mechanical stability, and it is designed to connect to standard round fittings and ducts for air supply, exhaust and transfer in residential and commercial installations.

Advantages

The galvanized steel construction offers durability and resistance to rust in typical indoor ventilation environments. A standard 150 mm diameter and one-metre length simplify planning and installation, enabling straightforward alignment with existing round duct components. The smooth internal surface supports efficient airflow and reduces pressure losses, while the rigid profile helps maintain duct shape and connection integrity under standard operating conditions.

Suitable for

• Supply air distribution in residential and commercial HVAC systems
• Exhaust and ventilation ducts for kitchens, bathrooms and utility rooms
• Connecting round fans, grilles and filters in mechanical ventilation
• Short branch runs or extensions where rigid, corrosion-resistant ducting is required

Key specifications

• Nominal diameter: 150 mm
• Length: 1 m
• Material: zinc-coated (galvanized) steel
• Shape: round rigid duct
• Surface finish: galvanized for corrosion resistance
• Typical applications: ventilation, air supply and exhaust

How to use

Measure and mark the required run within the ventilation layout and cut or select appropriate lengths to fit. Join the SpiroFlex pipe to compatible round duct components using clamps, screws, or approved couplings and seal joints with appropriate duct sealant or foil tape to prevent air leakage. Support the pipe at regular intervals using brackets or hangers to maintain alignment and prevent sagging. Ensure that connected equipment and fittings are rated for the duct size and airflow conditions in the system.

Usage recommendations

Store the galvanized ducting in a dry area prior to installation to avoid surface contamination. During installation, avoid sharp bends and compressions that could restrict airflow; follow local ventilation codes for support spacing and sealing methods. For applications involving corrosive or external environments, consider alternative materials or protective measures appropriate to those conditions.
