SpiroFlex stainless steel smooth pipe 110 mm, 0.5 m

SpiroFlex stainless steel smooth pipe 110 mm, 0.5 m is a straight, corrosion-resistant duct section designed for ventilation, flue and general HVAC ductwork where a smooth internal surface and reliable stainless construction are required. The tube’s 110 mm nominal diameter and 0.5 m length make it suitable as a connecting section or repair piece in both residential and commercial installations. Its smooth internal bore reduces air resistance and helps maintain airflow efficiency in mechanical ventilation and exhaust systems.

Advantages

The stainless steel construction provides durability and resistance to corrosion, making the pipe suitable for environments with moisture or condensate. The smooth internal surface minimises turbulence and pressure loss compared with corrugated alternatives, supporting quieter operation and improved airflow. The standard 110 mm diameter and compact 0.5 m length allow easy handling, cutting and fitting in tight spaces, while the smooth external surface simplifies sealing and connection with clamps or couplers.

Suitable for

• Mechanical ventilation ducts in apartments and houses
• Exhaust and flue connections for range hoods or small appliances
• HVAC repair and extension work in commercial premises
• Inline sections where corrosion resistance is required

Key specifications

• Nominal diameter: 110 mm
• Length: 0.5 m
• Material: stainless steel (smooth bore)
• Surface: smooth internal and external finish for reduced airflow resistance
• Application: ventilation, flue, ductwork

How to use

Measure and prepare the duct ends to ensure a flush fit with adjacent pipes or fittings. Slide the SpiroFlex stainless steel smooth pipe into position and secure with appropriate clamps, couplers or sealed connectors compatible with 110 mm ducts. Where required, apply a suitable high-temperature or HVAC-grade sealant to joints to ensure airtight connections. Cut the pipe to length using metal cutting tools and deburr edges before installation to maintain a smooth flow path.

Usage recommendations

For best results, use this smooth stainless section in straight runs or between rigid fittings to retain the low-resistance airflow benefits. Avoid excessive bending; if directional change is needed, use purpose-made elbows or adjustable connectors. Regularly inspect joints and supports for corrosion or looseness in environments with high moisture or aggressive condensate.
