Heavy-duty sprinkler pipe clamp Niczuk 1/2 (20–22) for fire sprinkler installations

Heavy-duty Niczuk pipe clamp designed for fire sprinkler installations; this model fits 1/2-inch sprinkler piping with outer diameters of 20–22 mm and provides a robust support point for fixed sprinkler lines. The clamp secures piping to structural elements, reduces vibration and lateral movement, and helps maintain correct alignment of the sprinkler network to meet installation standards and operational safety requirements.

Advantages

The clamp is manufactured from durable materials formulated for mechanical strength and long service life in building installations. Its profile provides a tight, stable grip on 20–22 mm sprinkler pipes while allowing straightforward mounting to beams, channels or concrete using standard fasteners. By minimising pipe movement and absorbing minor shocks, the clamp supports system reliability and reduces stress on joints and fittings.

Suitable for

• Commercial and residential wet and dry fire sprinkler systems
• Securing 1/2-inch sprinkler lines with outer diameter 20–22 mm
• Installation on steel beams, threaded rod with support brackets, cable trays and concrete surfaces
• Areas requiring vibration control and precise pipe positioning

Key specifications

• Compatible pipe outer diameter: 20–22 mm
• Intended pipe nominal size: 1/2 inch sprinkler piping
• Application: fixed mounting for fire sprinkler installations
• Function: mechanical support, vibration reduction and alignment of sprinkler lines
• Mounting: suitable for attachment to structural elements using appropriate fasteners

How to use

Position the clamp around the sprinkler pipe so the pipe rests securely in the saddle. Align the clamp with the chosen structural attachment point and fix it using suitable fasteners (bolts, screws or threaded rod assemblies) compatible with the installation substrate. Ensure the clamp holds the pipe without over-tightening, allowing for thermal expansion where necessary and keeping the line properly aligned to adjacent fittings and hangers. Check tightness and alignment after initial tightening and again after system testing.

Usage recommendations

Use corrosion-resistant fasteners in corrosive environments, follow applicable fire protection installation standards, and space clamps according to local codes and engineering specifications to maintain system integrity and performance.
