Clamp ALPAR Obejma O-1 FI 155-190 (model O1) for pipe mounting, adjustable 155–190 mm

The ALPAR Obejma O-1 FI 155-190 (model O1) is an adjustable metal pipe clamp designed to secure round pipes and ducts with diameters from 155 mm to 190 mm. It provides mechanical fixation for installations in plumbing, ventilation, HVAC and industrial settings where an adaptable, sturdy mounting is required. The clamp is constructed for straightforward adjustment and tightening to match the specified pipe range and maintain alignment during installation and maintenance.

Advantages

The clamp offers a simple adjustable range covering 155–190 mm, enabling one product to fit multiple pipe sizes. Its metal construction delivers stable mechanical support and resistance to deformation under typical installation loads. The design facilitates quick on-site size adjustment and reliable fixation without complex tools.

Suitable for

• Securing round ventilation ducts and exhaust pipes within 155–190 mm diameter range
• Mounting plumbing pipes and conduits in residential and commercial HVAC systems
• Temporary or permanent fixation during installation and maintenance operations
• Industrial applications requiring an adjustable clamp for medium-diameter cylindrical components

When it may not be suitable

This adjustable clamp is intended for round pipes and ducts within the specified diameter range; it is not suitable for pipes outside 155–190 mm or for non-cylindrical profiles. For applications requiring vibration isolation, electrical insulation, or corrosion resistance in aggressive environments, additional materials or specialized clamps may be necessary.

Key specifications

• Adjustable diameter range: 155–190 mm
• Designed for round pipes and ducts
• Material: metal construction for mechanical support
• Typical use: plumbing, ventilation, HVAC and industrial mounting

How to use

Select the clamp and position it around the pipe so the band fully encircles the pipe surface. Adjust the clamp diameter within the 155–190 mm range by tightening or loosening the adjustment mechanism until the clamp sits snugly against the pipe. Secure the clamp to the mounting surface or support structure using appropriate fasteners and torque for the installation conditions. Confirm alignment and retighten as needed after initial system operation and during maintenance checks.

What to consider before purchase

• Verify the external diameter of the pipe or duct falls within 155–190 mm
• Confirm that a metal clamp is acceptable for the installation environment (corrosion, chemical exposure)
• Ensure compatible mounting points and fasteners are available for fixed installation

Usage recommendations

For secure installation, use fasteners and anchors rated for the support structure and load. If vibration damping or electrical isolation is required, add appropriate inserts or pads between the clamp and the pipe. Periodically inspect clamps for tightness and corrosion during routine maintenance.
