Walraven pipe clamp 2S with lining set M8/M10 size 217–225 mm (33245225) pack of 10

Walraven pipe clamp 2S with lining set M8/M10 size 217–225 mm (pack of 10) is a lined metal clamp designed to support circular pipes and conduits with an external diameter within the 217–225 mm range. Each set includes a resilient lining that cushions the pipe, reduces noise and vibration transfer, and protects the pipe surface from abrasion. The clamp is compatible with M8 and M10 threaded fasteners and is supplied in a quantity of ten, suitable for multiple attachment points or larger installations.

Advantages

The lined construction provides mechanical protection for the pipe outer surface and reduces point loading, extending the service life of both clamp and pipe. The lining also dampens vibration and lowers structure-borne noise. Compatibility with M8 and M10 fasteners offers installation flexibility with common threaded rods and bolts. Supplied as a pack of 10, the set supports consistent, repeatable installation and helps maintain layout uniformity across a project.

Suitable for

• Supporting plumbing pipes in commercial and residential buildings
• Fixing HVAC ducts and chilled-water or heating pipes where vibration damping is needed
• Securing mechanical and process piping in light industrial installations
• Applications requiring protection of coated or soft-surfaced pipes from metal-to-metal contact

When it may not be suitable

This clamp set is intended for pipes whose outside diameter falls within the 217–225 mm range; it is not suitable for significantly larger or smaller pipes. It is a general-purpose lined clamp and may not meet specific requirements for very high-temperature lines, aggressive chemical environments, or specialty seismic/hanger systems unless those conditions are confirmed compatible with the clamp material and lining.

Key specifications

• Clamping range: 217–225 mm outside diameter
• Fastener compatibility: M8 and M10 threaded rods/bolts
• Includes protective lining to reduce vibration and prevent abrasion
• Material: lined metal clamp (metal type as supplied by manufacturer)
• Quantity per pack: 10 clamps with linings

How to use

Select clamps matching the pipe outside diameter and required support spacing. Place the lining inside the clamp saddle and position the clamp around the pipe, ensuring the lining fully contacts the pipe surface. Align the clamp with the support structure, insert an appropriate M8 or M10 fastener through the clamp holes, and tighten to secure the pipe while avoiding over-tightening that could compress the lining excessively. Use recommended torque values for the chosen fastener and check alignment and support spacing after installation.

What to consider before purchase

• Confirm the pipe outside diameter falls within 217–225 mm.
• Verify compatibility of the lining material with pipe coating, temperature and media.
• Check whether M8 or M10 fasteners suit your existing hanger system and load requirements.
• Determine required quantity based on support spacing and design standards for the specific fluid or service.

Usage recommendations

For vibration-sensitive systems, place lined clamps at regular intervals and combine with additional vibration isolators if needed. Inspect linings periodically for wear and replace clamps showing significant degradation to maintain protection and support performance.
