Support Clamps for Aquatechnik Piping: Riser Clamps and Bifix Clamps

Proper pipe support is critical in Aquatechnik PPR systems to ensure longevity, alignment, and safety. This article explains the use of riser clamps and bifix clamps, including when and where they should be used for vertical and horizontal pipe runs.

🧱 What Is a Riser Clamp?

A riser clamp is a load-bearing clamp used on vertical pipe runs (risers) to support the weight of the pipe and its contents. These clamps typically wrap around the pipe and rest on the building’s structure (e.g., slab or steel beam), transferring the vertical load safely.

✔️ Use at:

- Base of every floor to support the vertical pipe weight.

🧰 What Is a Bifix Clamp?

A bifix clamp is a non-load-bearing pipe clamp that secures the pipe in place while allowing minor movement and vibration damping. It includes a rubber insert to protect Aquatechnik’s plastic piping and prevent wear from movement or contact with metal.

✔️ Use on:

- Vertical runs (risers) to reduce deflection or flexing between riser clamps.

- Horizontal runs to keep alignment and prevent sagging.

 

📍 Vertical Riser Clamp Placement (Per Floor)

Pipe Size	Clamp Type	Placement Guidelines
All sizes	Riser Clamp	1 per floor, located at base of each floor (where floor slab or beam can bear weight)
1" and smaller	Bifix Clamp	1 per floor at midway point; if floor height >10 ft, space every ~10 ft
Over 1"	Optional Bifix	May be used as needed for alignment or added stability

📏 Horizontal Clamp Spacing Guidelines

Pipe Size (PPR)	Max Horizontal Spacing
1"	Every 3 feet
1½"	Every 5 feet
2" to 4"	Every 8 feet
6" to 12"	Every 10 feet

🛠️ Key Notes

- Never use metal-only clamps directly on Aquatechnik piping. Use bifix or equivalent with rubber inserts to prevent pipe damage.

- Ensure structural attachment of riser clamps. They must rest on solid structural elements.

- Horizontal clamps should be mounted to unistrut, wall brackets, or trapeze hangers depending on the pipe route.
