RIIFO MLCP External Bending Spring

Fitted around the outside of the pipe before bending, this spring works in the opposite way to its internal counterpart, clamping over the pipe wall to support it from without rather than being inserted through the bore. It's particularly useful where access to the pipe end isn't practical, such as on longer lengths or sections where the spring needs to be positioned partway along the pipe rather than fed in from an open end.

The spring distributes the bending force evenly across its length, helping the pipe curve smoothly rather than kinking or flattening at a single point of pressure. Once the bend has been formed, the spring simply slides off the pipe, leaving the surface undamaged and ready for the next step in installation. As with any bend formed in multilayer pipe, the radius of the curve, measured from the pipe's central axis, should be no less than five times the pipe's outer diameter, keeping the bend within safe limits for the material.

Available across the 16 to 32mm size range, this spring is sized to match the corresponding pipe diameter, offering an alternative to the internal spring where external access is more practical than working through the pipe bore.

• External support during bending: Clamps around the pipe wall from the outside, useful where the pipe end isn't accessible for an internal spring.
• Even force distribution: Spreads the bending load along its length, helping prevent kinking or flattening at a single point.
• Slides off after use: Simply removes from the pipe once the bend is complete, leaving the surface undisturbed.
• Matched to pipe diameter: Available across the 16 to 32mm range, with each size suited to its corresponding pipe diameter.
