OVERVIEW: ML Loop Flexible pipe loops from Flexicraft are an important alternative in adding flexibility to a piping system. Compared to hard pipe loops, they take up much less space, require fewer supports, and are more economical. Compared to traditional metal expansion joints, they have outstanding flexibility and no pressure thrust loads that can add large stresses to anchors and require more guiding. Also see our V-Loop variation.
Movement of 1-1/2" or 4" in all three directions are standard, but any movements can be accomodated with factory assistance. Flanged, weld, grooved, or copper sweat ends are avaialble.
Single loops are available, as are nested loops for pipelines that run parallel. The loops are also available with liners, CSA/AGA approved, and with any weldable materials.
Any application where compensation for pipe movement is required, from the unpredictable seismic to the calculated thermal expansion, our flexible loops can meet your requirements.
Pipe Guides are also available for use with the loops, although fewer guides are required than standard metal expansin joints.
Contact factory for use in steam systems.
- Independent pair of flexible legs allows considerable movement in any direction
- Eliminates thrust load an piping anchors with the use of the stainless steel braiding
- Compact compared to hard pipe loops
- Available in stock or custom designs
- Accommodating thermal growth and minimizing anchor loads from traditional expansion joints
- Accommodating thermal growth and minimizing space needed from hard pipe loops
- Where larger axial and lateral movements and low thrust loads and spring rates may be wanted
TEMPERATURE: to 850°F for CS Ends, Note Pressure Derating
