Loop should hang straight down and be free to flex. Guides are required to direct movement axially.
Support must be provided to prevent the loop from leaning. Pipe hanger rod should be loose enough to allow the 180ƒ return to move up or down 1/4" as the loop flexes. Guides are required to direct movement of pipe axially.
This installation is recommended for steam*. Support must be provided to prevent the loop from drooping or torquing pipe. Support must allow the 180ƒ return, to move horizontally back and forth 1/4", as the loop flexes. Guides are required to direct movement of pipe axially.
*Any other orientation may cause condensate to collect.
Loop must be supported to allow the 180ƒ return to move horizontally back and forth 1/4" as the loop flexes. Guides are required to direct movement of pipe axially.
For tight pipe runs, any size or number of loops can be designed to nest inside of one another. To order, specify sequence of pipe diameters and corresponding distances between pipe centerlines.
One Metraloop simultaneously absorbs the thermal expansion of two pipe runs. Space-saving inside corner Metraloop eliminates the need for an anchor at the corner. Guides are required to direct movement of pipe axially. Support must be provided to prevent Metraloop from drooping or torquing pipe and must allow for sufficient movement.
The Metraloop expansion loop can be manufactured in a variety of configurations. For technical assistance, contact your nearest Metraflex representative, or contact Metraflex directly.

† When ordering a Metraloop with double-braid, please include the letter "D" at the end of the Model #. Example: MLWNSF30200D
* Spring Force: These values reflect the total force required to move the Metraloop its full rated movement for 150 P.S.I. at 70 F.
For higher pressures please contact Metraflex.
** Loops are available in half sections for ease of handling and shipping. If this option is selected add half inch to the "end to end" dimension.
