Here are a few of our takeaways:
- The main reason to use the Metraloop is to significantly decrease the anchor loads. This leads to less guiding requirements.
- The Metraloop can handle all types of movement, even from seismic events. This also includes thermal expansion, thermal traction, off-set and building settlement.
- Keith discusses details of different kinds of loops.
- Metraloop or U-shaped loop: This is the most standard loop. One big reason that may prevent use is the large B dimension, which can sometimes have trouble fitting.
- The V Loop: This is shaped like a “V”, which allows the B dimension to be shorter and the A dimension to be a little longer. Therefore, this can be used when the Metraloop won’t fit. Note: You can nest these, but not always. Follow this rule: If the center to center dimension of the pipe in the rack (A) times 0.3 is less than the distance between OD of the insulation (Gap B), the standard V-loops will not be able to nest. Custom V-loops will be required.
- The Dog Leg:This is shaped like a “L.” It is inline, which means you need to have a 90 in your line. This replaced the Corner Loop to reduce on space.
- Always allow the return fitting to move! If you do not, then you will not get the full benefits of the This can also lead to a failure.
