Basic Construction: Closures
|
|
Once the removable-reusable insulation piece has been fitted around the piece of equipment to be insulated, some type of closure is required to hold it in place. There are several types of closures, including the following.
Fire Retardant Industrial-grade Velcro on a Strap
The strap is threaded through a stainless steel D-Ring buckle, doubled back on itself and pressed closed. This makes a good and strong durable closure and lends itself well to rapid removal of the removable-reusable insulation for maintenance.
Lacing Anchors
These are generally used for extremely high temperatures. The closure ligament used for lacing the removable-reusable insulation closed through the lacing anchors is generally 18-gauge stainless steel wire. This remains strong and serviceable in elevated temperature applications.
Draw Chords
The analogy here would be comparable to tying your shoelaces. Stainless steel grommets are installed along the closure edge of the removable-reusable insulation. Light "ropes" are threaded through the grommets and laced up to provide a good closure. The ropes can be made from quite ordinary or quite sophisticated materials. These can include: glass fiber, Nylon, Kevlar, or Fluorocarbon impregnated as may suit the application and operating environment.
