Integrity Products Cryogenics Plugs are specially designed for cold service applications. These ports are manufactured as a simple 3-part assembly for cold service insulated piping systems. The 1st component consists of the Plug itself with the addition of an aluminum ring with inserts for banding applications. The 2nd component is an insulation insert made from a closed cell foam material with a PTFE strap that is mechanically mounted into place, and the 3rd component is a PTFE sleeve that can be cut to insulation thickness, which protects against air infiltration under the insulation. This also serves as a barrier for the foam pillow creating a suction type fit, a thermal brake designed at the base of the sleeve to curve around the outer diameter of the pipe.
The design and materials of the Cryogenic Plugs are uniquely formulated for fluctuating and sub-zero temperatures. Together, all of these factors come together to create a vapor/moisture barrier and reduces the risk of frost/ice build-up forming on the insulated system, making these plugs essential for allowing access for NDT on insulated pipes, vessels, tanks and equipment.
