Pre-curled Isogenopak® jacketing film is supplied in rolls of 35 m in length with 1000 mm as the most common width. The Isogenopak® system is completed by a large variety of pre-molded bends, T-sections, caps, and cuffs.
T-section
First the insulator must be attached to the pipe without gaps. When using mineral wool sections, loose fill wool can be used to cover the bends and other shapes. The insulator has to be affixed to the pipe consistently.
Cutting of Isogenopak® with a guide rail.
To attach the Isogenopak® jacketing we advise to start with the molded pieces, e.g. bends (1) and T-sections (2).
Fitting of Isogenopak® to a straight section
For straight sections, Isogenopak® is cut from the roll according to the circumference to be clad. Allow an extra 20-30 mm for overlapping. A guide rail for the cutter (3) has proven its worth.
Closing longitudinal seams with plastic push-in rivets
Because of the pre-curling, Isogenopak® clings around the insulated pipe (4) almost by itself. Just a little additional adjustment is required. The circumferential seams should overlap by about 20-30 mm as well.
Longitudinal seam closed with special solvent-based adhesive
Isogenopak® is fixed along the longitudinal seams either by using plastic push-in rivets in distances of about 150 mm (5) or special solvent-based adhesive continuously along the seams (6).
