Goldenwool@ insulation rock wool board is 5 pins per board ( or 6 pins per m2 ), and a of 8 pins per board (or 10 pins per m2 ) on the underneath. The pins are either welded directly onto the surface of the object or are screwed into nuts. The pins cannot be fixed to the pipes, but must be welded onto the bars between the pipes. Observe the following when pinning the insulation:
With insulation thicknesses < 5" (120 mm), use 8GA (6AWG) pins with a diameter of 0. 162" (4 mm)
- With insulation thicknesses ranging from 5 1/2" to 10" (130 to 240 mm), use 6GA (4AWG) pins with a diameter of 0.2043" (5 mm).
- With insulation thicknesses 2 10" (240 mm) use 4GA (3AWG) pins with a diameter of 1/4" (6 mm).
- If the cladding rests directly on the insulation without a gap between the two, the pins must be 3/8" (10 mm) shorter than the insulation thickness.
- Fasten each insulation layer with clips.With wired mats, all the lengthwise and crosswise joints must be sewn or wired together, or joined
With six mat hooks per meter. If the insulation is assembled in multiple layers, the joints of the individual insulation layers must be staggered. The following illustrations show a number of typical methods of insulating vessels.
