Space Requirements of Insulation

The space requirements of the insulation must be taken into account when the installation is being designed and planned. Therefore, the insulation thicknesses should be determined in the early planning stages and the distances between the individual objects should be taken into account in the piping isometrics. To guarantee systematic installation of the insulation materials and the cladding without increased expense, observe the minimum distances between the objects as specified in the following illustrations.

Minimum distances between vessels and columns; dimensions in inches (mm)

Minimum distances between insulated pipes; dimensions in inches (mm)

Minimum distances within range of pipe flanges; dimensions in inches (mm)

• a = distance flange to normal insulation
• a ≥ 2in (50 mm)
• x = bolt length + 1.2in (30 mm)
• s = insulation thickness
