industrial insulation optimum pipe insulation thickness - OMC Engineering Construction Contracting

In insulation applications, it is necessary to determine the appropriate pipe insulation thickness.

The following table shows the optimum pipe insulation thicknesses. If the pipes are outdoors, insulation thickness of 10-20 mm shall be added.
