Regarding the regulations for insulation material specifications according to the Ministry of Land, Infrastructure, Transport and Tourism standard specifications
■Flame retardant
From April 1, 2013, specifications for flame-retardant insulation materials have been stipulated. All of our insulation materials for coated refrigerant piping are flame retardant.
■Thickness of insulation material
From April 1, 2020, regulations have been changed to require the thickness of insulation material for liquid pipes to be 10 mm or more regardless of pipe size. Until now, if the nominal diameter of the liquid pipe was φ9.52 or less, it was possible to use insulation material with a thickness of 8 mm or more, but from now on, the thickness of the insulation material for liquid pipes will need to be 10 mm or more regardless of the pipe size.
■Coated refrigerant piping Ant nest corrosion and precautions during construction
- Ant nest corrosion occurs more frequently in environments where oxygen, moisture, and corrosive media exist. Please pay attention to the following points when constructing piping.
- Completely seal the gap between the insulation material and the copper pipe with caulking to prevent condensation or rainwater from entering. Please be especially careful about the downward piping of the outdoor unit. When brazing copper pipes, do not use antioxidants containing alcohol-based solvents.
