Regarding the regulations for insulation material specifications according to the Ministry of Land, Infrastructure, Transport and Tourism standard specifications
■Flame retardantFrom 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 materialFrom 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.

Covered refrigerant piping Ant nest corrosion and construction precautions
■What is ant nest corrosion?On rare occasions, ant nest-like corrosion may occur in the copper pipes of coated refrigerant piping. Ant nest corrosion is a unique type of corrosion in which minute corrosion holes occur on the surface of copper pipes and progress inside.The corrosion pattern resembles an ant nest, so it is called "ant nest corrosion." It is said. The general mechanism by which ant nest corrosion occurs is that various organic substances are hydrolyzed to generate carboxylic acids such as formic acid and acetic acid as a corrosive medium.

The possibility of the formation of corrosive media is thought to be due to the effects of the following chemical products.

・Formaldehyde contained in brazing flux, lubricating oil, processing oil, etc.
・Antioxidants, pesticides, cosmetics, etc. that contain alcohol-based solvents
- Acetic acid contained in edible vinegar and seasonings. It has also been pointed out that environmental factors such as acid rain and condensed water accelerate this corrosion.

■Construction precautions (measures to reduce the occurrence of ant nest-like corrosion)- 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.
