給湯用輸送管を提供するものである。The above-mentioned stainless steel bellows pipe with a synthetic resin coating layer is excellent for gas pipes. However, for example, when it is used for pipes for transporting clean water, moisture in the air causes dew condensation. There is a problem that dew is generated on the surface of the pipe, or when it is used for hot water piping, heat is exchanged with the outside air temperature around the piping to lower the temperature of hot water for transportation. Therefore, it is necessary to wrap a heat insulating material on the outer peripheral surface of the pipe,
It was rarely used except for some limited uses.
Therefore, the present invention increases the heat insulating property with respect to the ambient temperature around the pipe,
(EN) Provided is a transport pipe for hot and cold water supply, which makes it easy to construct a pipe without dew on the surface of the pipe.
