The outer diameter of plumbing 32 steel pipe is 42.4mm, the wall thickness is about 3.25 mm, and the galvanized steel pipe is 1.32 inch. The outer diameter is 42.4mm, the wall thickness is 3.5mm, the minimum wall thickness is 3.06mm, the rice weight is 3.56kg, and the root weight is 3 1.56kg. The hot-dip galvanized pipe is an alloy layer formed by the reaction between molten metal and iron matrix.

Water heating is a kind of floor radiant heating, and it is also the most popular heating method, which has quite advantages compared with electric heating. Water heating is through the ground coil, circulating hot water in the pipeline, through the heat medium in the radiation layer of the floor, using the law of heat storage and upward radiation on the ground itself, and conducting from bottom to top to achieve the purpose of heating.

Because the indoor temperature gradient from the soles of the feet to the head gradually decreases, it gives people the comfort of warming their feet and cooling their heads. Radiant floor heating conforms to the fitness theory of "warm feet and cool roof" in traditional Chinese medicine. It is the most comfortable way of heating and a symbol of modern life quality.

The radiator heats up faster. When heating is started in the circulating system, the cement layer above the hot water pipe needs to be heated first, then the floor, and then the air is heated by the floor. It takes a long time from opening to reaching the expected temperature. The radiator terminal dissipates heat without heating the cement layer and floor, and the indoor temperature rises rapidly for the first time.
