Sem stendur, þegar flestar fjölskyldur setja gólfhitarör, eru þær nánast óaðskiljanlegar frá þessum 4 flokkum, sem eru 16, 20, 25 og 32 í sömu röð. Talan sem hér er nefnd vísar almennt til ytra þvermáls, í millimetrum, þannig að því stærri sem talan er, því þykkari er hún. Þannig að þú getur séð þykkustu jarðhitapípuna, sem er 32 mm í almennum forskriftum okkar.
When talking about the common specifications of floor heating pipes, another concept needs to be implanted, that is, the thickness of the inner wall. Because the real anti-pressure is not determined by the thickness, but by the thickness of the inner wall. Therefore, if you are more concerned about anti-pressure, you also need to pay attention to the wall thickness when purchasing geothermal pipes.
The thicker the floor heating pipe, the higher the installation height and the more sediment filling cost. Therefore, in general families, 20 and 25 gauge floor heating pipes are basically used.Generally speaking, 20 floor heating pipe will be used for coil installation, and 25 floor heating pipe will be used for main pipe installation. This is just like the PPR pipe. The main pipe increases the water flow during the water delivery process, which can make the water in the branch pipe flow back faster and make the heating and insulation more stable.
