The length of the Huangming Solar 18tt18 tube is 1.8 meters, the outer diameter is 5.8 cm, and the inner diameter is 3.7 cm. According to the petition, relevant information shows: The Huangming Solar 18tt18 tube is a thermal superconductor and is the most efficient heat transfer element currently available to man. The starting temperature of the heat pipe is low and the heat exchange speed is fast in winter. Therefore, the length of the Huangming Solar 18tt18 tube is 1.8 meters, with an outer diameter of 5.8cm and an inner diameter of 3.7cm.
The solar hot water outlet pipe 16 is not thin and is of standard size. The solar hot water outlet pipe 16 is not thin and is of standard size. There are two types of upper and lower water pipes for solar water heaters: 20 and 16, which are 4-point and 6-point. The water inlet pipe of the solar water heater generally measures16mm diameter. That is, 4 separate tubes are enough for domestic use, but higher specifications are required for commercial use. The most commonly used pipe material is 304 stainless steel corrugated pipe.
