Most rubber and plastic pipe insulation materials are used for pipeline insulation. Usually, the most common thing we use is the heat preservation of the copper pipes of the air conditioner, which can reduce the heat loss of the pipes and play a role in energy saving and emission reduction. But in addition, what are the applications of rubber and plastic pipes? Today, the editor will explain to you.
Generally, most of the pipes that need to be insulated are higher temperature or higher temperature pipes. The outer surface of the pipeline is wrapped with rubber and plastic insulation materials, and the main purpose is also to keep warm. The pipes with higher temperature mainly include exhaust flue, cold and hot water pipe, steam pipe and so on.
One is the pipeline that needs to ensure temperature. Steam pipes, hot water pipes (radiator system 75/50 degrees Celsius, boiler heating system generally requires heat preservation for outlet water temperature of 60/50). The temperature of the exhaust air duct and steam exhaust duct in the kitchen is very high, which may reach 150 degrees Celsius, and the temperature of the exhaust air duct reaches 70 or even 280 degrees.
The other is that the heating medium must guarantee certain conditions or parameters. Cooling water, chilled water supply and return water, hot water supply and return water, air-conditioning air supply pipe, processed air-conditioning fresh air pipe, and air-conditioning return air pipe need to be insulated. The exhaust pipe is temporarily unnecessary, because the exhaust air does not need to guarantee certain state parameters.
Then there are pipes that are outdoors to prevent freezing. When installing or laying in a place where there is a risk of freezing. For example, cooling water, hot and cold water outdoor parts, the temperature in winter is very low, there may be a risk of freezing, so insulation is required to prevent freezing. This one is also suitable for outdoor ducts (outdoor ducts are rare now).
In addition, the medium in the pipeline is lower than normal temperature, or even lower than the dew point temperature. These considerations reduce cold loss and prevent condensation on the surface of the pipeline, requiring insulation. Supplementary air duct, in winter, the outdoor temperature is very low, resulting in low surface temperature of the supplementary air duct. Once it reaches the room, it will cause high-temperature indoor air, which may cause condensation when it encounters a cold wall, so the supplementary air duct also needs to be done Insulation.
Therefore, the most common pipes in daily life that need to be insulated by rubber and plastic insulation pipe sleeves are mainly air-conditioning cold and hot water pipes, cooling water pipes, steam heating pipes, etc.
