用于通风空调管道和各类管道的保温材料主要有：聚氨酯泡沫保温、橡塑保温、酚醛泡沫保温、铁管等。本文就上述材料的特点、适用范围、施工要点等作一介绍，供大家参考。
For ventilation and air conditioning pipes and all kinds of pipe insulation materials are: Polyurethane Foam insulation, high-grade rubber insulation, phenolic foam insulation, iron pipes. In this paper, the characteristics of the above-mentioned materials, scope of application, construction points and so on are introduced for your reference.
本材料用于直埋管段保温。它与传统的沟槽管道相比，山东通风管道具有保温、防腐、绝缘、寿命长、施工安装简单、占地面积小、工程造价低等一系列优点，现已广泛应用于集中供热、输油、化工、制冷及高寒地区供水等领域，本文不作详细介绍。
This material is used for directly buried pipe insulation. Compared with the traditional trench pipe, the Shandong ventilation pipe has a series of advantages, such as heat preservation, anticorrosion, insulation, long service life, simple construction and installation, small floor area, low project cost, etc. , it has been widely used in the fields of central heating, oil transportation, chemical industry, refrigeration and water supply in high and cold area.
它是一种更理想的绝热材料，其绝热材料具有良好的绝热效果，用于同一条管道所使用的保温厚度薄、用量少；同时为整体成型保温材料，工艺较为简单、快捷；此外，橡塑属于绿色、、保温材料，对健康无害。这种材料因其突出的优点，在空调制冷系统的载冷剂管道、冷凝水管的保温中得到了越来越广泛的应用。
It is a more ideal thermal insulation material, its thermal insulation material has a good thermal insulation effect, used for the same pipe insulation thickness, the amount of less; at the same time, as a whole forming thermal insulation material, the process is simpler and faster; in addition, advanced rubber and plastic belong to green, environmental protection, thermal insulation materials, harmless to health. Because of its outstanding advantages, this kind of material has been used more and more widely in the heat preservation of refrigerant pipes and condensing water pipes in air conditioning and refrigeration systems.
采用丁晴橡胶(NBR)和 PVC (PVC)工艺发泡而成的橡塑整体成型无机类隔热材料。可在零下5 O℃~l20℃的介质中使用，其闭孔结构具有更好的绝热性能和较低的防潮吸水能力。主要的优点是橡塑保温材料具有以下优点：绝热效果好，防露效果显著，宜作为保温管道的更外层；阻燃防烟、可靠；外观均匀、高档美观、安装方便、施工快捷。
NBR AND PVC (PVC) foamed from the overall molding of advanced rubber-plastic inorganic insulation materials. The utility model can be used in the medium of-5o °C ~ L20 °C, and the closed-hole structure has better thermal insulation performance and lower moistureproof and water absorption capacity. The main advantages are the following: high-grade rubber insulation material has the following advantages: good insulation effect, anti-dew effect, appropriate as the insulation pipe outermost layer, flame-retardant smoke, safe and reliable; Uniform appearance, high-grade beautiful, easy installation, construction fast.
山东通风管道加工主要应用于民用建筑的空调、家用空调制冷系统制冷剂管道保温、冷凝水管道保温、汽车空调管道保温、热水管道保温、各种工业大口径管道保温以及船舶、航空、城市热网等的隔热隔冷系统。
Shandong ventilation pipe processing is mainly used in civil buildings, home air conditioning refrigeration system refrigerant pipe insulation, condensate pipe insulation, automobile air conditioning pipe insulation, hot water pipe insulation, various industrial large caliber pipe insulation, as well as ships, aviation, urban heat insulation and cold insulation system.
管子保温前应先做管道压力测试，试压合格后应对试压和保温工序进行交接，以防未进行试压的水管保温，避免工作冲突。
Pipe insulation should be done before the pipeline pressure test, pressure test and insulation procedures should be transferred after passing the test, in order to prevent the water pipe insulation without pressure test, to avoid working conflict.
由于系统内介质温度与环境温度差较大，
山东通风管道的加工选用厚度越大，所选择的冷却系统所在环境相对湿度越大，选择厚度越大；冷媒介质管径小150 mm时，管径越大，选择厚度越大。
Due to the large temperature difference between the medium and the environment in the system, the larger the thickness of the ventilation pipe in Shandong Province is, the larger the relative humidity of the cooling system is, and the larger the thickness is, the greater the selection thickness,.
