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溫。它與傳統(tǒng)的溝槽管道相比，山東通風(fēng)管道具有保溫、防腐、絕緣、壽命長、施工安裝簡單、占地面積小、工程造價(jià)低等一系列優(yōu)點(diǎn)，現(xiàn)已廣泛應(yīng)用于集中供熱、輸油、化工、制冷及高寒地區(qū)供水等領(lǐng)域，本文不作詳細(xì)介紹。
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.
它是一種更理想的絕熱材料，其絕熱材料具有良好的絕熱效果，用于同一條管道所使用的保溫厚度薄、用量少；同時(shí)為整體成型保溫材料，工藝較為簡單、快捷；此外，橡塑屬于綠色、、保溫材料，對健康無害。這種材料因其突出的優(yōu)點(diǎn)，在空調(diào)制冷系統(tǒng)的載冷劑管道、冷凝水管的保溫中得到了越來越廣泛的應(yīng)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.
采用丁晴橡膠(NBR)和 PVC (PVC)工藝發(fā)泡而成的橡塑整體成型無機(jī)類隔熱材料。可在零下5 O℃~l20℃的介質(zhì)中使用，其閉孔結(jié)構(gòu)具有更好的絕熱性能和較低的防潮吸水能力。主要的優(yōu)點(diǎn)是橡塑保溫材料具有以下優(yōu)點(diǎn)：絕熱效果好，防露效果顯著，宜作為保溫管道的更外層；阻燃防煙、可靠；外觀均勻、高檔美觀、安裝方便、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.
山東通風(fēng)管道加工主要應(yīng)用于民用建筑的空調(diào)、家用空調(diào)制冷系統(tǒng)制冷劑管道保溫、冷凝水管道保溫、汽車空調(diào)管道保溫、熱水管道保溫、各種工業(yè)大口徑管道保溫以及船舶、航空、城市熱網(wǎng)等的隔熱隔冷系統(tǒng)。
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.
管子保溫前應(yīng)先做管道壓力測試，試壓合格后應(yīng)對試壓和保溫工序進(jìn)行交接，以防未進(jìn)行試壓的水管保溫，避免工作沖突。
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.
由于系統(tǒng)內(nèi)介質(zhì)溫度與環(huán)境溫度差較大，
山東通風(fēng)管道的加工選用厚度越大，所選擇的冷卻系統(tǒng)所在環(huán)境相對濕度越大，選擇厚度越大；冷媒介質(zhì)管徑小150 mm時(shí)，管徑越大，選擇厚度越大。
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,.
