来源:http://www.sdhpgy.com 日期:2019-06-21 发布人:admin
钢套钢直埋蒸汽保温管(钢套钢直埋蒸汽保温管)是由保送介质的钢管、防腐外套钢管以及钢管与外套,钢管之间填充的超细玻璃棉组合而成。
Steel-jacketed steel direct-buried steam insulation pipe (steel-jacketed steel direct-buried steam insulation pipe) is composed of steel pipe, anti-corrosion coated steel pipe and superfine glass wool filled between steel pipe and coat.
钢套钢直埋蒸汽保温管保温构造根据滑动方式不同分为:内滑动式与外滑动式
According to different sliding modes, the thermal insulation structure of steel-jacketed direct-buried steam insulation pipe can be divided into internal sliding type and external sliding type.
应用:
Application:
钢套钢直埋蒸汽保温管普遍用于液体、气体的保送管网, 化工管道保温工程石油、化工、集中供热热网、中央空调通风管道、市政工程等。
Steel-jacketed steel direct-buried steam insulation pipe is widely used in liquid and gas pipeline network, chemical pipeline insulation engineering petroleum, chemical industry, central heating network, central air-conditioning ventilation pipeline, municipal engineering, etc.
用钢套钢直埋蒸汽保温管的保温、滑动光滑和暴露管端的防水问题。保温管不只具有传统地沟和架空敷设管道难以比较的先进技术、适用性能,而且还具有显著的社会效益和经济效益,也是供热节能的有力措施。
Insulation, smooth sliding and waterproofing problems of directly buried steam insulation pipe with steel sleeve are exposed. Thermal insulation pipe not only has advanced technology and applicability which is difficult to compare with traditional trench and overhead pipeline laying, but also has remarkable social and economic benefits. It is also a powerful measure of heating energy saving.

外滑动构造技术特性:
Technical characteristics of outer sliding structure:
1、外滑动构造由于保温层与外护管之间有一层空气层,管道在运输及施工过程中浸的水可在逐渐暖管过程中排出,因此比拟合适于雨量充分、水位高的地域。但关于氯离子、硫离子等含量比拟高的土壤(特别在沿海地域),对外钢管的防腐需增强。
1. Because there is an air layer between the insulation layer and the outer protective pipe, the water immersed in the pipeline during transportation and construction can be discharged during the gradual heating pipe process, so the fitting method is more suitable for areas with sufficient rainfall and high water level. However, for soils with relatively high contents of chloride and sulfur ions (especially in coastal areas), the corrosion prevention of external steel pipes needs to be enhanced.
2、外滑动构造是基于“钢地沟”的思想设计而成,可充沛应用弯头停止自然补偿,降低了本钱,同时减小了固定墩推力。
2. The outer sliding structure is designed based on the idea of "steel trench". It can make full use of elbow to stop natural compensation, reduce the cost, and reduce the thrust of fixed pier.
3、将管线在固定墩处分为多个相对独立的局部,在两固定墩之间设排潮管(好为两套),则排潮管既能扫除湿润气体,又可作为日常运转的信号管,可随时监测管网运转状况。
3. If the pipeline is divided into several relatively independent parts at the fixed pier and two sets of tidal drainage pipes are installed between the two fixed piers (preferably two sets), the tidal drainage pipes can not only remove wet gas, but also serve as signal pipes for daily operation, and can monitor the operation of the pipeline network at any time.
4、外滑动构造可依据需求改形成抽真空构造。
4. External sliding structure can be changed into vacuum-pumping structure according to demand.
