一、概述:供热管道直埋技术,是当前世界技术发达国家在集中供热管道的设计与施工中采用的一种先进技术,予制保温管是大力推广直埋技术的一种行之有效的、新型的管道材料。它具有占地面积小,施工进度快:保温性能好、使用年限长、工程造价低、以及减少与其它地下管线交叉机会的优点,它具有简单、坚固、安全、可靠等特点、这种予制保温管的推广和使用、将会极大地提高热力管道施工的标准化、工厂化和装配化程度,对我国发展集中供热事业具有十分重要意义。
I. Overview: Directly buried heating pipe technology is an advanced technology used in the design and construction of centralized heating pipelines in the world’s technologically advanced countries. Pre-insulation pipe insulation is an effective method for promoting direct-buried technology. New pipeline materials. It has the advantages of small floor space, fast construction progress, good insulation performance, long service life, low construction cost, and the opportunity to reduce crossover opportunities with other underground pipelines. It is simple, sturdy, safe and reliable. The promotion and use of thermal insulation pipes will greatly improve the standardization, factoryization and assembly of thermal pipeline construction, and will be of great significance to the development of centralized heating in China.
