摘要
近年来,无论是高温管道还是低温管道的管托,不仅要求具有支承强度,而且要求具有隔热性和耐燃性。为此,本文介绍了几种国外的高、低温管道的隔热管托:(1)套管型保温管托:(2)蛭石耐高温管托;(3)NHK耐火管托;(4)NHK聚氨酯隔热管托;(5)FRU隔热管托。另外,对隔热管托的安装方法也作了简介。
In recent years, no matter what type of pipe brackets have been used in high temperature or in low temperature, not only the support capacity but also the property of thermal insulation and fire-resistance are needed. Some foreign pipe brackets used in high or low temperature are intro- duced in this article: (1) Sleeve type thermal insulation pipe bracket; (2) Vermiculite high temperature resistant pipe bracket; (3) NHK fire resistant pipe bracket; (4) NHK polyurethane thermal insulation pipe bracket; (5) FRV thermal insulation pipe bracket. In addi- tion, the installation method for the thermal insulation pipe brackets are introduced in the article.
