管托分類(lèi)

管托也分為保溫(保冷)與不保溫的

不保溫的直接被叫做support 也就用在常溫管道；

保溫（保冷）的就被稱作為pipe-shoe

無(wú)論是否保溫都可以分為滑動(dòng)，固定，導(dǎo)向，不管選擇那一種，管托是不變的，只是在

管托與鋼結(jié)構(gòu)或支架的連接改變。

通?；瑒?dòng)和導(dǎo)向型式的管托采用四氟板與四氟板滑動(dòng)摩擦，或者白鋼板與四氟板滑動(dòng)摩擦，以減小摩擦系數(shù)，降低管道在變形或移位時(shí)，管架對(duì)管道的束縛應(yīng)力，并且盡量避免管托與管道之間的相對(duì)位移。

高密度管托系由異氰酸鹽與聚醚為主，再加上發(fā)泡劑、觸媒和防火劑，經(jīng)高速攪拌混合反應(yīng)生成的具有塑膠、橡膠和軟木特性的發(fā)泡聚合體。

泡體是由成千上萬(wàn)極微小均勻的獨(dú)立細(xì)胞組成，呈立體蜂窩式的結(jié)構(gòu)。其熱傳導(dǎo)率低、抗壓強(qiáng)度高、吸水率低，有瀝青木制品及其他類(lèi)襯墊物難以比擬的優(yōu)良性質(zhì)，是深冷管道管托、鞍座及低溫設(shè)備墊塊的理想材料。在國(guó)內(nèi)及歐美國(guó)家用于石油化工基地、LNG液化氣廠、冷鏈基地及中央空調(diào)系統(tǒng)之管托、支吊架及墊塊等。

High density PU pipe support is a new kind of foaming polymer with the features of plastic, rubber and softwood. It is created through high speed stirring with the main raw material of isocyanate and polyether added with vesicant, catalyst or flame retardants. The foaming body is a structure like a three-dimensional honeycomb, which is made up of ten thousands of isolated cells. It has low thermal conductivity, high compressive strength, and low water adsorption, it has excellent properties which asphalt-wood products and other pads difficult to compare. It’s ideal material for cold pipe supports and equipment pads. It is used as pipe supports, cradles and equipment pads in petrochemical industry, LNG liquefied gas factory, cold-chain base and central air conditioner both in domestic and foreign.
