管托分类

管托也分为保温(保冷)与不保温的

不保温的直接被叫做support 也就用在常温管道；

保温（保冷）的就被称作为pipe-shoe

无论是否保温都可以分为滑动，固定，导向，不管选择那一种，管托是不变的，只是在

管托与钢结构或支架的连接改变。

通常滑动和导向型式的管托采用四氟板与四氟板滑动摩擦，或者白钢板与四氟板滑动摩擦，以减小摩擦系数，降低管道在变形或移位时，管架对管道的束缚应力，并且尽量避免管托与管道之间的相对位移。

高密度管托系由异氰酸盐与聚醚为主，再加上发泡剂、触媒和防火剂，经高速搅拌混合反应生成的具有塑胶、橡胶和软木特性的发泡聚合体。

泡体是由成千上万极微小均匀的独立细胞组成，呈立体蜂窝式的结构。其热传导率低、抗压强度高、吸水率低，有沥青木制品及其他类衬垫物难以比拟的优良性质，是深冷管道管托、鞍座及低温设备垫块的理想材料。在国内及欧美国家用于石油化工基地、LNG液化气厂、冷链基地及中央空调系统之管托、支吊架及垫块等。

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.
