Although they have insulation layer, but if the temperature is too low, it may be in the pipes freeze water, water becomes ice volume increases, is likely to be the pipe donglie.
虽然它们有保温层，但如果温度过低，也可能将管子里的水冻上，水变成冰体积增大，很有可能将管子冻裂。

Composite silicate insulation material plasticity, low thermal conductivity, high temperature resistant, low pulp drying shrinkage rate, etc.
复合硅酸盐保温材料可塑性强、导热系数低、耐高温、浆料干燥收缩率小等特点。

It can solve the difficulty of lowinsulation resistance of high temperature strain gage adhesives and can raise the accuracy of high temperature strain measurements.
