With the continuous development of technology, in the process of many high-rise residential construction, can better for such a kind of directly buried insulating pipe material used is very important. Because it is used as in more aspects of the point. Mainly in the process of ventilation or water and electricity installation, can bring about some development.
First of all, for the performance of directly buried insulating pipe are better, and safety, good quality and the effect of heat preservation is good, able to resistance to high temperature low temperature under different conditions, so such a material, quickly is also in the relevant technical support better able to develop and update. For this kind of material technology, mainly is for the related practical to reflect.
For the directly buried ?
