Prefabricated direct buried insulation steel pipe knowledge

What brand of prefabricated directly buried thermal insulation steel pipe quality is better, not only has the leading process and application performance that can not be compared with that of pipe trenches and laying pipes in the past, but also has obvious social value and economic benefits, and is also a powerful countermeasure for heating energy saving. What kind of choice is appropriate, let's take a look

Prefabricated directly buried thermal insulation steel pipe selection

The selection of directly buried heating pipeline process means that the progress of domestic heating pipeline technology has now entered a new journey. With the further improvement and progress of this leading technology, it is urgent to replace pipe trenches and laying heating pipes directly buried.

As a key building material in real life, prefabricated directly buried thermal insulation steel pipe has been widely used in different housing construction, and this kind of thermal insulation pipe can reasonably protect the temperature of a place.

In the process of transportation and assembly and its use, the thermal insulation steel pipe has been recognized by more and more people, so what is its internal structure?

Construction of directly buried thermal insulation steel pipe

Is the steel pipe layer, this structure is fully in accordance with the actual requirements of the user to complete the development of the surface of the steel pipe generally after the rust removal process. Production or planning is then completed according to the level of difference.

The two-layer structure is the insulation layer of prefabricated directly buried thermal insulation steel pipe, which is generally a plastic foam that produces some differences between the steel pipe and the outer layer with a foaming machine. Then all of this liquid is poured into it, so that it can play the function of heat preservation.

The third layer is a high-density polyethylene material, which is generally used in it. Its key function is to protect the insulation layer of the overall polyurethane insulation pipe, prevent damage by other foreign bodies and direct damage, in addition, it can reasonably play a waterproof and radiation protection function.

Prefabricated directly buried insulation pipe has a very good feature, its water absorption is very low. The water absorption of polyurethane foam is very low because it has a high closed cell ratio of 92%.

Low thermal conductivity, low water absorption, good insulation and waterproof performance of high-density polyethylene or fiberglass wrap anti-corrosion layer 3 anticorrosion, good insulation performance, long service life.

Prefabricated directly buried insulation pipe its foam hole is sealed, water absorption is very small. The outer casing high-density polyethylene shell and glass fiber reinforced plastic shell have good anti-corrosion, insulation and mechanical properties.

Therefore, the outer skin of the working steel pipe is difficult to be eroded by external air and water. As long as the water quality in the pipe is well treated, the service life of the prefabricated directly buried insulation pipe can reach more than 50 years.
