What is insulated steel pipe?

Insulated steel pipes are steel pipes that, after being processed by thermal insulation technology, can ensure that the internal temperature and surface temperature of the working steel pipe meet or meet the usage requirements under the action of different working environments and external media.

It has good thermal insulation properties, can effectively reduce energy loss, and plays an energy-saving role in the process of transporting liquids. At the same time, insulated steel pipes also have the characteristics of good chemical stability and excellent anti-corrosion properties, which can prevent corrosion and reduce the aging rate of pipelines to a certain extent. In addition, insulated steel pipes are easy to construct and can be quickly laid and connected on site, greatly shortening the construction period. They have a long service life of more than 20 years, reducing the cost of maintenance and replacement of pipeline equipment.

The structure of insulated steel pipes usually consists of working steel pipes, insulation layers and outer sheaths. The working steel pipe is responsible for transporting the medium, the insulation layer plays the role of insulation, and the outer sheath protects the insulation layer to ensure that it is not affected by the external environment. There are various types of insulation steel pipes. According to the different insulation structures, they can be divided into internal sliding type and external sliding type.

Insulated steel pipes are widely used in liquid and gas transportation pipe networks, chemical pipeline insulation projects, petroleum, chemical industry, central heating networks, central air conditioning ventilation pipes, municipal engineering and other fields. By using insulated steel pipes, these industries can reduce heat loss, improve energy efficiency, and reduce operating costs.

In general, insulated steel pipe is a pipe material with excellent performance and wide application. It plays an important role in ensuring the stability of medium transportation temperature, improving energy utilization efficiency, and reducing operating costs.
