Product Description
Product structure of steel-jacketed steel insulation pipes
Steel jacketed steel insulation pipes are usually composed of the following three main parts:
1.Working steel pipe
* The working steel pipe is the core part of the steel-jacketed steel insulation pipe and is responsible for transporting media such as steam and hot water.
* Generally, seamless steel pipes, spiral seam steel pipes or straight seam steel pipes are adopted. The material is selected based on the characteristics of the conveyed medium and engineering requirements. Common materials include carbon steel, alloy steel, etc.
* The selection of its pipe diameter and wall thickness depends on parameters such as flow rate, pressure and temperature.
2.Insulating layer
* The insulation layer is located between the working steel pipe and the outer protective steel pipe and plays a key role in reducing heat loss.
* Commonly used insulation materials include polyurethane foam, glass wool, rock wool, aluminum silicate fiber,aerogel felt etc. These materials have good insulation performance and heat insulation effect.
* The thickness of the insulation layer is designed and calculated based on the usage environment of the pipeline, the temperature of the medium and the insulation requirements to ensure the expected energy-saving effect is achieved.
3.Outer protective steel pipe
* The outer protective steel pipe is wrapped outside the insulation layer to provide protection for the working steel pipe and the insulation layer
* Usually, spiral steel pipes or straight seam steel pipes are adopted, and the materials are generally carbon steel.
* The outer protective steel pipe can prevent mechanical damage, corrosion and water intrusion from the outside, thereby ensuring the long-term stable operation of the pipeline.
