How To Apply Aerogel Insulation Blanket In Petrochemical Industry

Joda aerogel insulation blanket is mainly used for the thermal insulation of heavy oil high temperature steam injection production pipeline and the thermal insulation of medium pipeline in refining and chemical unit. The general temperature is between 200 ~600. Lightweight aerogel products can effectively reduce the amount of external insulation layer, reduce the overall cost, and it has excellent hydrophobicity, hydrophobicity (> 98%) and pH value is neutral, will not corrode the insulation pipeline, thus prolonging the service life of the construction object, and reduce maintenance costs in the later period. The same thermal insulation effect, the use of aerogel thermal insulation felt can effectively reduce the volume of construction objects, thereby significantly improving the distribution rate of pipelines. Now the industrial transportation heat supply pipeline, the pipeline temperature from tens of degrees to 600 degrees. These pipes are widely used in thermal insulation engineering, such as aluminosilicate magnesium materials and glass fiber materials. About 30 years ago, rock wool and mineral wool materials were mostly used in thermal insulation projects. Now, rock wool thermal insulation has been eliminated in industrial thermal insulation projects. In the construction performance, waterproof performance and other aspects are not very different, the main reason for being eliminated is the difference in thermal conductivity.

The problems of insulation engineering in China now are:

Insulation structure is unreasonable, insulation thickness is not standardized, insulation construction is not in place.

It is easy to be deformed and settled, has poor thermal stability, high damage rate and poor heat preservation effect in the later period, which can not meet the technological requirements.

The insulation effect is poor and the drop is obvious, which leads to the maintenance cost of thermal insulation engineering and the operation cost of equipment.

Life expectancy is basically 3~5 years, and all of them need to be replaced at maturity.

It is not completely waterproof, easy to absorb water and absorb moisture and corrode pipes.

For pipes with a temperature of more than 100 degrees, the insulation layer should be at least more than 200 mm thick, with high heat flux density and high heat loss.

The benefits of Joda aerogel insulation materials:

The heat insulation effect is 2-5 times that of the traditional thermal insulation material, and its advantages are more obvious at high temperature and longer life.

The material as a whole hydrophobic, can effectively prevent moisture from entering the pipeline, equipment, and has A1 fire performance.

Lightweight, easy to cut, sew to adapt to various shapes of pipes, equipment insulation, and installation time and less manpower.

Less package volume and lighter weight can greatly reduce the transportation cost of thermal insulation materials.

While keeping the equipment warm, it can also play the functions of sound absorption, noise reduction, vibration buffering and so on, improve the environmental quality and protect the equipment.

Only 1/2 to 1/5 of the thickness of traditional materials can achieve the same thermal insulation effect, heat loss is very small, high space utilization.
