Storage of Thermal Insulation Steel Pipe in Winter

In winter, the temperature is below zero and extremely cold. How do insulating steel pipes spend the winter in freezing season? Some people will ask that the insulation steel pipe means to stop the insulation protection of the medium inside the insulation steel pipe, but if it is the open-air insulation steel pipe that has been produced, how can it be stored so that they can survive the winter safely?

Insulating steel pipes are usually stored at room temperature to prevent direct sunshine, but how to keep them in winter when the uniform temperature is about 0 degrees? Superstition is like this. After the beginning of winter, the insulating steel pipes are laid uniformly according to certain rules and placed in the workshop. Then they are completely covered with rayon cloth to prevent the insulating steel pipes from indirectly contacting the sunshine. The rayon cloth should not be moved between the arrival of spring so as to prevent the outer skin of the insulating steel pipes from cracking.

The commonly used insulation material for jacket polyurethane insulating steel pipe is rigid polyurethane foam, and the applicable temperature is - 185 - 120 C. In order to improve its strength, a layer of high density polyethylene (HDPE) is added to the thermal insulation layer to form a composite data structure to prevent groundwater from seeping into the thermal insulation layer. The construction of jacket insulation pipe mainly includes task steel pipe layer, polyurethane insulation layer and high density polyethylene maintenance layer. One of the inner layers is covered by black or yellow polyethylene plastic materials prefabricated to a certain wall thickness.
