As a common insulation material, rubber and plastic tube shell has been widely used in the field of pipe insulation because of its good insulation performance and long service life. Does the pipe need additional protective layer after insulation with rubber and plastic shell?

First of all, let's understand the role of rubber and plastic shell. Rubber and plastic tube shell is made of rubber and plastic as the main materials. It has good thermal insulation performance, which can reduce the heat loss of the pipeline and improve the energy utilization efficiency. In addition, the rubber and plastic shell also has waterproof, heat insulation and fire protection functions, which can protect the pipeline from the outside environment.

However, in some cases, the rubber shell requires an additional protective layer to enhance its durability and corrosion resistance. Here are a few situations to consider adding a protective layer:

1, mechanical protection: In some industrial places, the pipeline may be subjected to mechanical impact, collision or extrusion forces. These external forces may lead to the damage or deformation of the rubber shell, and then affect its insulation effect. Therefore, in this case, adding a layer of mechanical protection can play a protective effect, such as the use of glass fiber cloth or polyethylene film to increase the durability of the rubber shell.

2, anti-corrosion protection: In some chemical, petroleum and other fields, pipelines may be eroded by corrosive media. Even if the rubber shell itself has certain corrosion resistance, long-term contact may still cause damage. In order to increase the life of the pipe, a layer of anti-corrosion coating can be coated on the surface of the rubber tube shell to provide additional anti-corrosion protection.

3, ultraviolet protection: when the pipeline is exposed to outdoor or direct sunlight, ultraviolet radiation may lead to aging, hardening or brittleness of rubber and plastic materials. In order to protect the rubber tube shell from ultraviolet rays, a layer of light stabilizer or aluminum foil can be added to the outer layer to provide effective ultraviolet protection.

Although the rubber shell itself has various advantages, under specific environmental conditions, in order to enhance its durability and corrosion resistance, it is very important to add a protective layer. This can ensure the long-term stable operation of the pipeline and maintain a good insulation effect.
