What're the advantages of epoxy glass fiber winding pipe?

1. Strong impact resistance Epoxy glass fiber winding pipe adopts the weaving process of inner braided layer, middle longitudinal layer, middle winding layer and outer braided layer. The inner layer and the outer layer are braided layers, and the middle layer is a combination of longitudinal and hoop directions. Because the braid angle is generally greater than 90°, the circumferential stiffness i...

What're the main indicators that affect the performance of insulating pipes?

1. Insulation resistance and resistivity Resistance is the reciprocal of conductance, and resistivity is the resistance per unit volume. The less conductive the material, the greater its resistance, and the two are in a reciprocal relationship. For insulating materials, it is always desirable to have the highest resistivity as possible. 2. Relative permittivity and dielectric loss tangent There ar...

How to avoid the rapid aging of epoxy pipe？

Epoxy pipe is a kind of insulating material. Its insulating performance is closely related to temperature. The higher the temperature, the worse the insulating performance. In order to ensure the insulation strength, each insulating material has an appropriate high allowable operating temperature. Below this temperature, it can be used safely for a long time, and it will age quickly if it exceeds ...
