Smooth Epoxy Fiberglass Tube Knitting And Pultruded / Hollow Fiberglass Tube
Product
1.The feature of Smooth Epoxy Fiberglass Tube Knitting And Pultruded / Hollow Fiberglass Tube
Tubes using glass fiber as insulation material have good insulation performance and mechanical strength. It is typically used for power system isolation and protection of wires, cables, or pipelines. The manufacturing process of glass fiber insulated hollow pipes generally includes the following steps:
1. Glass fiber preparation: Select suitable glass fiber materials, usually using E glass fiber (E-Glass) or S glass fiber (S-Glass). Glass fibers can be continuous or chopped fibers.
2. Fiber weaving: Weaving glass fibers to form a hollow tubular structure. Weaving can adopt different weaving methods and densities to achieve the required insulation performance and strength.
3. Adhesive coating: Apply adhesive to the woven glass fiber tube to enhance the bonding force and overall strength between fibers.
4. Curing: After coating with adhesive, the glass fiber pipe is cured, usually using heat treatment or chemical curing methods to ensure the stability and strength of the insulation pipe.
5. Cutting and shaping: Cut the cured fiberglass insulation pipe into the required length and perform necessary shaping treatment to ensure that the size and appearance of the pipe meet the requirements.
6. Inspection and testing: Conduct quality inspection and performance testing on glass fiber insulated pipes, such as electrical insulation performance, mechanical strength, etc. Glass fiber insulated hollow pipes have excellent electrical insulation, heat resistance, and corrosion resistance
