Types of Fiberglass Sleeving
Fiberglass electrical insulation tubing
This tubing is manufactured from glass fiber yarn and is designed to provide electrical insulation in high-temperature conditions. It is commonly used in industrial, automotive, and aerospace applications where Dielectric properties and Chemical resistance are essential.
E-Glass fiberglass tubing
E-Glass fiberglass tubing is made from electrical-grade glass fibers. It is characterized by its good electrical insulation properties. They have excellent mechanical strength and are heat-resistant up to 300°C. They are also chemical and moisture resistant. All these make them ideal for use in electrical insulation, particularly in motors and transformers.
S-2 glass fiberglass tubing
S-2 tubing is made from S-2 glass fibers with enhanced mechanical and dielectric properties. Their temperature and corrosion resistance make them ideal for critical aerospace and defense applications where failure risks cannot be tolerated.
Heat-shrinkable fiberglass sleeve
This is a fiberglass sleeve that can shrink in response to heat. It provides a tight, insulating, and protective fit over wires, cables, and components. This functionality makes it ideal for situations where a tighter fit is required for effective insulation, such as on irregular shapes or in spaces with limited access.
The fiberglass casing should not be stacked directly on the ground, on the steel frame or on the cement floor. The brackets generally used to place steel pipes are not very suitable for fiberglass sleeves.
Use support bars between the bottom layers and layers to prevent damage and movement of the glass fiber sleeve. For fiberglass heat sleeve with a length of 9.14m, at least 4 support bars should be used. The support bars should not be placed in the transition area of the pipe or In the thickened area, the spacing of the support bars should not exceed 1.8m, and should be arranged vertically with the pipe body. At the same time, the thickness of each layer should be uniformed. The tubes used for the support bars should be softer than the tubes. near both ends of the fiberglass sleeve.
The fiberglass sleeve should not be stacked too high to ensure the safety of the pipe and facilitate inspection and loading and unloading.
The layers should be staggered to prevent the pipe joint from bearing too much weight.
Maintain a Fiberglass Sleeving
Inspect Regularly
It is essential to inspect the fiberglass heat shield sleeve regularly for any signs of damage, wear and tear, fraying, or loss of material properties. Inspect the sleeve from end to end and look out for any discoloration, tears, or small cracks that may lead to failures.
Clean Thoroughly
Regular cleaning is necessary to maintain the functionality and hygiene of a fiberglass heat shield sleeve. Use a mild soap, warm water, and a soft cloth or brush to clean the sleeve. Avoid using any harsh chemicals, abrasive materials or high-pressure water jets, as they can damage the sleeve surface.
Replace Damaged Sleeves
After inspecting the sleeve, if you find a damaged, worn or torn area, it is important to replace it immediately. Damaged sleeves can reduce the effectiveness of protection and potentially increase the risk of hazards to personnel and equipment.
Application of Fiberglass Sleeving
