AVS Industries manufactures a diverse portfolio of hot work protection fabrics. Select the hot work (welding) protection fabric that meet your needs!
Hot work operations apply to all riveting, grinding, welding, flame cutting or other fire or spark-producing operations. These processes typically require special permits and procedures to prevent the ignition of vapors, liquids and solids that may be in or near the work area. E-Glass based Fiberglass and Silica (>95% SiO2) fabrics are the two types of protection fabrics typically used for hot work operations. A brief review of the fabrics is provided below.
Fiberglass (E-Glass) | AVSil® Silica | Technical Information |
|
---|---|---|---|
Melt Point | 1500°F 816°C | 3000°F 1649°C | Higher is better |
Silica Content (%) | 54 - 56% | >95% | Higher is better |
Molten Metal Hold Out | Marginal | Excellent | Improves with fabric weight/thickness |
Dermatitis Issues | Yes | No | Uncoated and vermiculite coated fiberglass commonly have this issue |
Reusability | Low | High | Better with silica fabrics but depends on hot work practices |
Fireproof | No | Yes | Silica won't burn or degrade when exposed to flame or high temperatures |
What kind of protection fabric are you looking for?
Severe Hot Work Operations
- Close proximity horizontal welding protection
- Provides excellent molten metal hold-out
- Best for extreme hot work operations
- Welding protection fabrics classified as “Welding Pads”
Moderate Hot Work Operations
- Large drop height horizontal welding protection
- Provides good molten metal hold-out
- Best for standard hot work operations with lower level of molten metal
- Welding protection fabrics classified as “Welding Blankets”
Light Hot Work Operations
- High level of welding sparks
- Best for standard hot work operations requiring vertical (curtain) protection
- Welding protection fabrics classified as “Curtains”
