Fireproof Blanket
Fireproof Blanket (or Fire Retardant Blanket) is a flexible, woven fabric material designed to resist burning, prevent the spread of fire, and provide thermal protection in industrial environments. These blankets serve two main purposes: passive fire safety (to smother flames or protect equipment from sparks) and thermal stress relief (to retain heat during welding or stress-relieving operations).
Main Chemical Compositions & Categories
Fireproof blankets are made from inorganic materials chosen for their high MST and non-combustibility. The required application (welding vs. continuous heat) dictates the specific material.
| MATERIAL BASE | FIBER TYPE | TYPICAL MST (Continuous) | PRIMARY APPLICATION FOCUS |
| Fiberglass | Woven Fiberglass | ~550°C (1022 F) | Spatter/Spark Protection, general fire smoldering. (Most common and economical). |
| Silica | High-Purity Amorphous SiO2 | ~980°C (1800 F) | Heavy-Duty Welding/Torch Protection, high radiant heat barrier. |
| Ceramic Fiber | Aluminum Silicate (RCF) | ~1260°C (2300 F) | Stress-Relieving Insulation, maximum thermal retention. |
Key Performance Metrics
| PROPERTY | TYPICAL PERFORMANCE | MECHANISM OF ADVANTAGE |
| Non-Combustibility | EXCELLENT | All materials are inorganic and will not burn or fuel a fire. |
| Molten Metal/Spark | HIGH RESISTANCE | Tightly woven fabric provides a physical barrier and sheds hot particulates. |
| Thermal Insulation | VARIES | Thickness and material determine ability to trap heat (Ceramic Fiber is best for this). |
| Flexibility | GOOD | Allows the blanket to be draped, wrapped, or hung to conform to complex shapes. |

Applications and Key Characteristics
The utility of fireproof blankets is split between workplace safety and process efficiency.
- Safety and Containment (Welding/Grinding): These blankets are used to shield adjacent equipment, walls, and flammable materials from sparks, slag, and molten spatter during hot work (welding, cutting, grinding). They are a critical component of fire prevention plans.
- Fire Suppression (Emergency): Lightweight versions (often fiberglass) are used to smother small, incipient fires (especially on clothing or small spills) by cutting off the oxygen supply.
- Thermal Stress Relief (Post-Weld Heat Treatment, PWHT): Thicker, high-MST ceramic fiber versions are specifically used in metal fabrication to wrap welded components, ensuring the heat is retained and dissipated slowly and uniformly. This prevents localized thermal stress and micro-cracking, which is essential for code compliance in high-pressure vessels and piping.
- Curtains and Shields: They are often hung as thermal or radiant heat shields near furnaces or high-temperature equipment to protect workers or sensitive instrumentation from extreme heat exposure.
Typical Industries and Applications
Fireproof blankets are ubiquitous in heavy industry:
- Welding and Fabrication: Protecting nearby equipment and floors from hot sparks.
- Foundry and Metallurgy: Protecting hoses, cables, and personnel from radiant heat and molten metal splashes.
- Petrochemical and Power: Used during outages for PWHT on critical pipe welds, and as safety curtains.
- Laboratories: Used as emergency fire covers.
Key Data Sheet Properties to Consider
Selection is based primarily on the hazard to be protected against:
- Maximum Service Temperature (MST): Must match the temperature of the heat source (e.g., use Silica for proximity to torches, Fiberglass for general welding sparks).
- Weight/Thickness: Lighter blankets are easier to handle for vertical shielding; heavier blankets provide better thermal insulation for PWHT.
- Coating/Treatment: Look for Acrylic or Silicone coatings for enhanced water resistance and abrasion resistance, although the silicone coating may burn off at high T.
Technical Guidance: When selecting a blanket for molten metal splash, ensure the material is rated to shed the metal (like a silicone-coated fiberglass) rather than absorb it. When used for PWHT, multiple layers of a high-temperature blanket (e.g., RCF) are typically required to meet the necessary thermal retention rates.

❓ Frequently Asked Questions (FAQ)
Question | Elaborated Answer |
Q: What is the Refractoriness Under Load (RUL) of your refractories? | A: Refractoriness Under Load (RUL) is a critical property that defines the maximum temperature our materials can withstand while under compressive stress before deforming (softening). Since we offer a wide range of materials—from Alumina-Silicate Bricks to high-performance Silicon Carbide Bricks—the RUL varies significantly. For specific product data, please refer to the product data sheet or submit a quote request for the material you are interested in. |

Q: How should I choose the appropriate refractory material for my application? | A: Selecting the correct refractory is paramount to process efficiency. The choice depends on three key factors: 1. Operating Environment: Maximum process temperature and thermal cycling (shock). 2. Chemical Attack: Type of slag, molten metal, or corrosive gas being handled (acidic, neutral, or basic). 3. Mechanical Stress: Abrasion, erosion, and static load requirements. We recommend utilizing our detailed refractory solutions service to consult with our engineers for an optimized, application-specific recommendation. |
Q: Which monolithic material should I choose when patching an existing lining? | A: For patching and minor repairs, the ideal monolithic material depends on the parent lining material, the patching depth, and the need for a rapid return to service. Common choices include: Refractory Mortars & Mixes (for minor joints/surfaces) or Plastic Refractories (for areas requiring physical compaction). Always choose a patch material chemically compatible with the existing lining to ensure proper bonding and service life. |
