Guardian of Welding Safety: A Guide to the Correct Selection and Use of Welding Fire Blankets
On construction sites where sparks fly, a seemingly ordinary yet crucial safety material silently safeguards personnel and equipment—the welding fire blanket. Specifically designed for welding scenarios, this flame-retardant material has become an indispensable part of modern industrial safety operations.
Welding Fire Blankets: The Safety Barrier on the Welding Site
Welding fire blankets, also known as welding-resistant blankets or flame-retardant blankets, are safety materials specifically used for occasions prone to sparks, such as welding. They effectively block flying sparks, slag, and weld spatter, serving to isolate work areas and separate work layers, fundamentally eliminating fire risks that may arise during welding operations.
This material not only protects onsite personnel and equipment but can also be used as a light barrier, helping to create a safe, clean, and standardized workspace. Depending on the size of the welding sparks and slag, users can choose from different specifications of welding fire blankets. Common types include acrylic-coated fiberglass cloth, silicone-coated fiberglass cloth, polyurethane-coated fiberglass cloth, among others.
Purchasing Guide: Two Key Indicators Cannot Be Ignored
High-Temperature Resistance is the Primary Consideration
A qualified welding fire blanket must possess excellent high-temperature resistance. The professional test method involves using a blowtorch at a distance of 20-30 mm perpendicular to the blanket at full force for 30 minutes. Products that do not burn through or ignite are considered qualified.
Warp and Weft Density Determine the Safety Level
The warp and weft density of the fire blanket directly affects its protective performance. Products with overly sparse density have poor sealing performance, which may lead to slag penetrating the blanket and causing burn injuries. It is essential to carefully check the fabric density during selection to ensure complete safety.
SUNTEX Welding Fire Blankets: Six Major Features Set the Industry Standard

Extended Applications: The Broad Horizon of Fireproof and Thermal Insulation Materials
Beyond welding fire blankets, similar fireproof and thermal insulation materials are also shining in various industrial fields. Fireproof thermal insulation blankets feature fireproof, waterproof, anti-corrosion, high-temperature resistance, and easy disassembly characteristics, widely used in industries such as oil platforms, ships, and chemical plants. High-temperature models can be equipped with an additional stainless steel wire mesh, with maximum temperature resistance reaching above 1200 degrees Celsius.
Removable pipe insulation jackets (insulation blankets, insulation covers) are currently high-end insulation materials for pipes and equipment. They are widely used in thermal equipment and various pipelines in fields such as petroleum and chemical industries, power generation, and metallurgy. They are suitable for insulating various complex-shaped equipment and components.
Safety is no small matter. Choosing a qualified welding fire blanket is an act of responsibility towards the lives of operators. As industrial safety standards continuously improve, the technology and quality of welding fire blankets are also constantly upgrading. Only by fully understanding product characteristics and strictly ensuring quality control can we truly guarantee the safe and efficient execution of welding operations.
Whether for large-scale industrial sites or small repair jobs, investing in a high-quality welding fire blanket is like taking out a solid "insurance policy" for safety.
