Welding (Cooling) Blankets
Proline’s Welding (Cooling) Blankets minimize cracks while welding steel pipes by gradually lowering the temperature of welded metal pipes. They also act as a protective barrier to keep your crew from burning themselves.
Blankets are made with a canvas exterior and lined with 1” fiberglass insulation and glass cloth for superior heat protection. The elastic strap makes them easy to secure, and an S-hook ensures a tight fit to your pipes.
| Size (Width) | 9” - 12” |
| Size (Length) | 21” - 165” |
| Size (Diameter) | 3” - 48” |
| Material | Canvas exterior with 1” fiberglass insulation and glass cloth liner |
| Temperature Rating | 1,000 - 1,500°F (538 - 815°C) |
The layers help slow heat dissipation from the weld, allowing it to “cure.”
The 1” fiberglass cloth is the layer that comes into contact with a weld because it has the highest temperature resistance.
The canvas exterior layer is not exposed to hotter temperatures and does not have the same heat resistance.
