PREHEAT, POST WELD HEAT TREAT / SLOW COOL BLANKETS
Preheat Blankets
Preheating reduces the risk of cracking in weld metal and heat affected zones. Our stocked preheat blankets and pads are offered as a 1/2" thick blanket, 6" and 12" wide x 10' and 20' lengths. All multi-layered preheat blankets are made with cut lines to allow a cut on the job site for quick resizing without fray.
All of our preheat blankets are fabricated with our high-quality fiberglass fabric, best suited for steady state temps of 1000°F and below.
We also offer custom sized preheats blankets to fit your needs.

PWHT/Slow Cooling Custom Blankets
PWHT/Slow cooling custom blankets are the ideal solution to eliminate welding cracks while welding on pipe. Rapid cooling can create cracks in a pipeline, especially when exposed to wind, drafts, rain and snow. Pyro Shield’s slow cool blankets are designed to gradually lower the temperature of welded metal pipes to prevent hydrogen cracking. Our slow cool blankets are also used as a protective measure to prevent workers from burning themselves.
Our Pyro Shield slow cool blankets can be custom made to fit your application and offer you the best, most cost-effective solution while eliminating skin-irritating, and unfriendly fiberglass insulation. Pyro Shield also offers an open wrap which allows you to easily wrap around drill collars and secured with straps. These wraps can also be lined with stainless steel wire mesh to extend the life of your wrap and protect the silica fabric from wearing overtime.
We also offer a closed end bag designed to easily slip over the tool joint and secures in place with Velcro straps, ties or d-rings. Our Pyro Shield slow cooling bag can be lined with stainless steel wire mesh to help extend the life of the bag and to protect the silica fabric from wearing overtime.
