HTFM Stress Relief Pads

Wilson Industries Stress Relief Pads are made from special non-asbestos, resilient, high-temperature materials. Non-combustible and chemically inert, they provide temporary insulation of welds during stress relieving of large diameter piping, ducts, vessels or tanks. Available in 12”, 24” or 48 ” widths and 1”, 1.5”, 2” thicknesses.

What is Stress Relief?
Welding often requires the precise monitoring of temperature to ensure that the heating and cooling of metal is done in a gradual manner that protects the integrity of the material. After a weld, the welded metal’s temperature is naturally different than the surrounding metal. The stress relief process creates a consistency in the metal structure cooling process.

During stress relief, a thick insulation blanket is placed around the welded portion of metal. Once peak temperature is reached, it is maintained for a set period of time defined by the thickness of the weld, which strengthens the bond.

The metal is then slowly cooled down to ambient temperature. Temperature changes during both heating and cooling must be carefully controlled. Too-quick temperature change could cause the metal to become distorted and later develop cracks that could lead to failure.

Wilson Industries offers blankets that provide an excellent stress relief solution.
