A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.

A laminate structure comprises a protective layer and a backing structure. The backing structure comprises a first support layer comprising an aerogel and a second support layer comprising a polymer and is arranged so that the second support layer is provided between the protective layer and the first support layer.

A flexible insulation material may be configured to substantially reduce the amount of radiation transmitted therethrough by incorporating a reflective mat of high temperature fibers that withstand temperatures of at least 500° C. The flexible insulation may be stored and used over temperatures ranging from −270° C. to 5000° C. The mat may have optical properties to produce a transmittance of no more than 5% over a range of temperature from 500° C. to 5000 vC. The mat may include high temperature fibers such as carbon and/or silicon carbide and these fibers may be coupled by a binder in a non-woven fabric.
