Thermal Blanket Insulation for the Process Industries

Removable, reusable protective jacket the insulation solution
to problem insulation areas on all types of steam process equipment. The removable, reusable features of SHANNON insulation blankets drastically lower operation costs, shorten down time, save valuable energy, improve the work environment and reduce labor costs associated with installation, removal, and reinstallation. a custom designed, self-contained insulation system
This means quality construction for specific application needs, quality designs retrofitted to field conditions and design features which make SHANNON insulation blankets user-friendly to the field mechanic.

...utilizes CAD technology
for maximum design accuracy. Through years of information gathering, standardized designs as well as custom designs are possible for all types of equipment. Our CAD file base includes standardized designs on gate valves, condensate pumps, pressure reducing valves, slip and bellows expansion joints, vall joints, strainers and steam traps. Even the most difficult geometric surfaces such as steam turbines can be engineered for blanket treatment. self-contained insulation system
constructed of a high density insulation filler with a fully encapsulated outer jacketing. The outer jacketing is double sewn and bound at the closing seams. The jacketing and sewn construction ensure long lasting protection to the insulation filler.

...can withstand extreme conditions
such as steam tunnels and manholes. High chloride environments with high humidity and possible flooding have little or no effect on specific blanket designs. SHANNON offers a wide range of specialty designs to accommodate these extreme conditions.

...comes equipped with all necessary fastening hardware.
The fasteners are an integral part of the blanket design and become the dominant feature in making installs and removals quick and easy. All metal hardware is stainless steel for added strength and durability. Velcro can be sewn into both the belting system as well as to the outer jacketing flap.
