An insulation arrangement in which a sheath (2) having at least one thin deformable wall (3), for example of foil, contains a powder insulating material (10), with a high vacuum within the sheath. The vacuum can be drawn through an opening (8) after a filter (9) is inserted to prevent removing the powder when the vacuum is drawn. The insulation arrangement can take the form of a panel or a pipe, and the thin wall (3) can be mechanically deformed after the vacuum is drawn.
A method of thermally insulating the pressure containing side of high pressure vessels and pipes, comprising the steps of forming a sheath having spaced walls, filling the sheath with a powder insulating material comprising powder particles with open pores and irregular form, drawing a vacuum in said sheath through an opening in the sheath, heating said insulating material, sealing said opening while maintaining the vacuum, and irreversibly deforming the inside wall portion of the sheath after sealing the sheath to postcompress the insulating material, w...
