HEAT INSULATION METHOD FOR SLIDING SHUTTER Russian patent published in 2014 - IPC F16L59/16 F16K49/00 

FIELD: machine building.

SUBSTANCE: invention refers to heat insulation of main and process oil pipelines and oil product pipelines, namely, to the method of heat insulation of a sliding shutter. Heat insulation method for the sliding shutter involves design and manufacturing of a heat insulation structure from foam glass with a protective cover taking into account the geometric dimensions and peculiarities of the sliding shutter design; at that the heat insulation structure comprises two or more parts being connected by locks which provide for the access to the sliding shutter for maintenance and repair; the seams of the heat insulation structure are sealed by sealing gaskets from foamed rubber and the inner surface of a heat insulation product contacting with the sliding shutter is coated with antiabrasive material to protect its anticorrosion coating.

EFFECT: use of the proposed device provides for heat insulation of the sliding shutter with the usage of fire safe materials and for the access to it for its maintenance and repair.
