HEAT-INSULATING PRODUCT Russian patent published in 2012 - IPC F16L59/02 

FIELD: heating.

SUBSTANCE: heat-insulating product includes insulating elements of elongated shape, which are made from elastic-deformable fibrous material, connected to each other and enclosed in the cover that covers the side surfaces of elongated elements and consists of two flexible plates. One of the plates is tight and forms side surfaces of elongated elements, which are opposite to the surfaces facing the insulated object. The other plate forms the rest side surfaces of elongated elements. The product is equipped with additional tight cover made from polymer material. Tight cover is arranged on surfaces of elongated elements. Flexible plates are connected by means of a glued joint, and fibres of elastic-deformable fibrous material are oriented in an arbitrary way relative to side surfaces of elongated elements.

EFFECT: invention allows protecting the product not only against atmospheric and other outside moisture, but also against leaks of insulated medium, and arbitrary orientation fibres of fibrous insulators improves heat-insulating properties in complex sections of pipelines.
