Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Examples

As shown in fig. 1, the outer heat preservation pipe special for petrochemical equipment is used for heat preservation of a pipeline of the petrochemical equipment and sequentially comprises a filling bag layer 1, a first heat preservation layer 2, a bubble film layer 3, a second heat preservation layer 4 and a reflection film layer 5 from inside to outside, and the layers are connected through an adhesive. The thickness of bubble rete can be set for as required, and the bubble membrane is bubble paper, has certain heat preservation, antidetonation effect, and what general bubble membrane internal packing was the air, the utility model discloses in, bubble membrane internal packing carbon dioxide, when meeting with the naked light, the bubble of bubble membrane is destroyed, releases carbon dioxide to play better flame retardant efficiency.

The filling bag layer is a cylindrical bag which is attached to the inner wall of the first heat-insulating layer and is provided with a fillable inner cavity, and a petrochemical equipment pipeline penetrates through the middle of the filling bag layer; the bag is provided with a valve 6.

The valve 6 is arranged in the middle of the filling bag layer and is exposed after penetrating through the first heat-insulating layer, the bubble film layer, the second heat-insulating layer and the reflection film layer.

The filling bag layer can be filled with a filling 101 such as gas or water. Generally, the filling bag layer is filled with water or air, so that a certain heat preservation and insulation effect can be achieved, particularly, the air is used as a filler, the use amount of materials such as heat preservation cotton can be greatly reduced while the thickness of the heat preservation layer is ensured, and the cost is saved; in the area with large environmental temperature change, water with large specific heat capacity can be preferentially used as the filler.

The adhesive is an inorganic adhesive. Inorganic adhesives generally have better fire ratings than organic adhesives.

The first heat-insulating layer, the bubble film layer and the second heat-insulating layer are made of fireproof materials above B1 level.

The reflecting film layer is preferably made of aluminum foil.

The using method comprises the following steps: sleeving the external heat insulation pipe special for the petrochemical equipment on the outer side of the pipeline of the petrochemical equipment, and injecting air or water into the filling bag layer through a valve to enable the filling bag layer to expand to be in contact with the outer wall of the pipeline of the petrochemical equipment so as to be fixed on the pipeline of the petrochemical equipment; the thickness of the filling bag layer has certain variability, so that the filling bag layer has good adaptability to petrochemical equipment pipelines with different outer diameters (such as the outer diameter range of 10-20 cm), and is beneficial to reducing the construction cost and improving the construction efficiency.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
