Coating and nano compound thermal-insulation tube sleeve

Abstract

The invention discloses a coating and nano compound thermal-insulation tube sleeve, which comprises two half shells which can be jointed together to form a complete tube sleeve body, wherein at least one thermal-insulation layer is arranged on each of the inner walls of the two haft shells; at the vertical joint position of the two half shells, the end face of the joint position of one of the half shells is a longitudinal waterproof convex rib, the end face of the joint position of the other half shell is a longitudinal waterproof recess matched with the longitudinal waterproof convex rib, and the longitudinal waterproof convex rib and the longitudinal waterproof recess are connected in an embedding way; a fireproof coating layer is coated on each of the inner wall surfaces of the two half shells in the at least one thermal-insulation layer; and the thermal-insulation layer is a nano flexible thermal-insulation layer of which the outside is adhered to the shell by a mesh fabric. The coating and nano compound thermal-insulation tube sleeve has the characteristics that: the structure is simple; use is convenient and reliable; a certain sealing effect can be achieved; water inflow is prevented; the service life of the tube sleeve is prolonged; the thermal-insulation effect of the tube sleeve is strengthened; the use cost of the tube sleeve is reduced; daily maintenance is convenient; and the like.

Description

technical field [0001] The invention relates to a casing specially used for pipe protection and heat preservation outside the connection pipe, especially a pipe sleeve with composite heat preservation. Background technique [0002] Existing connecting pipes are mainly used in fluid transmission pipes such as thermal pipes and oil products. They are basically exposed to the sun and rain, and some of them are used in extremely harsh environments, which may easily lead to pipe cracks and damages, reducing the quality of the pipes. The service life of the pipe; and for the heat pipe, it will lose a lot of heat and the energy loss is serious. Therefore, many connecting pipes will use the pipe cover at present. This kind of pipe cover is originally painted on the outer wall of the connecting pipe.

[0002] Existing connecting pipes are mainly used in fluid transmission pipes such as thermal pipes and oil products. They are basically exposed to the sun and rain, and some of them are used in extremely harsh environments, which may easily lead to pipe cracks and damages, reducing the quality of the pipes. The service life of the pipe; and for the heat pipe, it will lose a lot of heat and the energy loss is serious. Therefore, many connecting pipes will use the pipe cover at present. This kind of pipe cover is originally painted on the outer wall of the connecting pipe. Put on a protective layer, this protective layer includes a protective layer with thermal insulation effect, but once this protective layer is painted on the pipe wall, it is difficult to remove, even if it is forcibly removed, it will be destroyed once sex demolition

So now there is a prefabricated detachable pipe sleeve cover that can be installed directly on site. This detachable pipe sleeve cover is made up of at least two halves of the pipe sleeve. , if there are buckles or flanges for mutual connection installed at the joint of the two half-pipe sleeves, at least parts similar to fasteners should be used at the joint of the two half-pipe sleeves, such as the buckles, etc. to connect them Connection, because after the actual splicing, there are certain splicing gaps at the splicing place, these gaps will bring leaks to the entire pipe sleeve casing, and it is easy for rainwater to easily immerse into the inside of the pipe sleeve casing

Therefore, the pipe sleeve casings seen in the market are not only unattractive in appearance, easily deformed, and reduce the service life and use effect of the pipe sleeve casings, but also only rely on conventional insulation material layers for insulation, and the insulation effect is not ideal.
