Abstract
The utility model relates to a pipeline, in particular to a composite anti-corrosion outer sleeve pipe for a steam direct burial thermal insulation pipe. The outer sleeve pipe for the steam direct burial thermal insulation pipe is divided into an inner layer, a middle layer and an outer layer, wherein the middle layer is arranged outside the inner layer, the outer layer covers the outer portion of the middle layer, the inner layer is a polyurea material layer, the middle layer is a chemical fabric layer, and the outer layer is an unsaturated polyester resin material layer. The outer sleeve pipe for the steam direct burial thermal insulation pipe improves the thermal insulation effect greatly reduces construction cost of insulation work due to the fact that the outer sleeve pipe for the steam direct burial thermal insulation pipe is novel and reasonable in structural design, is good in anti-corrosion performance, and is green and environment-friendly.
Description
Technical field
The utility model relates to a kind of pipeline, relates in particular to a kind of steamy thermal insulated direct-buried pipe outer sleeve of composite anti-corrosive.
Background technique
Bring in constant renewal in the selection of thermal insulation pipe on using thermal insulation material at present, be wrapped on the basis of playing insulation effect on the outer tube at materials such as felt, asbestos cloth or perlite suedes, new thermal insulation casing such as plastics PE, PVC, PPR overcoat and polyurethane heat-insulation sleeve pipe are arranged again, compound heat preservation sleeve pipe etc., but Corrosion Protection is not fine.
Summary of the invention
The utility model provides a kind of Corrosion Protection good steamy thermal insulated direct-buried pipe outer sleeve at above deficiency.
The technological scheme that the utility model adopted is:
A kind of steamy thermal insulated direct-buried pipe outer sleeve is divided into internal layer, mesosphere and skin, and the mesosphere is arranged on the internal layer outside, and skin is coated on the outside, mesosphere, and internal layer is the polyurea materials layer, and the mesosphere is the chemical fibre layer of cloth, and skin is the unsaturated polyester resin material layer.
Described skin, mesosphere and interior layer thickness are respectively 0.3mm, 0.2mm, 0.5mm.The utility model beneficial effect is:
Improved heat insulation effect, new reasonable because of this product structure design again, greatly reduced the construction cost of heat insulating work, the good and environmental protection of antiseptic property has been optimized environment and has been saved resource.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, internal layer, 2, the mesosphere, 3, skin.
Embodiment:
As shown in drawings, a kind of steamy thermal insulated direct-buried pipe outer sleeve is divided into internal layer 1, mesosphere 2 and outer 3, mesosphere 2 is arranged on internal layer 1 outside, and outer 3 are coated on 2 outsides, mesosphere, and internal layer 1 is the polyurea materials layer, mesosphere 2 is the chemical fibre layer of cloth, and outer 3 is the unsaturated polyester resin material layer.
Described outer 3, mesosphere 2 and internal layer 1 thickness are respectively 0.3mm, 0.2mm, 0.5mm.
