Description

Pipeline heat preservation shell

Technical Field

The utility model relates to a pipeline field, concretely relates to pipeline heat preservation shell.

Background

Since the advent of polyurethane synthetic materials in the thirty years, polyurethane insulation pipe shells have been developed rapidly as an excellent heat insulation material, and have become more and more extensive in application range, and are also widely used in various pipelines for heating, refrigeration, oil transportation, steam transportation and the like due to simple construction and remarkable energy-saving and corrosion-resistant effects. It is used for various pipelines for heating, refrigerating, oil and gas transportation.

The insulating layer-polyurethane foaming is coated outside the anticorrosive layer of the steel pipe by using methods such as in-situ tank pouring or prefabricating and forming, and the method is simple and convenient and has quick working efficiency. The heat conductivity coefficient is small: the thermal conductivity of the polyurethane insulating shell is the lowest in the insulating material, so that the heat loss of the material can be reduced to the minimum. Because the closed porosity of the polyurethane foam reaches more than 92 percent, the polyurethane foam is used as the heat-insulating layer of the directly buried pipeline, not only can play a role in heat insulation, but also can effectively prevent water, moisture and other corrosive liquids and gases from permeating, and prevent the breeding and development of microorganisms. The polyurethane foam can be firmly bonded with various materials, so that the problem that an anticorrosive layer is bonded with the polyurethane foam as the insulating layer of the directly buried pipe is hardly considered. The polyurethane heat-insulating layer has an adaptive temperature of + 120-196 ℃ and can reach +190 ℃ in a short time (more than ten hours). If the user needs to be at 190 ℃ for a long time, the high-temperature material can be used for molding according to the user needs. The polyurethane thermal insulation pipe shell is used for heat preservation and cold insulation of indoor and outdoor pipelines, central air-conditioning pipelines, chemical industry, medicine and other industrial pipelines. The high-performance polyether polyol and the polymetaphylpolyphenyl polyisocyanate are used as main raw materials and are foamed through chemical reaction under the action of a catalyst, a foaming agent, a surfactant and the like. The polyurethane pipe shell has the excellent characteristics of light capacity, high strength, heat insulation, sound insulation, flame retardance, cold resistance, corrosion resistance, no water absorption, simplicity and rapidness in construction and the like, and becomes an indispensable material for heat insulation, water resistance, leakage stoppage, sealing and the like in industrial departments such as buildings, transportation, petroleum, chemical industry, electric power, refrigeration and the like. Polyurethane rigid foam tile (pipe): the heat-insulating and cold-insulating material is used for heat insulation and cold insulation of indoor and outdoor pipelines, central air-conditioning pipelines, chemical industry and medicine industrial pipelines and the like. The polyurethane rigid foam direct-buried pipe is used for central heating pipelines and various refrigeration and industrial pipelines.

The pipeline is insulated, and the condensation or freezing of a pipeline conveying medium is avoided.
