Jiangsu Thermal Polyurethane Foam Insulation Steel Pipe Large Diameter Composite Insulation Pipe Customizable

Description :

　　The insulation pipe is composed of an inner working steel pipe, polyurethane, glass wool insulation layer, polyethylene or steel pipe as the outer protective pipe. Its characteristics include: high temperature resistant insulation layer, lubrication layer, and elastic sealing element. This utility model effectively solves the insulation, sliding lubrication, and waterproofing problems of prefabricated buried insulation pipes for high temperature heat transfer in urban centralized heating at 130 ℃ -800 ℃. Insulated pipes are widely used in the transportation network of liquids and gases, chemical pipeline insulation engineering, petroleum, chemical, centralized supply, central air conditioning ventilation pipelines, municipal engineering, etc. High temperature prefabricated direct buried insulation pipe is a type of direct buried prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost. Effectively solved the insulation, sliding lubrication, and waterproofing problems of prefabricated buried insulation pipes for high temperature heat transfer in urban centralized heating from 80 ℃ to 150 ℃.

　　Insulated steel pipes are an important factor affecting energy conservation, and the development and application of insulated steel pipes are receiving increasing attention from countries around the world. After the 1970s, foreign countries generally attached great importance to the production and application of insulated steel pipes, striving to significantly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The insulation industry abroad has a long history, and new insulation materials are constantly emerging. Before 1980, the development of insulation steel pipes in China was very slow, and the few insulation factories could only produce a small amount of underground buried insulation steel pipes. However, after more than 30 years of effort, especially after nearly 10 years of rapid development, many products in China's insulation industry have gone from scratch, from single to diversified, from low to high quality, and their applications have become increasingly common. Polyurethane material is the most commonly used insulation material internationally. Rigid polyurethane has many excellent properties and is widely used in the field of thermal insulation in European and American countries. About 49% of insulation materials in developed countries such as Europe and America are polyurethane materials, while in China, this proportion is less than 20%. Therefore, there is still a lot of room for the development of polyurethane insulated steel pipes in China.

　　The progress of polyurethane foaming and thermal insulation technology The progress of polyurethane foaming and thermal insulation technology I, the principle of polyurethane on-site foaming construction process: the principle of polyurethane foam spraying and pouring process is that the polymerization reaction of polyether isocyanate can generate amino jia ester, that is, it can generate the required poly jia ester, also known as polyurethane foam. In the reaction process, catalyst, crosslinking agent, foaming agent, foam stabilizer, etc. are added at the same time to promote and improve the chemical reaction. These raw materials are divided into two groups. After being fully mixed, they are respectively pumped into the metering pump in proportion. They are fully mixed and sprayed on the surface of the pipeline or equipment in the spraying or pouring mixer, where reaction occurs. They bubble within 5 to 10s to generate foamed plastics, which are solidified and shaped.
