The main business of Xinyu innovation service company is: seamless polyurethane insulation steel pipe, polyurethane insulation spiral steel pipe, black jacket polyurethane insulation steel pipe, polyurethane foam insulation pipe, polyurethane directly buried pipe insulation, steel sleeve steel directly buried thermal insulation steel pipe, steel sleeve steel steam insulation steel pipe, complete specifications, welcome to discuss Manager Jia. Polyurethane insulated steel pipe is mainly used to transport hot water, steam and other gases or liquids that need thermal insulation. Because there is a layer of insulation cotton in the middle, it can greatly reduce the heat loss in the transportation process, and the outer skin can also be used for corrosion prevention, so as to improve the service life of the pipeline. At present, it has been widely used in the pipeline network of liquid and gas, Chemical pipeline insulation engineering petroleum, chemical, central heating network, air conditioning and ventilation pipeline, municipal engineering, etc. The new innovative service of polyurethane foam insulation steel pipe for direct buried heating reduces the construction period. The pipeline can be filled directly after installation without any measures, which is also the advantage of value insulation pipe. With the continuous improvement of polyurethane insulation steel pipe production technology, the continuous improvement of equipment. At present, polyurethane insulation steel pipe is not only used as thermal pipe. At present, many domestic professional design institutes and manufacturers are using advanced technology to constantly update the appearance and performance of insulation pipes. Of course, market competition is inevitable. There are many kinds of polyurethane insulation pipes. Let's learn about the advantages of polyurethane directly buried thermal insulation pipes: Polyurethane directly buried thermal insulation pipes are used in heating (cooling) projects, and their thermal insulation and sealing effect is remarkable. When they are used for buried laying, they can not only save energy, reduce costs, but also beautify the environment. Advantages of polyurethane directly buried insulation pipe: Polyurethane directly buried insulation pipe has the advantages of high-efficiency thermal insulation, waterproof, anti-corrosion, thermal insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, light capacity, high strength, simple and fast construction, and not afraid of plant root thorn.

Polyurethane foam heat preservation steel pipe for directly buried heating

1、 Advantages of polyurethane insulation directly buried pipe

1. It is suitable for underground and humid environment, and can withstand high temperature and extremely low temperature.

2. Strong anti-interference ability. If polyurethane insulation directly buried pipe is used as cable sleeve, it can effectively shield external signal interference.

3. It has good pressure strength and the pressure can reach 6Mpa.

4. The insulation performance is good, as the protection tube of electric wire, the leakage will never happen.

5. No thorn, smooth pipe wall, suitable for wire or cable during construction.

However, after more than 30 years of efforts, especially after nearly 10 years of rapid development, many products have grown from scratch, from single to diversified, from low quality to high quality, and their application is more and more common. Polyurethane is a kind of thermal insulation material commonly used in the world. Rigid polyurethane has many excellent properties and is widely used in thermal insulation field in Europe and America. About 49% of thermal insulation materials in developed countries such as Europe and America are polyurethane materials, while in China, the proportion is less than 20%. Therefore, there is still a lot of room for the development of polyurethane insulation steel pipe in China. The main technology of composite silicate refers to the marking: This product * *, harmless, non polluted steel sleeve steel directly buried steam insulation steel pipe, one is made of super fine glass wool which is filled with steel pipes, anticorrosive coat pipes and pipes filled with steel pipes and outer steel pipes. It can also be made of graphite, calcium silicate tiles and polyurethane foam. The embedding technology of steel casing (steel sleeve) is a new embedding technology with waterproof, leakage proof, impermeability, compression resistance and full sealing.

2、 Application of polyurethane foam insulation steel pipe for direct buried heating

1. Various forms of circulating water system (Civil circulating water and industrial circulating water) have excellent performance and the anticorrosion life can reach 50 years.

2. Fire water supply system.

3. Water supply and drainage transportation of each building (especially suitable for the cold and hot water systems of hotels, hotels and * * residential areas).

4. Transportation of various chemical fluids (resistant to corrosion of acid, alkali and salt).

5. Buried pipes and crossing pipes of wires and cables.

Polyurethane foam thermal insulation steel pipe for direct buried heating Xinyu innovative service is often used in the central heating system of urban residential quarters, and the water temperature generally does not exceed 120 ℃. Therefore, two methods are adopted, i.e. compensating direct burying method and non compensating direct burying method. Let's take a look at * types of direct buried laying of compensation. In construction, compensators are required to be used for this purpose Part of the total compensation deformation of section pipeline is generally applicable to the working environment below 120 ℃ and the working pressure is less than 1.6Mpa; the second type of direct buried laying without compensation uses the resistance between soil and external pipe to fix the pipeline, without additional use of compensator and fixed support tools, so the construction is very convenient. Standard for polyurethane foam insulation pipeline - detection of polyurethane insulation pipes for in-situ placement of polyurethane precast pipes: 1. introduction of polyurethane insulation pipe, that is, rigid polyurethane foam plastic insulation pipe for thermal insulation materials, rigid polyurethane foam, needless to say, its basic structure consists of internal media pipes, intermediate rigid polyurethane foam insulation layer, external protective layer. Composed of.
