Buried steam insulation pipe, polyurethane spiral steel pipe, anti-corrosion insulation steel pipe manufacturer

Description :

　　Steam buried pipe manufacturers are mainly suitable for the transportation of non corrosive media such as hot water, steam, and cold water, with a temperature range of minus 10 ℃ to over 130 ℃. Galvanized iron sheet is stronger than polyethylene. Galvanized iron sheet will not age, rust, or corrode. The advantage of overhead galvanized iron sheet insulated steel pipes is that the iron sheet used to make the outer protective pipe adopts a galvanized anti-corrosion layer, which can be used in outdoor environments for a long time without corrosion; Due to the use of galvanized iron sheet instead of traditional polyethylene outer protective pipes, this product avoids the problem of polyethylene aging in outdoor environments for a long time; Introduction to the structural strength of the outer protective tube. The galvanized iron sheet outer protective tube adopts a spiral forming structure, which has good overall bending performance and good stress conditions at the joint joints. The following is a detailed introduction to the advantages of galvanized iron sheet:

　　1. Smooth appearance, beautiful and generous layout

　　2. Low installation cost, small installation space, and few connection points;

　　3. Good strength and rigidity;

　　4. Wide range of wall thickness options available;

　　5. Good corrosion resistance, suitable for various strong acid, alkali mist and other highly corrosive environments;

　　6. We can design and customize various specifications according to customer requirements;

　　7. Kang ultraviolet radiation has a service life of over 15 years for outdoor overhead use and up to 30 years for indoor use;

　　8. The product standardization process is high, and all components are produced in a standardized manner, saving materials, facilitating storage, and shortening delivery time;

　　9. The air duct processing adopts a continuous spiral bite structure, which has the advantages of good sealing, firm and non corrosive.

　　The material used for steam buried pipes is currently one of the most high-performance insulation materials internationally, which is twice that of extruded polystyrene board and more than three times that of polystyrene board. The characteristic of hard polyurethane is that it is rich and void free, which is a feature that many insulation materials cannot have. Hard polyurethane also has many excellent functions such as light weight, low thermal conductivity, good heat resistance, aging resistance, easy bonding with other substrates, and low solubility during combustion. It is widely used as insulation material for roofs, walls, ceilings, floors, doors, windows, and pipelines in many buildings. About 51% of building insulation materials are hard polyurethane materials, and this proportion is gradually increasing in China, now accounting for 15%.

　　Directly buried steam insulation pipes are mainly used in the centralized heating industry to transport hot water at 50-140 degrees Celsius. In some places in the south, it is used for centralized cooling industry. Divided into two types of hot and cold water for power, polyurethane insulated steel pipes are relatively affordable, so they are widely used. Another application, which is common, is long-distance transportation pipelines for oil. Due to its high viscosity, oil requires sufficient temperature to ensure circulation. Any medium with a temperature below 140 degrees Celsius that requires insulation can use this form of insulation. The working pipeline can be changed according to different media, and if there is a problem during installation, it will slide and shift. Below, we will teach you how to solve this problem from the polyurethane insulated steel pipe factory.

　　When the polyurethane insulated steel pipe with internal sliding and external fixation expands due to heat, there will definitely be some changes in its movement. Displacement is also possible, and both the insulation structure layer and the outer casing are integral structures. External fixation is best achieved by fixing the working pipe and the outer protective pipe together. Two large reinforced concrete supports should be installed at both ends of each section of the pipeline and compensator. This is beneficial for the fixation of the pipeline, as external fixation requires the installation of reinforced concrete supports, resulting in a large construction area and sometimes a long construction period. So it's better to pay attention before. Depending on the type of outer protective tube you want to use, it can be divided into plastic sleeve steel structure, fiberglass sleeve steel structure, and steel sleeve steel structure. Through practice, it has been proven that plastic sheathed steel structures are no longer suitable for the development trend of steam insulated pipelines.
