The warm steel pipe refers to a steel pipe that is processed and processed by a heat preservation process and that ensures the temperature and surface temperature of the working steel pipe to meet or meet the requirements of use under different working environments and external media. So, do you know what the insulation pipe classification is? Today I introduced to you the classification of thermal insulation pipes and other related content. We also hope that through the following introduction, we can understand the knowledge of the insulation pipe in-depth and understand it, and at the same time it is convenient for everyone to choose to purchase.
Insulation pipe introduction
Insulating steel pipe refers to a steel pipe that is processed and processed by a heat preservation process, and that ensures the temperature and surface temperature of the working steel pipe to meet or meet the requirements of use under different working environments and external media.
Insulation pipe advantages
Insulated steel pipe is a steel pipe that can meet the requirements of internal temperature and surface temperature. It is processed through the heat preservation process. The advantages of the heat-insulating steel pipe are strong and durable, not easily damaged and eroded, reduced heat loss, good sealing performance, good effect on waterproof and heat insulation, convenient construction, low cost, and good insulation performance.
Insulation pipe material
According to the pipe material (steel), the steel pipe can be divided into: carbon pipe and alloy pipe, stainless steel pipe and so on. Carbon tubes can be divided into ordinary carbon steel tubes and high-quality carbon structural tubes. Alloy tube can be divided into low alloy tube, alloy structure tube, high alloy tube, high strength tube. Bearing tube, heat-resistant acid-resistant stainless tube, precision alloy (such as Kovar) tube and high-temperature alloy tube.
Insulation pipe classification
1. Steel jacket steel composite thermal insulation steel pipe
Introduced for everyone is the specific classification of insulation pipe. First of all, we are talking about steel-clad steel composite heat-insulated pipes. It is a kind of pipeline that can be buried in the ground. It can be used without concrete, so that we can reduce the cost of materials when it is used. At the same time, we can also shorten the time we spend on construction. Steel-clad steel composite heat-insulating steel pipes can be classified into inner-sliding type and outer-sliding type according to different sliding forms of heat-preserving structures.
The internal sliding type is mainly composed of a steel pipe, a jacket pipe, a composite silicate or a microporous calcium silicate, which can be used to transport a medium, a rigid polyurethane foam and an anticorrosive protective layer of a glass fiber reinforced plastic shell, and the like. This kind of inner slide type heat-insulating steel pipe is very reliable in some heat-treating technology. This is mainly because of its heat-preservation structure consisting of drag reduction layer, heat insulation layer, jacket steel pipe, exterior coating layer, aluminum foil reflection layer and so on.
The structure of the external sliding type heat-insulating pipe is mainly composed of inner steel pipe, zinc-rich primer, sliding guide bracket, high-temperature resistant glass wool, jacketed steel pipe, air insulation layer, aluminum foil reflective layer, and jacket steel pipe anti-corrosion layer.
2, polyurethane insulation pipe
Next, we introduce the polyurethane insulation pipe, its advantages are: use it to reduce the project cost; polyurethane insulation pipe its low heat loss, which guarantees that it can save energy; the third advantage is its Corrosion resistance is better, insulation is also better, in addition to its long service life.
Insulation pipe application
Insulated steel pipe, it is more suitable for use in -50 °C -150 °C temperature, while its application is also more extensive, it can be applied to central heating, centralized cooling, cold storage, coal mines, or petrochemical industries.
Insulation pipe quotation
The price of thermal insulation steel pipe is mainly affected by factors such as its brand, manufacturer and size. In addition, the quality of the thermal insulation steel pipe, the quantity of the thermal insulation steel pipe, the seller and the time point will influence the price of the thermal insulation steel pipe to a certain extent.

Development Status of China Insulation Pipes
Insulating steel pipe is an important factor influencing energy saving. The research and application of heat-insulating steel pipe is increasingly valued by all countries in the world. After the 1970s, foreign countries generally paid attention to the production and application of insulated steel pipes, and strived to significantly reduce the energy consumption, thereby reducing environmental pollution and greenhouse effect. Foreign insulation industry has a long history, and new insulation materials are also emerging. Before 1980, the development of thermal insulation pipes in China was very slow. A few thermal insulation plants can only produce a small amount of underground direct-buried insulated steel pipes. However, after more than 30 years of efforts, China's thermal insulation industry has witnessed rapid development, especially after nearly 10 years. Products from scratch, from singleness to diversification, quality from low to high, the application is more and more common. Polyurethane material is currently the most commonly used insulation material in the world. Rigid polyurethane has many excellent properties and is widely used in thermal insulation in Europe and the United States. About 49% of the insulation materials in Europe and the United States and other developed countries are polyurethane materials, while in China this proportion is still less than 20%. Therefore, there is still much room for the development of polyurethane insulation pipe in China.

Description:It is braided with high purity PTFE (Teflon) filament. PTFE material has a low friction and excellent resistance to chemicals. PTFE Braided Packing is resilient, chemical resistant, self-lubricating, and withstand high linear speed and pressure with minimum wearing to the shaft. Ptfe Packing can be used in various pumps and valves. It is especially good for corrosive media, high speed application, or applications that require clean and minimum contamination material.
Packings made from PTFE are a mainstay of the mechanical compression packing industry. PTFE is well known for its outstanding resistance to chemical attack, low coefficient of friction and wide temperature tolerance including cryogenic service. This wide flexibility makes PTFE packings a popular choice for those difficult applications where strong solvents, corrosive chemicals and oxidising media require to be sealed. Style options:
