What is the market prospect of hot water insulation pipe?

With the development of the whole industry chain of insulation pipes, a number of insulation materials have now ranked among the forefront of the insulation industry. The production of organic, inorganic and metal insulation materials has long been well received by the industry and consumers. The rock wool insulation pipes produced are generally non-combustible insulation materials.

Insulation pipes are divided according to the use temperature of insulation materials, and most of the situations are: high-temperature resistant (more than 500) directly buried insulation pipes, medium-temperature resistant (100 500) directly buried insulation pipes, normal temperature (0 100) polyurethane insulation pipes, and low-temperature resistant (-30 0 use), ultra-low temperature (-30 below) cold insulation materials. According to the structure of the insulation material, the insulation pipe is divided into:

Fiber (solid matrix, continuous pores), porous (solid matrix continuous, porous discontinuous), powder (solid matrix discontinuous, stomatal continuous) insulation materials. One-time compensation for direct burial laying of insulation pipe.

The working principle of polyurethane directly buried insulation pipe is that the welded pipe needs to be removed to locate the angle steel, and the pipe is heated to within the temperature range value that we can carry out, the pipeline is thermally elongated, and the corrugated expansion joint compensator will be compressed accordingly. In the work, it is compensated by the tensile variant of the pipe. After trying this method, the compensator compensates for the deformation that this section of pipeline produces under the design temperature difference, and thus the balance point of tension and compression in the pipeline work can be in the most suitable position of the total deformation under the design temperature difference.

In addition to the direct buried insulation pipe produced outside China, are provided with leakage alarm line, once the pipeline leaks somewhere, through the conduction of the alarm line, can show the accurate position of the water seepage of the insulation pipeline, the leakage and the size of the leakage degree on the special detection instrument, so as to notify the seepage inspector to quickly deal with the leaking pipe section, ensure the safe operation of the heating pipe network. At present, the domestic production of insulation pipes is equipped with leakage alarm lines, which need to be filled.

In short, the insulation pipe not only has the advanced technology and practical performance that is difficult to be compared with the traditional trench and overhead laying pipeline, but also has significant social and economic benefits, and is also a powerful measure for heating and energy saving. The use of direct buried heating pipeline technology marks that the development of China's heating pipeline technology has entered a new starting point. With the further improvement and development of this advanced technology, it is imperative to replace trenches and overheads with direct burial of heating pipes.

I do too much, and the price is very low.

1.First of all, we must determine the scope of our use, polyurethane insulation pipes are widely used in urban heating pipelines, chemical industry, cooling, heating and other fields. 2.

Looking at the characteristics of polyurethane insulation pipes, whether it is prefabricated polyurethane insulation pipes, polyurethane directly buried insulation pipes or other production processes, the process is different, and the first will be very different. Pin 3Looking at the strength of polyurethane insulation pipe manufacturers and the quality of products, there is a big difference between large manufacturers and small manufacturers.

4.Look at the model of the polyurethane insulation pipe, as well as the thickness of the pipe, these also determine the number of polyurethane insulation pipes. 5.

The common calculation method of polyurethane insulation pipe** is: (outer diameter of steel pipe + thickness of insulation layer) * thickness of insulation layer * cubic number per meter. The number of cubic meters per meter is multiplied by the ** per cubic meter is the unit price per meter of directly buried prefabricated polyurethane insulation pipe.

6.The best is to find a professional polyurethane insulation pipe manufacturer to inquire, Wanfu polyurethane insulation pipe manufacturers, focusing on the polyurethane insulation pipe industry for 20 years, because professional, so trust!
