High temperature prefabricated buried insulation pipes produced outside of China are equipped with leakage alarm lines. Once a leakage occurs in a certain part of the pipeline, the accurate location and degree of leakage of the insulation pipe can be displayed on the detection instrument through the transmission of the alarm line. Hot pressed perlite, silicon bead insulation materials, composite silicates, polyurethane foam, etc. require detailed selection in both insulation pipe structure and insulation materials. In the field of steam pipeline development and application, China is not inferior to developed countries. The medium conveyed by steel insulated steel pipes is generally used in steam thermal power plants, and there is no specified length of service life in the standard. In order to notify the leak detection personnel to quickly handle the leaking pipe section and ensure the safe operation of the heating pipeline network. After the contraction is completed, check again whether there are any curled edges and bubbles in the heat shrink tape and cover. If there are, repair and eliminate bubbles in a timely manner to ensure that the heat shrink tape and cover are flat. The Qiang tube of the high-pressure foaming machine injects foaming solution into the cavity between the outer protective layer and the steel pipe, and the foaming solution immediately foams to form an insulation layer. The present invention increases the adhesion between the outer protective layer and the insulation layer by adding corona treatment and intermediate frequency heating treatment, ensuring uniform forming density of the insulation layer and achieving a tight structure of the insulation pipe.

The insulation pipe processing is parallel to the on-site ditch, and only on-site joints can shorten the construction period by more than 50%. In the pipe network construction, selecting a good manufacturer can ensure the quality of polyurethane foam insulation pipe, and the laying of the next pipe is also very important, so it is not careless at all. How to ensure the construction quality of polyurethane foam insulation pipes? The following points are believed to be helpful to you. Firstly, an important point is the nature of the construction process. Only by ensuring construction can subsequent pipeline construction be carried out. The construction manager must manage and control the construction site. Before construction, personnel must conduct on-site inspections of the construction area, select the pipeline network routes, and make corresponding construction drawings to ensure the standardization and normalization of the construction project. The welding of pipelines is of utmost importance in construction, and it is necessary to find qualified construction units. Ensure the standardization of welding and reduce the probability of leakage during pipeline use. Construction should be carried out according to the drawing standards.
