Product Details
Polyurethane jacket insulation pipeline
Polyurethane jacket insulation pipeline is a type of directly buried prefabricated insulation pipeline with good and reliable insulation performance and low engineering cost. Directly buried insulation pipes not only have advanced skills and useful performance that are difficult to compare with underground and overhead pipelines, but also have significant social and economic benefits, and are also a way to save energy in heating.
1. The use of black jacket insulation pipes is prone to damage during transportation and installation. After being buried, the depth from the ground is insufficient or the upper soil and road are relatively soft, resulting in damage caused by the rolling of heavy vehicles.
2. The treatment of the interface of the black jacket insulation pipe, during pipeline laying and installation, the two connected pipes are not welded tightly, resulting in water seepage, or damage caused by external sewage seeping into the insulation layer due to careless operation during the "patching" process.
Structure of polyurethane jacket insulation pipeline:
1. Polyurethane insulated steel pipe for operation: According to the technical requirements for transporting the medium, welded steel pipes, seamless steel pipes, and double-sided submerged arc spiral welded steel pipes are selected.
2. Polyurethane insulation steel pipe insulation layer: rigid polyurethane foam plastic is selected.
3. Polyurethane insulated steel pipe shell: choose high-density polymer or fiberglass.
4. Polyurethane insulated steel pipe leakage line: When manufacturing high-temperature prefabricated directly buried insulated pipes, wires are buried in the insulation layer near the steel pipe. Once a leakage occurs at a certain point in the pipeline, the transmission of the alarm line can display the accurate direction and degree of leakage on a dedicated detection instrument, so as to inform maintenance personnel to quickly handle the leaking pipe section and ensure the operation of the pipeline network.
The structural process of polyurethane insulation pipes:
1. Outer protective tube: The outer protective tube is mainly composed of polymer or fiberglass, in order to prevent corrosion of the insulation layer, and to support the working pipeline and accept external pressure to ensure the normal operation of the working pipeline.
2. Anticorrosive coating: The anti-corrosion coating has processes such as E anti-corrosion to ensure that the operating pipeline is not corroded and extend the service life of the pipeline.
3. Polyurethane foam layer: it can insulate the transportation medium and ensure the normal temperature of the outer surface of the protective tube.
4. Operation steel pipe: Ensure the normal flow of the transport medium.
