Steel sleeve steel insulation steel pipe manufacturer Guanghui customized

Description :

　　The vacuum layer of steel insulated pipes completely eliminates heat conduction and convection in the air layer, greatly reducing heat loss. Compared with the air layer structure, the outer wall temperature can be reduced by 8-13 ° C under the same insulation thickness. The vacuum pumping device completely solves the problem of the inner wall of the outer steel casing being easily corroded by hot and humid air, greatly improving the operating life of directly buried steam pipelines. The product lifespan has been extended to 30 years.. Steel insulated pipes with steel sleeves can be stably applied in different temperature environments, especially suitable for high-temperature steam pipeline projects. Steel insulated pipes with steel sleeves can effectively save space, have simple and convenient construction, and are widely used in heating insulation pipes, hot spring insulation pipes, heating insulation pipes, heating insulation pipes, air conditioning insulation pipes, steam insulation pipes, cold and hot insulation pipes, exterior wall insulation, and so on.

　　As the polyurethane rigid foam insulation layer is closely bonded to the outer skin of the steel pipe, the steel sheathed steel insulation pipe can isolate the infiltration of air and water and play a good anti-corrosion role. At the same time, its foam pores are all closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have good anti-corrosion, insulation, and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by external air and water. Steel sleeve steel insulation pipe high-temperature prefabricated buried insulation pipe is a type of directly buried prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost. Effectively solved the insulation, sliding lubrication, and waterproofing problems of prefabricated buried insulation pipes for high temperature heat transfer from 130 ℃ to 600 ℃ in urban centralized heating. High temperature prefabricated buried insulation pipes not only have advanced technology and practical performance that traditional trench and overhead pipelines cannot match, but also have significant social and economic benefits, and are powerful measures for heating energy conservation.

　　The moisture discharge pipe on the steel sleeve of the steel insulated pipe can not only timely discharge humid gases, but also serve as an alarm signal pipe for daily operation. The thermal compensation of the pipeline adopts a corrugated pipe compensator, which is installed inside the casing and made in a direct burial form, without the need for an observation well. The construction operation is convenient and the construction period is short. Suitable for transporting steam or other media below 2.5MPa and 350 degrees Celsius, this product uses steel pipes as the outer protective layer, which has the advantages of high strength, low damage, easy construction and maintenance, and long service life.

　　The steel sheathed steel steam insulation pipe is a combination of steel pipes. The pipeline anti-corrosion coating and ultra-fine glass wool are used to fill the space between the steel pipe and the outer pipe, or graphite, calcium silicate tile shell and polyurethane foam can be used. The embedding technology of steel shell (steel sleeve) is a new technology that is waterproof, anti-seepage, anti-seepage, pressure resistant, and fully sealed. This is a major breakthrough in the application of direct burial technology for high groundwater levels. The main issue with steel jacket steam insulation pipes is the reliability of sealing and waterproofing. In addition to good mechanical strength, the welding strength of the steel shell is high, and the reliability of waterproof sealing performance is also high. In addition, its high temperature resistance cannot be compared to other external protective tubes.

　　Steel sleeve steel insulated pipeline, steel sleeve steel steam insulated pipeline, steel sleeve steel insulated pipe, steel sleeve (steel sleeve steel) steam insulated steel pipe embedding technology is a new burial technology that is waterproof, leak proof, reverse osmosis, compression, and all enclosed. It is a direct burial technology that can cause greater damage in areas with high groundwater levels. It consists of ultra-fine glass and cotton filled steel pipes, anti-corrosion coated pipes, steel pipes, and outer pipes. It can also be made of graphite, calcium silicate tile shell and filled with polyurethane foam.
