Description

Direct-buried plastic-sheathed steel heat-insulation pipe with strong corrosion resistance

Technical Field

The application relates to the technical field of heat-insulating pipelines, in particular to a direct-buried plastic-sheathed steel heat-insulating pipe with strong corrosion resistance.

Background

The heat-insulating steel pipe is a steel pipeline which is processed by a heat-insulating process and ensures that the temperature in the working steel pipe and the surface temperature meet or meet the use requirements under the action of different working environments and external media, the steel-sheathed steel composite heat-insulating steel pipe is one of underground direct-buried pipelines, and an underground direct-buried mode can be carried out under the condition without a concrete structure, namely, the thermal expansion of the working steel pipe is carried out in the outer pipe, so that the material cost is reduced, the construction date is shortened, the safety of a heat supply pipeline is ensured, the heat-insulating steel pipe can be widely applied to different temperature environments more safely, and is particularly suitable for high-temperature steam pipeline projects. The use temperature can reach 150-450 ℃. The pipeline ports are generally sealed by polyethylene films or three-layer PE cold-wound tapes to prevent moisture or water from entering before installation or during construction. The multilayer staggered joint wrapping of the heat insulation material effectively reduces heat loss, and meanwhile, control measures are taken on the surface of the outer sleeve to prevent cold bridges from being generated, so that the temperature control of the outer sleeve anticorrosive layer is ensured. The heat insulation material is used for wrapping the multiple aluminum foil reflecting layers, so that the heat loss is effectively reduced, and the steam pipeline is more economical and reasonable.

Traditional plastic sheath steel insulating tube is long after using, and when the pipeline inside was used for transporting gas, atmospheric pressure was in great situation transportation for a long time under to lead to easily dashing not hard up with the connection between the insulating tube, chinese patent discloses: prefabricated insulating tube of formula of directly burying, patent application number: 201922227570.5, this patent "through being provided with down the blotter, the spring reaches the strong purpose of buffer capacity with last blotter, the blotter sets up four semi-ring parcel and lives the steel casing pipe down, produce great bulging force in the steel casing pipe, power can be buffered by two upper and lower blotters and spring rapidly and is decomposed, two upper and lower blotter structures are great most crucial, be a complete ring, it is strong to bear the impact resistance, the damage condition can not appear easily, nevertheless the relaxation phenomenon can appear in the spring after long-time the use of this equipment, and the cost is higher, the installation is also comparatively troublesome, consequently, need a direct-burried cover steel insulating tube that moulds that corrosion resisting property is strong now urgently.
