Description

Technical Field

[0001] The utility model relates to the technical field of pipeline production, and more specifically, particularly relates to an inner sliding guide bracket for a steam pipeline. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be conveyed by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. Steel-jacketed steel insulated pipe is one of the pipeline forms, which is mainly divided into seamless steel pipe, insulation layer and outer protective pipe. The insulation layer is located between the seamless steel pipe and the outer protective pipe.

[0003] The installation methods of steel jacketed insulated steel pipes are divided into: external sliding installation and internal sliding installation. In the external sliding installation, there are related external sliding guide brackets to support the seamless steel pipe wrapped with the insulation layer, and then the outer protective pipe is moved to cover the outside of the seamless steel pipe to provide external protection for the seamless steel pipe wrapped with the insulation layer. However, in the internal sliding installation, the seamless steel pipe wrapped with the insulation layer is directly pushed into the outer protective pipe without related auxiliary brackets. During the installation process, there is a risk of damage and displacement of the insulation layer.

[0004] Therefore, we propose an inner sliding guide bracket for a steam pipe to solve the above problems. Utility Model Content
