Solution Overview
Problem
The existing fixed-point pipe supports for low-temperature pipelines are complex and costly to install and remove, requiring pipeline shutdowns, pressure testing, and potential destruction of thermal insulation due to moisture infiltration, which complicates the assembly process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fixed-point pipe support is installed using conventional methods (injected or prefabricated components), then the thermal insulation is properly positioned and fixed, but the installation process is complex and requires pipeline shutdowns, pressure testing, and potential destruction of thermal insulation
Solution Approach 1:
The fixed-point pipe support is divided into multiple separable components: an outer shell that can be opened radially, an insulating system, and a supportable pipeline portion. This segmentation allows the support to be installed by opening the outer shell radially, positioning the pipeline, and closing the shell, eliminating the need for complex injection processes or pipeline shutdowns while maintaining proper thermal insulation positioning
Solution Approach 2:
The outer shell is designed with a division plane extending perpendicularly to the cross-sectional plane, enabling radial opening and closing motion. This dimensional change from axial to radial operation allows installation without pipeline shutdowns and simplifies the installation process while ensuring reliable thermal insulation positioning
2Ease of repair
If the fixed-point pipe support is removed and replaced using conventional methods, then the defective support can be replaced, but the procedure is complicated and expensive requiring cutting out the support, welding, and renewed pressure testing
Solution Approach 1:
The separable design with radial division plane allows the outer shell to be opened and the support to be removed without cutting or welding. The support can be replaced by simply opening the shell, removing the old support, installing a new one, and closing the shell, dramatically reducing replacement time and eliminating the need for pressure testing
Solution Approach 2:
The outer shell transitions from a static fixed structure to a dynamic openable/closable structure with radial motion capability. This dynamic design enables quick removal and replacement of the support without permanent installation, reducing both replacement time and complexity while maintaining support reliability
3Reliability
If moisture penetrates into the insulating system of low-temperature pipelines, then the moisture freezes and destroys the insulating system, but conventional installation methods increase the risk of moisture infiltration during installation and removal
Solution Approach 1:
The radial segmentation allows the outer shell to be opened without compromising the sealed environment of the insulating system. The support can be accessed and replaced without exposing the insulating system to moisture, maintaining integrity while enabling easy operation
Solution Approach 2:
The outer shell acts as an intermediary protective barrier that can be opened and closed to access the insulating system without exposing it to the external environment. This mediator allows easy installation and removal operations while preventing moisture infiltration that would destroy the insulating system

AI summary
The invention relates to a cold-insulated fixed-point pipe support for a low-temperature pipeline which includes an insulating system arranged between an outer shell and a supportable low-temperature pipeline having solid thermal insulating material which thermally insulates the pipeline from the low-temperature environment. A rotation-preventing and displacement-preventing device prevents rotation and displacement of the thermal insulating material with respect to the pipeline and an outer shell. A fixed-point pipe support is adapted to be fitted and removed in a substantially radial direction over the pipeline, and has at least one division with respect to shape with a division plane thereof extending perpendicular to a cross-sectional plane, and having a connecting device for releasable connecting and fixing shaped parts formed by the division.
