Manufacture of Pipe-in-Pipe Assemblies - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240044440 titled 'Manufacture of Pipe-in-Pipe Assemblies
Simplified Explanation
The patent application describes a pipe-in-pipe assembly that includes an infill structure between inner and outer pipes. The infill structure is made up of elongate elements, some of which are reinforcing elements and others are insulating elements. The reinforcing elements have higher mechanical resistance to radial compression, while the insulating elements provide better thermal insulation. The reinforcing elements are positioned together within the infill structure to form reinforcing formations embedded between insulating regions defined by the insulating elements.
- The pipe-in-pipe assembly consists of an inner and outer pipe with an infill structure in between.
- The infill structure is made up of elongate elements, including reinforcing elements and insulating elements.
- The reinforcing elements have higher mechanical resistance to radial compression.
- The insulating elements provide better thermal insulation.
- The reinforcing elements are positioned together within the infill structure to form reinforcing formations.
- The reinforcing formations are embedded between insulating regions defined by the insulating elements.
Potential Applications:
- Oil and gas pipelines
- Subsea infrastructure
- Thermal insulation systems
Problems Solved:
- Provides improved mechanical resistance to radial compression.
- Enhances thermal insulation properties.
- Increases the structural integrity of pipe-in-pipe assemblies.
Benefits:
- Increased safety and reliability of pipelines.
- Improved energy efficiency by reducing heat loss.
- Enhanced durability and lifespan of pipe-in-pipe assemblies.
Original Abstract Submitted
a pipe-in-pipe assembly comprises a bundled infill structure occupying an annulus between inner and outer pipes () of the assembly. the infill structure is formed of a plurality of elongate elements laid along the inner pipe comprising a mixture of reinforcing elements (b) and insulating elements (a). the reinforcing elements have greater mechanical resistance than the insulating elements to radial compression whereas the insulating elements provide greater thermal insulation than the reinforcing elements. pluralities of the reinforcing elements are positioned together within the infill structure to form reinforcing formations, such as spacer formations, embedded between insulating regions of the infill structure that are defined by pluralities of the insulating elements.
