AI Technical Summary
Existing double-walled pipeline joints lack efficient thermal insulation and mechanical strength due to single-walled junctions, which are prone to mechanical fatigue and reduced lifespan, especially when using materials like polyurethane resin or DiPolyCyclopentadiene (DPCD) that undergo significant shrinkage and poor adhesion.
A double-walled pipeline fitting with segments in the form of half-shells, held by a fastening system, and a double-walled insulated sleeve, filled with a hardening material like DPCD or epoxy, ensuring reduced shrinkage and improved mechanical force transmission.
The fitting enhances mechanical efficiency and extends the pipeline's lifespan by minimizing shrinkage and maintaining thermal insulation, suitable for both J and S laying methods without additional equipment, and compatible with existing injection machines.
