Analysis Of The Relationship Between Epoxy Resin Sleeve Design Concept And Pipeline Pressure Rating

As a composite material component used for lining, repairing, or protecting existing pipelines, epoxy bushing for transformer's design logic primarily revolves around material properties, site conditions, and engineering functions. The resin material itself exhibits high rigidity and significant inelasticity after curing, unlike traditional steel or PE pipes which require predictable pressure-strain relationships. The mechanical response of composite materials is typically based on complex stress analysis and actual field load conditions, rather than a single PN rating setting.
