AI Technical Summary
Existing long-distance oil pipelines are prone to damage due to thermal expansion and contraction during seasonal temperature changes. Existing compensation devices have complex structures and cannot meet insulation requirements, and corrugated pipes are prone to wear and leakage.
An outer sleeve and an inner sleeve with a telescopic structure are set on the inner and outer sides of the corrugated pipe, and an aerogel insulation cotton layer is filled in between. Combined with guide grooves and limiting pins to prevent torsion, the structure is simplified and protection is provided.
It achieves efficient compensation of pipeline length, prevents corrugated pipe wear, reduces the impact of temperature changes, increases conveying speed, reduces leakage risk, and is suitable for underground and overhead operations.
