Abstract:

Based on a deep-sea long-distance pipeline solid transmission device project, combined with the deep-sea long-distance solid transmission device tube structure, characteristics, manufacturing technology and working conditions,the paper analyzes and compares the advantages and disadvantages of corrosion resistance between different structures,and provides solutions for the subsequent design of deep-sea pipelines and narrow-long inner-bore tubes.

Key words:deep-sea remote pipeline,solid transmission,long and narrow bore,anti-corrosion
