AI Technical Summary

⚠Technical Problem

Existing marine cage floating pipe connection technology suffers from problems such as limited angles, potential connection quality issues, complex processing, and long processing times, making it difficult to achieve optimal curvature transition in hydrodynamics and efficient installation.

⚗Method used

The floating pipe connection fittings are designed with a first rotary joint and a second rotary joint. Non-standard angle installation can be achieved through rotational connection. Combined with the composite pipe pin and connecting plate structure, the oblique cutting and welding of pipes are avoided, thereby improving installation efficiency and connection reliability.

🎯Benefits of technology

This has improved the angular flexibility and installation efficiency of floating pipe connections, reduced stress concentration, increased connection reliability and service life, and lowered manufacturing costs.
