AI Technical Summary

Technical Problem

Existing oil and gas pipeline joint structures mostly use a single sealing gasket, which is difficult to adapt to the special medium characteristics of hydrogen. This results in insufficient reliability of the sealing structure, and hydrogen can easily seep and leak from the sealing gap, causing an explosion risk.

Method used

The hydrogen pipeline anti-corrosion sealing joint adopts the design of an inner stepped insertion groove, sealing ring and rubber elastic gasket, outer wall nano-modified polyurea coating and inner wall fusion bonded epoxy powder coating, combined with a clamping mechanism and explosion-proof solenoid valve, monitoring ring and early warning controller to achieve multi-layer sealing and anti-corrosion protection.

Benefits of technology

It significantly improves the fit and sealing performance of the sealing surface, effectively blocks the hydrogen permeation path, extends service life, reduces the risk of explosion, and provides timely monitoring and alarm for hydrogen leaks, thus providing time for emergency response.
