Description

Technical Field

[0001] This utility model belongs to the field of flange technology, and specifically relates to a pipe connection flange. Background Technology

[0002] Aging or damage to gaskets can lead to leaks at pipe connections. Leaked media can pollute the environment. Regular inspection and replacement of gaskets, and even repair or replacement of leaking pipes, increase maintenance costs and downtime. These drawbacks primarily stem from the destructive effects of high pressure, high temperature, and vibration on gasket materials. High pressure can deform or even destroy gaskets; high temperatures accelerate oxidation and aging, reducing their elasticity and sealing performance; vibration can cause relative displacement between the gasket and flange contact surfaces, leading to seal failure.

[0003] Conventional solutions include selecting gasket materials resistant to high pressure, high temperature, and vibration, such as metal gaskets, graphite gaskets, or other special materials; and improving the gasket's structural design, such as using corrugated or multi-layered structures to enhance its sealing performance and vibration resistance. However, these methods also have drawbacks: gasket materials resistant to high pressure, high temperature, and vibration are expensive; improving gasket and flange structural and design costs increase manufacturing costs; increasing the gasket's preload may cause flange deformation or damage, or even stress concentration at the pipe connection, reducing its service life; and some special gasket materials may present challenges in processing and installation. Therefore, we aim to design a pipe connection flange with a novel structure to address these issues. Utility Model Content
