Seals for Flammable Gases: Critical Barriers for Explosion Safety
In industries like petrochemicals, natural gas transport, hydrogen energy, and industrial gas systems, sealing flammable gases (methane, hydrogen, propane, etc.) is a matter of life and asset safety. Standard seals risk ignition via permeation, friction heat, or high-temperature failure. Flamma...Read more -
Replacing Metal Seals with Rubber Seals: Critical Considerations and Guidelines
Replacing metal seals with rubber seals is common in equipment maintenance or retrofits (e.g., to reduce costs, simplify installation, or adapt to specific media). However, the significant differences in physical and chemical properties between metal and rubber can lead to seal failure or ...Read more -
LNG Seals: Guardians of the Cryogenic Realm
In the LNG industry chain—spanning production, storage, transportation, and end-use—systems operate under extreme conditions: -162°C cryogenic temperatures, medium-to-high pressure, and flammable/explosive environments. Conventional seals fail catastrophically here, risking leaks. LNG-specifi...Read more -
PTFE Bellows: The Flexible Guardian in Demanding Chemical Environments
