High-efficiency spring-loaded large-compensation seal for fully liquid-contacted honeycomb floating disks in internal floating roofs
Thread Content
May I ask: What is the structural type of the high-efficiency spring-loaded large-compensation seal used in full-liquid-contact honeycomb floating disks for internal floating roofs?
How should cellular floating discs be classified? Should they be classified as fusible floating discs?
According to the relevant provisions on internal floating roofs in the latest version of GB50160, float-type floating pans and honeycomb floating pans, whether made of aluminum alloy or stainless steel, are classified as fusible metals.
The large-compensation hermetic seal consists of a metal sealing plate, an evaporation-proof diaphragm, a spring pressure plate, a support plate and strip, connecting bolts, etc. The advantage is its ability to accommodate larger floating disc offsets, while the disadvantage is that it is not suitable for use with inner floating discs of small diameter.
Stainless steel with a thickness of less than 3 mm is easy to melt
