Issues with the internal floating roof device to prevent the floating disk from rotating?
Thread Content
What are the advantages and disadvantages of the various common mechanical devices used to prevent the floating roof from rotating? How many sets should be installed, and are there any relevant standards? Please, dear seniors, give me some advice!
The most common and simplest option is two anti-rotation wires. Simple and lightweight, easy to install. Durable and robust.
Reply to 2# liugui1998: How is the anti-rotation feature of the guide post? I see that many old factories still use guide posts; is the strength of the steel wires guaranteed? How is the diameter of the steel wires determined? Are there any regulations? Could the elder brother explain it to me? I checked, and 50341-2003 doesn’t specify it!
It depends on the model of your floating roof. Nowadays, the floating roofs of internal floating roof tanks are all made of aluminum, and wire guides are commonly used; for external floating roofs, guide posts are used!
Reply to 4# Yifei Xiao: What we usually need to purchase are floating disk types; it hasn’t been decided yet whether to use tongue-type seals or bladder-type seals for sealing What standards are used to determine anti-rotation equipment?
The anti-rotation device doesn’t refer to just two wires; it also requires a buffering mechanism
Both aluminum and stainless steel floating pads use anti-rotation steel cables! Our unit uses both of these, and they seem to work quite well
It is best to use a tongue-type seal; bag-based tank cleaning is very troublesome, and residues often remain in the tank
