[Solved and can be closed] Issues regarding the design of the supports
Thread Content
This post was last edited by Lin Xuefeng on 2013-7-5 09:00. For devices that are not too tall (with a height of less than 5 meters), when designing the supports, it is necessary to decide whether to use channel steel or pipes as supports. Which option is better? Could someone with more experience provide a detailed explanation? lol
It depends on the diameter of the device as well as its load conditions, primarily the weight load; only by performing calculations can appropriate support components be selected.
Thank you. I mainly want to know, within the range permitted by the load constraints (since devices with high loads or high heights may require grouped seating), which type of support – one designed using channel steel or one designed using thick-walled pipes – has better strength. Do each of them have their own appropriate application areas? :handshake
Bro, are you talking about angle steel? I prefer to use angle steel – it fits well with the cylinder, making welding and assembly easier. The legs have the same inertial radius in all directions, which provides good stability against collapse.
I would like to ask under what circumstances 3 supports are used and under what circumstances 4 supports are used. Please advise, experts
This is mainly related to the diameter and the weight of the device itself; generally, for devices with a smaller diameter, three are sufficient.
Personally, I think it is better to use thick-walled pipes for withstanding loads, as steel pipes have better bending resistance than channel steel
The standards are fairly clear; if the load is too large, the standard methods cannot be used, so custom solutions are required, with calculations done on one’s own
Replying to #1: In my opinion (for equipment with a total height of 5000 mm or less, and leg heights of 1500 mm or less), both channel steel and round tubes can be used as legs; it depends on which is more convenient. Channel steel and angle steel are easier to weld to the cylinder, while round tubes require an arc-shaped groove to be created in order to be welded to the cylinder； Using round tubes results in greater solidity and better stability; it is recommended to use round tubes when the legs need to be relatively tall
