May I ask who here has the lifting lug materials for chemical tower equipment?
Thread Content
Hello everyone. I am a equipment design technician at a manufacturer of PVC/FRP chemical tower equipment. Our factory mainly produces chlor-alkali equipment, such as chlorine scrubbers, packed dryers, and bubble tray towers; the weight of these towers generally ranges from 1 to 10 tons. Dear friends on this forum, do you have any information regarding the structural design of lifting lugs and load-bearing calculations? Could you please share it with me for reference? Those who are knowledgeable in this area are welcome to reply and discuss it with me. Thank you all!
http://bbs.hcbbs.com/redirect.php?tid=272879&goto=lastpost The poster can take a look here; HG/T 21574-2008 – Technical requirements for lifting lugs and related engineering aspects – contains most of the information you need! ! ! !
The lugs material specified in the standard HG/T 21574-2008 is basically Q235-A
Lugs are non-compressive elements, and using Q235-A is perfectly fine – it offers good cost performance.
Refer to the standard for lifting lugs, HG/T 21574-2008; this latest standard is quite comprehensive
HG/T 21574-94 Equipment lifting lugs http://bbs.hcbbs.com/viewthread.php?tid=11421&highlight=%C9%E8%B1%B8%B5%F5%B6%FA Equipment lifting lugs http://bbs.hcbbs.com/viewthread.php?tid=26729&highlight=%C9%E8%B1%B8%B5%F5%B6%FA
Note, what’s being executed now is 2008, not 94~~~~
HG/T 21574-2008 – this latest standard is quite comprehensive; it came into effect in October 2008. It covers not only the lifting lugs of towers but also their towing lugs, and it specifies detailed requirements regarding the minimum wall thickness of the equipment, making it easier to make choices
Lugs are generally made of Q235-A material. The gusset plate connecting to the tower body in the lifting lugs must be of the same material as the tower body. Also, if equipment is installed in low-temperature areas, appropriate consideration should be given to replacing the materials with ones such as 16Mn, which have better mechanical properties in such low-temperature environments. Because the cost of the lifting lugs accounts for only a small portion of the total equipment cost. :)
