The filler tower body is made of PP material; what are the mechanical property parameters of PP material?
Thread Content
I would like to ask fellow sailors: for a packing tower whose body is made of PP material, how should the thickness be determined? Could you provide the mechanical property parameters used for strength verification of PP material?
Basically, the towers that exist are made of metal materials, or they have a metal core with a non-metallic outer layer. I’ve never seen a tower whose main structure is made of PP plastic, which is a non-metallic material.
You can directly consult the manufacturer of the filler for this.
Using pure PP to construct tower bodies is very difficult, as its strength, pressure resistance, and temperature tolerance are insufficient
Towers with a metal lining over a non-metallic layer are generally used; the following standards can be referred to. On forums, HG T 4277-2011 – Technical specifications for steel towers with plastic linings, HG T 4173-2011 – PFA-lined packed towers, HG T 4371-2012 – PVC-composite lined towers for chemical applications, HG T 20678-2000 – Technical regulations for the design of lined steel tanks, and GB T 26501-2011 – General technical requirements for pressure vessels with fluoroplastic linings are commonly available
If the tower isn’t very tall, there are many cases where PP or PVC is used for its construction; for example, in exhaust gas absorption towers, those over 10 meters high aren’t particularly thick either – the main reason is cost-effectiveness.
