Dear Jorge MB,

The software our company used now is not a commercial sofeware, it is
an in house sofeware used in some design companys in china. programmed according to chinese insulation design Code. In the past,we didn't use CII,
and use another programme to analysis piping stress.That programme accept insualtion weight(including the weight of insulation and protective metal wall) per meter long.


Dear RICHARD AY,

Thank you for your reply. Why i ask this question is that,if you want to include the weight of protective metal wall(plate), you have to calculate the average density of insulation material and the metal plate.


Best Regards,
