hai guys...

the question is
1) For low temperatures different types of steels is used explain any 5 types

i will give one example to all

Ex: 9%Cr steel is used for -167 degree centigrade to -170 degree centigrade.

2) Explain about how the corrosion formed in between the insulation
and pipe and how can we prevent and how can we find through NDE.
