LINING, CLADING, WELD OVERLAYS. 1

[HOYA]

I.m a beginner in this field.

I'd like to know the difference among LINING, CLADING and WELD OVERLAY.

Thanks.

Refer to Section 21.6.5 of Companion guide to the ASME boiler & pressure vessel code Volume 2 By K. R. Rao

This can be viewed here:

I am soory, but I don't have Companion guide to the ASME boiler & pressure vessel code Volume 2. If you don't mind, please extract it and attache herein.

Hoya;
You can perform a search using Google for the above (lining, cladding and weld overlay). Regarding Volume 2 by Kao, the above we site is a preview of the book. Use the preview feature above and see if this book is what you need. If it is purchase it, we don’t violate copyright rules on this forum.

Hoya,
Lining, Cladding and Weld Overlay are methods of putting a corrosion resistant material between your process fluid and the less resistant base material of your pressure containment. Instead of a stainless steel pipe capable of containing the design pressure and have a proper corrosion resistance for the process fluid, you can use a similarly strong carbon steel pipie and use a stainless steel insert for corrosion protection of the carbon steel pipe. That lining the carbon steel pipe with corrosion resistent lining material.
For larger pipe or equipment, you can buy the carbon steel plate already having one side bonded to a thin layer of corrosion resistant material. The process of bonding corrosion resistant material to the carbon steel plate is called cladding. Read on the internet the various type of cladding (explosive bonding, friction bonding, you may even nuke it...)
However, the corrosion resistent material can be deposited on the less corrosion resistant material via welding process, in that case the process is called weld overlay.
Read again on the internet how to make the lining, cladding and weld overlay, when is applicable each process, then come back with questions.
Cheers,

gr2vessels,

Your reply is very helpful for me. I will tray again to find how to make the lining, cladding and weld overlay on the internet.

Thank you very much.
