Weld Overlay or Cladding for small nozzle
Weld Overlay or Cladding for small nozzle
(OP)
Do you know if is possible to esecute cladding or weld overlay inside a LWN 2" nozzle? probably it's hard to do, the lenght of the nozzle is 300 mm c.ca.
Can you give me some referrement of similar cases? thank you very much at all.

I've never heard of cladding in a 2" long weld neck, but have often seen weld overlayed. It can be done - check with some fabricators / suppliers. One option is to use solid stainless/alloy nozzles, but if cracking is a concern then carbon with overlay will be preferred.

also PMI to verify alloy
are you in US OR CANADA?

this pipe is used for co2 gas, for the lower cost we select cs instead of the SS
and this pipe is 2m long.
we galvanize it after NDE.
the galvanization is bad for the screw.so if it has some screw you shouldn't galvanize it.

As you are talking a relatively short bore we have rolled in a liner, with and without grooves. This was mainly where we were getting erosion.
Off the box.
Another possibility.
