[MW:14364] RE: 14360] Hastalloy C pump casing repair


Hi,

The pin hole leak could be  due to many factors.Since the product is a casting there could be other interlinked porosities. You may please take radiographs in the surrounding area to ensure that no other defects being present before proceeding further.

 Please see the link h2095 on repair recommendations of cast hastelloy.

What's the ASTM or hastelloy -C grade, C-4, C22, C276??

Appreciate your response.
