Hardness test requirement
Hardness test requirement
(OP)
Hello everyone
I would like to have your help about this technical query
In our project specification, we said the following:
when required, hardness test shall be performed on.... "see page 3 of 3 in the attached file"
The contractor is proposing the following:
For P1 material weld and HAZ with PWHT hardness values shall be 200 BHN max.
For P1 material weld and HAZ without PWHT hardness values shall be 237 BHN max.
and the justification is given in page 1&2 of the attached file
Now what I want to understand: what does it mean "when required" in the spec and is there any deviations from what the contractor is proposing.
Thx in advance

RE: Hardness test requirement
You as the client have a project spec.
The contractor wants to do something differently.
You want us to tell you what to do with the contractors proposal ?
Don't hold your breath !

Whoever wrote the spec is irrelevant.
You, as the client own that spec as you, the client accepted that spec.
If you are not knowledgeable / experienced enough to be able to resolve this then give it to someone in your organisation who is.
RE: Hardness test requirement
Paragraph 5 of the contractor's justification is technically incorrect with respect to a threshold H2S partial pressure.

From what I understood, there is a deviation made by the contractor regarding the spec clause.
