RE: Corrosion Allowance in High Pressure Steam Pipeline
Is this a B31.1 or B31.3 line? What code are you building the line to?

Is it corrosion or erosion allowance???

Usually corrosion allowance is established by the end user. ASME codes do not report any corrosion allowance formula.
You have to establish a design life (DL) and a corrosion rate (CR). Your corrosion allowance is:
CA = DL(year) x CR (inch/year)
NACE (National Association of Corrosion Engineers) has a wealth of useful data.

You state:
"Vendor has said in his proposal, don't consider any corrosion allowance for these pipes(High Pressure Steam Pipes) as per ASME but has not defined, which part of ASME"
ASME piping and pressure vessel codes define a "corrosion allowance" to enable the designer to consider the effects of future wastage.....either corrosion or erosion or whatever.
The specific allowance for "corrosion" always comes form the piping or vessel purchaser.....it is not stated within any ASME code or standard.
This is because only the purchaser knows his particular process conditions.
My opinion only
