	I have done many heat ex-changer designs where there is no corrosion allowance specified by client even if the material is CS . This is also supported by API 660. I would like to why there is no corrosion allowance required for tubes. __________________ RK

	Both? If so, I don't think any corrosion allowance is needed. __________________ In vino veritas; in cervisia carmen; in aqua E. coli.
