(a) Vessels or portions of vessels subject to corrosion shall be as required by UG-25 of section VIII of the ASME Boiler and Pressure Vessel Code (incorporated by reference; see 46 CFR 54.01-1) except as noted otherwise in this section. (b) The pressure portions of pressure vessels shall: (1) Normally have a corrosion allowance of one-sixth of the calculated thickness, or one-sixteenth.
ASME section viii, Div 1, Part UG [PDF Document]
ASME SECTION VIII - Thin Cylindrical Shells: Equations and Calculator: The formulae in ASME Section VIII, Division 1, paragraph UG-27, used for calculating the wall thickness and design pressure of thin wall pressure vessels, are:. C = Corrosion Allowance (0 for no corrosion; 0.0625 in. commonly used; 0.125 in. maximum); S = Maximum.
Requirement and Calculation of Corrosion Allowance for Piping and Valves in the Oil and Gas
Limiting the minimum corroded wall thickness to that recommended in BS 5500 or ASME VIII, but making an additional allowance for mill tolerance. Limiting the minimum wall thickness to 0.5 of the minimum design wall thickness or 3.2mm (as suggested in API RP 579 Level 1 rules for general metal loss).
What is "corrosion allowance" and why should I care about it? SAFTENG
These had to have a corrosion allowance of 1/16". This 1/16" would be added to the base metal and the total base metal could still be less then 1/4". As far as I know, this is the only reference to a required corrosion allowance in ASME Section VIII, Div. 1 and this paragraph has even been removed from the later editions of the Code.
ASME Section VIII, Division 2 Fatigue Analysis of Pressure Vessels and Heat Exchangers
• The need for corrosion allowance becomes sub-clause (-b) • A new sub-clause (-c) is added to relocate the deleted text from U-1(a)(3) by referencing damage mechanisms and service restrictions. Reference is made to ASME Section II, Part D, Appendix A, API RP 571 and WRC Bulletins 488, 489 and 490.

Corrosion Allowance. Corrosion allowance is defined as an extra thickness (e.g., 3mm) normally added to carbon and low alloy steel to mitigate the CO2 corrosion rate.. A summary of the requirements of the three Divisions of the ASME Section VIII is as follows; 1.0. ASME VIII-1Assuming E (Joint efficiency) is one, a thick walled cylinder is.

ASME BPV Code Section VIII D.1 states that wall thickness should always be at least 1/16 in, not considering corrosion allowance, material, or dimensions.. Corrosion allowance is constructing the vessels with thicker walls to allow for the thinning. the Peters, Timmerhaus, and West suggest 0.25 to 0.38mm annually or 3mm for 10 years.
