It can be used as bar or pipe materials under SA-479 and SA-312, even though it is not listed under these specifications. The material if not heat treated as per specification shall be heat treated either before or during fabrication. (Refer: Mandatory Appendix 12 (Page 435) of ASME BPVC Section VIII Div 1, 2017 Edition.) The material must meet the chemical and physical requirements of SA 240 and the product and quality requirements of the applicable product specification). 24. Step 1- Surface Preparation: Surface irregularities must be removed so that they can not mask or confuse the image as defect. This figure shows the acceptance criteria for porosity (rounded indication) dispersion level. The minimum thickness used shall not be less than that calculated by the formulas given in UG-27 or 1-1 and no case less than 0.5 mm. Division 3 is supposed for designing pressure vessels that need internal or external operating at a pressure above 10,000 PSI.

It contains mandatory and nonmandatory appendices detailing supplementary design criteria, nondestructive examination and inspection acceptance standards. The ASME Code Section 8 is the construction code for pressure vessel and covers design, manufacturing and pressure vessel inspection and testing in the manufacturing shop. UG-23, UCS-11 & UNF-13, Subsection-C to be followed for acceptance respectively, For a wrought (Forged, Rolled, Extruded, etc.) product when there is no particular specification listed in subsection C, but there is an approved specification listed in subsection C of some other wrought product of that grade the product for which there is no specification can be provided. Search this Site! First off let us address some key differences in the characterization of an indication and what ultimately decides Acceptance or Rejection of said indication. For ASME pressure vessel manufacture certification, as well as Authorized Inspection Agency certification, Review the Pressure Vessel Certification article.

For seamless heads, E=1, If a) head to shell weld is fully radiographed (if Cat. ASME Code Section 8 edition is issued once every 3 years and addenda, once a year both on July 1st. For vertical vessels, hydrostatic pressure caused due to liquid with specific gravity = 1, 1ft of height = 0.43 psig. 14. These included the RT 'marking' categories of UW-11 (RT1, RT2, etc.) The ASME Section IX for welding and Section V for Non Destructive Testing are in this Group. 11.2 Film Evaluation ---- The acceptance or rejection of the material is by comparing the radiographic image to the agreed upon acceptance criteria. Based on the requirements of QW-191.1.2.2 in ASME Section IX any crack and incomplete fusion is unacceptable. Just wish some of these were not so expensive. Table 1A, 1B, and 3 including all the applicable notes. (b) A rounded indication is one of circular or elliptical shape with a length equal to or less than . (a) Rounded Indications. This will further assist you with acceptance criteria. The ASME Section VI for the heating boiler and Section VII are from this group.
