Fabrication Considerations for Vanadium-Modified Cr-Mo Steel Heavy Wall Pressure Vessels, First Edition
standard by American Petroleum Institute, 04/01/2011
Description
This best practice report complements API 934-A and specifies additional fabrication considerations that should be observed when constructing a new heavy wall pressure vessel using vanadium-modified Cr-Mo materials intended for hydrogen service at elevated temperature and pressure. It applies to vessels that are designed, fabricated, certified and documented in accordance with ASME Code Section VIII, Division 2, including Paragraph 3.4 of the ASME Code, Supplemental Requirements for Cr-Mo Steels and ASME Code Case 2151, as applicable (or equivalent international codes).
Nominal material chemistries covered by this report are the vanadium-modified steels including 21/4Cr-1Mo-1/4V, 3Cr-1Mo-1/4V-Ti-B, and 3Cr-1Mo-1/4V-Cb-Ca steels. The interior surfaces of these vessels may have an austenitic stainless steel cladding or weld overlay to provide additional corrosion resistance.

Description
API TR 934-B – Fabrication Considerations for Vanadium-Modified Cr-Mo Steel Heavy Wall Pressure Vessels, Second Edition
This document is a best practice guideline to be used by fabricators, in conjunction with API RP 934-A, when constructing new heavy wall pressure vessels with vanadium-modified Cr-Mo steels intended for service in petroleum refining, petrochemical or chemical facilities.
These materials are primarily used in high-temperature, high-pressure services which contain hydrogen. The document provides typical practices to be followed during fabrication, based upon experience and the knowledge gained from actual problems that have occurred during the fabrication of vanadium-modified Cr-Mo steels.
