Description

Full Description

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.
