This article is compared GB150 ＆ Chinese relative standard with ASME code about the clearance or overlap between two adjacent welds, upper and lower limit value of weld reinforcement, the calculation and opportunity for partial radial testing rate etc, and find about the difference. Also this article will point out the maneuverability during product fabrication, inspection or supervision for both standard and code, ASME relative clauses rationality and worthy reference for our pressure vessel standard
