一、总则 1.范围本文适用于炼油厂、石油化工厂在氢介质与含氢介质的加工生产、贮存的承压和非承压或其它设备。许多工艺设施,包括有内装液体或气体,在高温、高压下与氢气接触并连续操作的专用工艺设备。有时,设备所处的操作条件使碳钢同时发生物理化学变化,使得它不能适应安全操作,这时可以选用合金钢,但由于经济原因,应使用最低含量的合金钢去满足
I. General 1. Scope This article applies to refineries, petrochemical plants in the hydrogen medium and hydrogen medium processing production, storage of pressure and non-pressure or other equipment. Many process facilities include dedicated process equipment that contains liquid or gas in-line and is in continuous contact with hydrogen at elevated temperatures and pressures. Occasionally, the operating conditions in which the equipment is subjected make physicochemical changes to the carbon steel at the same time, rendering it inadaptable for safe operation, in which case it is possible to choose alloy steel, but for economical reasons, the lowest content of alloy steel should be used to satisfy
