用于石油储存的焊接储罐

[中文适用范围]： 本附录规定了容量相对较小的现场安装储罐的要求，其承压部件的标称厚度不超过13毫米（1/2英寸）。承压部件包括壳体、加强板、平齐型清洁配件和平齐型壳体连接的壳体加强板，以及与壳体焊接的底板。13毫米（1/2英寸）的标称厚度限制不适用于：1）未与壳体焊接的底板；2）平齐型清洁口和平齐型壳体连接的底部加强板；3）平齐型清洁口的法兰和盖板；4）连接到壳体的平齐型壳体连接颈和平齐型壳体连接的法兰和盖板；5）喷嘴和人孔颈、其法兰和盖板；6）锚栓座组件和壳体压缩环。本附录仅当买方指定时适用，并限于设计金属温度-30°C（-20°F）或更高[当使用镇静细晶材料时为-40°C（-40°F）或更高]。本附录适用于第4节的任何材料，尽管单一允许应力未对高强度钢提供任何优势。本附录仅说明与本标准基本规则不同的要求。当未说明不同要求时，必须遵循基本规则；但应考虑风荷载的倾覆效应。典型尺寸和容量列于表A.1a至A.2b。 [外文原描述]： This standard establishes minimum requirements for material, design, fabrication, erection, and inspection for vertical, cylindrical, aboveground, closed- and open-top, welded storage tanks in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure is permitted when additional requirements are met. This standard applies only to tanks whose entire bottom is uniformly supported and to tanks in non-refrigerated service that have a maximum design temperature of 93 °C (200 °F) or less. This standard provides industry with tanks of adequate safety and reasonable economy for use in the storage of petroleum, petroleum products, and other liquid products. This standard does not present or establish a fixed series of allowable tank sizes; instead, it is intended to permit the purchaser to select whatever size tank may best meet his or her needs.
