简介：
This STANDARD covers material, design, fabrication,
erection, and testing requirements for vertical, cylindrical,
aboveground, closed- and open-top, welded steel 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
(see 1.1.10). This STANDARD applies only to tanks whose entire
bottom is uniformly supported and to tanks in nonrefrigerated
service that have a maximum operating temperature of 90°C
(200°F) |
