T/HZBX 081-2023 Opening inspection specification for vertical steel welded drum type storage tank
Basic Information
Scope
This document specifies the basic requirements for the opening inspection and evaluation of the results of vertical cylindrical steel welded storage tanks. This document applies to the opening inspection of vertical cylindrical steel welded storage tanks (hereinafter referred to as storage tanks) designed for a design pressure of less than 0.1 MPa(G) and a nominal volume of not less than 1000 m3, built on the ground, and used to store petroleum, petroleum products, or chemical liquid media with a toxicity level of non-extreme or non-high hazard. The opening inspection of other storage tanks under normal or low pressure (with a working pressure of less than 0.1 MPa) and a nominal volume of less than 1000 m3 used to store other similar liquid media may refer to this document for implementation. This document does not apply to low-temperature storage tanks or mobile storage tanks.
