Scope

This proposed new standard describes the acoustic emission (AE) testing method for atmospheric pressure metallic storage tank floor and the classification and evaluation of the results. It applies to the AE detection and monitoring of corrosion severity of atmospheric pressure metallic storage tank floor. It also aims to assist the inspectors assess the safety of metallic storage tank.

Purpose

Atmospheric pressure metallic storage tanks are widely used as storage equipment in petrochemical, aviation, port and other industries. They are used to store various raw oils, semi-finished oils, refined oils, aromatic products, liquefied gases, etc. The tank floor plays the role of transferring oil and supporting the weight of the tank. The outer surface is easily wetted by the contact with the foundation, and the inner surface is often exposed to the deposited moisture and impurities in the oil, so the tank floor is easily corroded. It is difficult to directly check the corrosion condition of the tank floor. The purpose of this document is to provide test method for the corrosion severity of atmospheric pressure metallic storage tank floor. It also provides the evaluation criteria of testing results, and realizes the non-opening inspection of the corrosion of the tank floor. The establishment of this document can solve the problem that there is no ISO standard for AE testing method of atmospheric pressure metallic tank floor. The main interested parties who will benefit from this document are users and testing institutes of atmospheric pressure metallic tank.
