Problems solved by technology

At present, the existing damage pattern recognition has not yet introduced the intelligent recognition function, and most of the damage recognition in the risk assessment also needs to be entered based on the early identification of engineers. The combination of information systems, resulting in non-uniform criteria and inefficiency

[0084] 1. Judgment of high temperature H2S-H2 corrosion sensitivity (belonging to corrosion thinning)

[0085] Material: carbon steel, low alloy steel, 304 / 304L / 304H / 316 / 316L / 321 / 347 / 347H ("material" means the material of the affected pressure equipment, used for identification, other materials are not affected) .

[0086] Medium: H 2 S and H 2

[0087] Damage site: containing high temperature H 2 S and H 2 Media equipment and pipelines.

[0088] Damage form: a) Uniform corrosion, with ferrous sulfide scale formed at the same time, and may form a multi-layer scale structure; b) The scale on the metal surface is firmly bonded and has a gray luster, which is easy to be considered as a metal collective without corrosion .

Abstract

The invention discloses a method and system for intelligent identification of damage patterns of portable pressure-bearing equipment. Condition parameters are screened according to the damage catalog to obtain a combination of conditions; damage to pressure-bearing equipment is identified according to the damage identification rules and the combination of conditions. model. The invention can intelligently identify the material damage mode and its damage occurrence sensitivity under the current conditions under the premise of determining the screening conditions (such as material, temperature, medium and process) and according to the damage sensitivity discrimination rules.

Description

technical field [0001] The invention relates to the field of equipment damage identification, in particular to a method and system for intelligent identification of damage patterns of portable pressure equipment. Background technique [0002] For petrochemical, energy and power companies, the long-term safe and stable operation of the device can ensure that the company can reduce maintenance costs and increase economic benefits on the one hand, and can also reduce equipment accident rates on the other hand, ensuring production safety and social public safety. Since the 1960s and 1970s, industries such as petrochemicals and electric power have entered the stage of large-scale production. With the continuous improvement of service parameters (temperature, pressure, etc.) of devices and equipment, the complexity of logistics media and the diversification of structural forms , equipment and components began to show more and more damage modes, and gradually formed major types of ...
