Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following technical solutions in the present invention are clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] The online monitoring platform for the safety margin and remaining life of the oil and gas transmission pipeline provided by the present invention is composed of a three-layer structure, namely a system layer, a function layer and an interface layer.

[0034] Among them, the system layer is mainly responsible for the expansion, maintenance and modularization of the system, the function layer is mainly the programming implementation of system pitting safety ...

Abstract

The invention provides an oil and gas transport pipeline safety margin and residual life online monitoring platform featured by comprising the following parts: a data acquisition module used for acquiring oil and gas transport pipeline related data information for assisting a decision module to make decisions; the decision module used for determining evaluation rules according to the data providedby the data acquisition module, wherein the evaluation rules comprise ASME B31G evaluation rules, DNV_RP-F101 evaluation rules, and API-579 evaluation rules; an evaluation module used for estimatingthe oil and gas transport pipeline residual strength and life according to the evaluation rules determined by the decision module. The online monitoring platform can realize synergy evaluation of various evaluation rules, can provide reliable data support for safety evaluation personnel to make correct evaluations, and comprises database technology, safety evaluation technology and assistance decision technology; the platform is stable, safe, practical, and expandable.

Description

technical field [0001] The invention relates to the fields of safety assessment and life prediction of corroded pipelines, in particular to an online monitoring platform for safety margin and remaining life of oil and gas transmission pipelines. Background technique [0002] In the research, it is found that in the safety assessment of metal oil and gas pipelines with pitting defects, the most practical and practical method is based on the relevant criteria of "residual strength evaluation", of which the most reference is The API-579 evaluation criteria and ASME B31G evaluation criteria promulgated by the United States, followed by the DNV-RP-F101 standard jointly issued by British Gas Company and Det Norske Veritas in 1999. The evaluation rules commonly used at home and abroad have considerable overlap in the application objects (evaluation objects), that is, due to the indiscriminate applicability of the rules, different evaluation rules are allowed for the same pitting de...
