Problems solved by technology

[0003] At present, domestic refining and chemical enterprises screen the pipelines that need thermal insulation modification by relying on experience or measuring the surface temperature of the pipeline to judge whether it needs to be modified. It is inaccurate and incomplete to judge only by the single index of pipeline surface temperature. Pipelines that are in urgent need of renovation are often put on hold, and pipelines that do not need renovation are included in the renovation list, resulting in the inability to efficiently use limited renovation funds

Embodiment 1

[0070] Select 10 thermal insulation pipelines of a petrochemical company as the evaluation object, sort the quality of the thermal insulation pipelines, and screen out the pipelines that need to be transformed.

[0071] Collect relevant data according to the 10 evaluation indicators that have been determined. On-site test and statistical data include: average heat dissipation loss, number of damaged points, and number of special-shaped parts. The rest of the data is provided by the petrochemical company's pipeline basic information ledger. The above information is compiled to compile a basic data table for pipeline insulation, as shown in Table 3. Show.

[0072] Table 3 Pipeline Insulation Basic Data Sheet

[0073]

[0074] Step 1: In this example, 3 experts with professional knowledge and experience in the field of pipeline insulation construct a comparative judgment matrix for 10 evaluation indicators. The 10 indicators have different influences on pipeline insulation, ...

Abstract

The invention discloses a method for evaluating the heat preservation performance of a pipeline. According to the method, ten evaluation indexes are adopted, a subjective and objective comprehensive evaluation method combining an analytic hierarchy process and a grey correlation analysis method and a comprehensive multi-index evaluation method for evaluating the heat preservation performance of the pipeline are combined, the two subjective and objective evaluation methods are combined, and the method considers the importance degree of indexes, and is not divorced from objective data, and is anevaluation method combining qualitative analysis and quantitative analysis. According to the method, the pipelines urgently needing heat preservation transformation can be screened out more reasonably, an accurate basis is provided for heat preservation upgrading transformation of the pipelines, the transformation funds are efficiently utilized, and under-repair and over-repair are avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline insulation, in particular to an evaluation method for pipeline insulation performance. Background technique [0002] There are a large number of process pipelines and steam pipelines in refining and chemical enterprises. Due to the large number and variety of pipelines, the lack of system regulations, management methods or poor implementation, there are many problems in the management of pipeline insulation in refining and chemical enterprises, and the energy consumption is low. High, not only will cause huge heat loss, but also cannot meet the production process requirements, affecting the economic benefits of the enterprise. With the increasing awareness of energy saving and environmental protection, refining and chemical enterprises pay more and more attention to the energy saving and consumption reduction of pipelines, and put forward higher and more refined requirements for the management of...
