Description

Technical Field

[0001] This utility model relates to the field of pressurization technology for crude oil pipeline seals, and in particular to a pressurization device for testing crude oil pipeline seals. Background Technology

[0002] Crude oil pipelines refer to pipelines that transport crude oil over long distances. Crude oil is the liquid phase of petroleum, and its chemical composition is divided into three main categories: paraffinic, naphthenic, and intermediate. After removing associated natural gas and formation water, crude oil that meets product sales standards is called commercial crude oil. Commercial crude oil is classified into light crude oil, medium crude oil, heavy crude oil, and extra-thick crude oil according to its density, and can also be distinguished according to its sulfur content and wax content. When installing crude oil pipelines, sealing components are required to seal the pipeline connections. Pressure testing is required when processing the sealing components.

[0003] Existing pressurization devices are difficult to use to perform pressure tests on the inside and outside of the seals, resulting in inaccurate test results.

[0004] To address this, a pressurization device for testing crude oil pipeline seals is proposed. Utility Model Content
